The following embodiments relate to a method and apparatus for transforming a garment pattern.
A garment appears in three dimensions when worn on a person's body, but it is more in two dimensions because it is actually a combination of pieces of fabric cut according to a two-dimensional (2D) pattern. Because fabric, which is a material for a garment, is flexible, it may vary in shape according to a body shape or motion of a person who wears it.
For example, to transform a cut line and/or a sewing line having various shapes to apply a design element to a garment, transformation may need to be applied to not only a pattern including the cut line or the sewing line but also another pattern that is sewed or connected to the pattern.
According to an embodiment, by linking a link between two-dimensional (2D) garment patterns forming a 3D garment, an edit of a pattern may be applied to other patterns linked with the pattern.
According to an embodiment, an edit of an entirety of a linked pattern may be applied to a partial pattern or an edit of a linked partial pattern may be applied to the entire pattern.
According to an embodiment, a batch edit may be performed on an original pattern and a pattern that is copied from or traces the original pattern.
However, the technical aspects are not limited to the aforementioned aspects, and other technical aspects may be present.
A method of transforming a garment pattern, the method includes receiving a selection input of a user with respect to a first pattern of 2D garment patterns, determining a second pattern linked with the first pattern, generating a link between the first pattern and the second pattern, receiving a pattern transformation input of the user with respect to one of the first pattern and the second pattern, and displaying a transformation result of the first pattern and the second pattern on both the first pattern and the second pattern based on the pattern transformation input of the user.

The displaying of the transformation result by applying the transformation result to both the first pattern and the second pattern includes setting a priority corresponding to the link according to whether the link is repeated or whether the link is flipped off, and applying the transformation result to the one pattern and the other pattern according to the priority.
The displaying of the transformation result by applying the transformation result to both the first pattern and the second pattern includes according to direction setting of the link, applying and displaying the transformation result, in which interlinked points are moved in a same or opposite direction in the first pattern and the second pattern, to both the first pattern and the second pattern.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. When describing the embodiments with reference to the accompanying drawings, like reference numerals refer to like elements and a repeated description related thereto will be omitted.
Operations to be described hereinafter may be sequentially performed but not necessarily. For example, the order of the operations may change, and at least two of the operations may be performed in parallel.
In operation 110, the electronic device may receive a selection input of a user for a first pattern of 2D garment patterns. In this case, the “first pattern” may be referred to as an “original pattern” or a “target pattern”. The first pattern may be, for example, an entire pattern corresponding to a complete single garment, such as a shirt, trousers, or a dress, or may be a partial pattern that forms one garment, such as an upper garment right side front pattern, a lower garment back pattern. In this case, the “selection input of the user for the first pattern” may be selecting the entire first pattern or a partial area of the first pattern.
In operation 120, the electronic device may determine a second pattern linked with the first pattern, based on the selection input of the user for the first pattern received in operation 110. The “second pattern” may be a pattern linked with at least a portion of the first pattern. Specifically, a pattern linked with at least a portion of the first pattern may be a pattern that is linked with the entire first pattern or a partial area of the first pattern. More specifically, linking with at least a portion of the first pattern may include linking by forming a sewing relationship with at least a portion of the first pattern, linking by forming a relationship in which editing is simultaneously performed on at least a portion of the first pattern asymmetrically, and linking by forming a relationship in which editing is simultaneously performed on at least a portion of the first pattern symmetrically.
For example, when the first pattern is an upper garment's right side pattern, the electronic device may determine a partial pattern corresponding to a partial area in which a pocket is positioned in the upper garment's right side pattern. Alternatively, when the first pattern is a lower garment back pattern, the electronic device may determine the second pattern to be a partial pattern corresponding to a partial area in which a back pocket is positioned in the lower garment back pattern. Alternatively, when the first pattern is an upper garment's right side pattern, the electronic device may determine the second pattern to be a sleeve's right side pattern that is linked with and is in a sewing relationship with an armhole part of the upper garment's right side pattern. The size of the second pattern may be the same as the size of the first pattern or may be smaller. There may be one or more first patterns and/or second patterns.
In an embodiment, a 3D garment and 2D garment patterns may be formed by a mesh including a plurality of polygons. According to embodiments, the mesh may be modeled in various manners. For example, the vertices of a polygon included in the mesh may be point masses, and the sides of the polygon may be represented as elastic springs that connect the point masses. Thus, the 3D garment may be modeled by a mass-spring model, for example. The springs may have respective resistance values against, for example, stretch, shear, and bending, depending on the material property of the fabric used. Alternatively, the mesh may be modeled by a strain model. A polygon included in the mesh may be modeled, for example, as a triangle or as a polygon having four or more sides. In some examples, in case of needing to model a 3D volume, the mesh may be modeled as a 3D polyhedron.
The vertices of the polygon(s) included in the mesh may be moved by an external force such as gravity and an internal force such as stretch, shear, and bending. If a force applied to each vertex is obtained by calculating the external force and the internal force, the speed of displacement and movement of each vertex may be obtained. Movements of the garment may be simulated through the movements of the vertices of the polygon(s) constituting the mesh in each time step. For example, when a garment configured as a polygonal mesh is draped over a 3D avatar, a natural 3D virtual garment based on the law of physics may be implemented. The vertices of the polygon(s) included in the mesh may move according to the action of an external force such as gravity and the action of an internal force such as stretch, shear, and bending. When a force being applied to each vertex is obtained by calculating the external force and the internal force, the speed of movement and displacement of each vertex may be obtained. Also, a movement of the virtual garment may be simulated through movements of the vertices of the polygons of the mesh in each time step. When a 2D pattern formed of a polygonal mesh is draped over a 3D avatar, a 3D virtual garment with a natural look based on the law of physics may be implemented.
The 3D garment according to an embodiment may include, for example, at least one of a virtual garment that fits a body size of a user, a virtual garment for a 3D virtual character, and a virtual garment for a 3D virtual avatar.
The 2D garment patterns may correspond to respective body parts forming a 3D garment. The 2D garment pattern may be a virtual 2D pattern that is modeled as a set of polygons for simulating the 3D garment. The 2D patterns may include pattern pieces, and each of the pattern pieces may be modeled, for example, as a polygonal mesh based on the body shape of the 3D avatar. In this case, the polygonal mesh may include a plurality of polygons (e.g., a triangle or a rectangle).
In operation 130, the electronic device may generate a link between the first pattern and the second pattern. The electronic device may determine whether preset points exist in the first pattern and the second pattern. The preset points may correspond to, for example, each edge point that may define the shape of each pattern or a sewing point, a straight line point, a curve point, a dart point, a seam line, or a center point on a line segment of a straight line (or a curve) of each pattern. However, the example is not limited thereto.
A link according to an embodiment may be a connection for easy pattern editing for some of linked patterns (e.g., the first pattern and the second pattern). For example, when transforming the first pattern to edit the first pattern, the electronic device may apply and display a result of the transformation of the second pattern linked with the first pattern. As described above, the link may be for applying a result of organically applying a result of pattern transformation to the linked patterns.
For example, when it is determined that preset points exist in the first pattern and the second pattern, the electronic device may generate a link by matching a first point preset to the first pattern with a second point preset to the second pattern. In this case, there may be one or more first points and second points. Alternatively, when it is determined that preset patterns do not exist in at least one of the first pattern and the second pattern, the electronic device may generate a link by matching a first point of the first pattern with a second point of the second pattern, wherein the first point and the second point are determined based on a length ratio between a first line of the first pattern and a second line of the second pattern. The electronic device may match the first point of the first pattern with the second point of the second pattern based on a simple length ratio. The electronic device may set a range from 0 to 1 to the first line set in the first pattern. The electronic device may generate a link also in a range from 0 to 1 for the second line to be linked in the second pattern. Alternatively, when a point exists in the first line, the electronic device may identify position coordinates (e.g., 0.4, 0.7) of a position where the point is positioned in the range from 0 to 1 and may match the first point with the second point by determining the position of the second point on the second line to generate the link based on a ratio of the point on the first line.
The method of generating the link based on the determination of the presence of preset points in the first pattern and the second pattern by the electronic device is further described with reference to
Alternatively, the electronic device may generate a link based on the determination of whether preset sewing lines exist between the first pattern and the second pattern. For example, when it is determined that preset sewing lines exist as a sewing pair between the first pattern and the second pattern, the electronic device may generate a link using the preset sewing lines. The electronic device may generate a link by connecting at least one link line between the preset sewing lines. The “link line” may be a line that connects patterns in which a link is generated therebetween, and for example, may be displayed as a dotted line including both arrows as link lines 270 of
The electronic device may generate a link by connecting the first point of the first pattern and the second point of the second pattern linked to the first pattern to each other by at least one link line. The electronic device may change at least one of the first point, the second point, and the at least one link line by editing by the user. The method of changing at least one of the first point, the second point, and the at least one link line by editing by the user by the electronic device is further described with reference to
In operation 140, the electronic device may receive a pattern transformation input of the user for one of the first pattern and the second pattern in which a link is generated (“linked”) in operation 130. The pattern transformation input of the user may include for example, at least one of an input to move a point positioned in the pattern in which the link is generated, an input to move a line segment positioned in the pattern in which the link is generated, and an input to transform a curvature corresponding to a curve of the pattern in which the link is generated. However, the example is not limited thereto.
In operation 150, the electronic device may apply and display transformation results of the first pattern and the second pattern to the first pattern and the second pattern based on the pattern transformation input of the user received in operation 140.
The electronic device may apply the pattern transformation input of the user with respect to one of the points positioned in one of the linked first pattern and the second pattern, line segments positioned in one of the patterns, and a curve of one of the patterns. For example, when the first pattern and the second pattern are patterns connected by sewing and the user transforms or modifies the first pattern by the link generated along the sewing line, the electronic device may identically apply the transformation or modification of the first pattern to the second pattern linked with the first pattern.
Based on the pattern transformation input with respect to a pattern, the electronic device may determine whether to apply link movement according to the pattern transformation input of the user to another pattern linked with the pattern. In accordance with the determination of whether to apply link movement, the electronic device may apply the pattern transformation input of the user to the pattern while applying link movement to the other pattern to perform simulation. The method of applying and displaying whether to change the link according to the pattern transformation input of the user to the first pattern and the second pattern by the electronic device is further described with reference to
The process of applying the pattern transformation input of the user to the first pattern and the second pattern by the electronic device is further described with reference to
In addition, the electronic device may allow the user to edit various properties corresponding to the link. The electronic device may apply the pattern transformation input of the user to the patterns according to an edited property (e.g., setting a link direction) differently. The electronic device may apply and display a transformation result, in which interlinked points in the first pattern and the second pattern are moved in the same or opposite direction, to the first pattern and the second pattern. The method of editing a property corresponding to a link by the electronic device is further described with reference to

The electronic device may generate a link between a pattern and another pattern or, as shown in

The electronic device may determine the presence of preset points in each of the patterns 210, 220, and 230. In this case, the presence of preset points may be included in information (e.g., metadata or pattern information) corresponding to each pattern.
When the preset points exist in each of the patterns 210, 220, and 230, the electronic device may generate a link by matching preset (or divided) points in each line of the patterns 210, 220, and 230.
As shown in the
For example, the electronic device may match pre-divided points in each line according to a distance ratio based on a point in which each pattern is sewed or may generate a link by matching points according to a predetermined matching rule for each point of each pattern.
Referring to
For example, among the patterns shown in the
When a preset point does not exist in a line of each pattern (e.g., the third pattern 230 and the fourth pattern 240), the electronic device may generate a link to fit a length ratio of points existing in interlinked patterns (e.g., the first pattern 210 and the second pattern 220).
The electronic device may set a line set between a point 211 and an intermediate point 213 of the first pattern 210 and a line set between a point 231 and a point 233 of the third pattern 230 to be the “first line” and may set a line set between a point 241 of the fourth pattern 240 and a point 243 to be the “second line”. In this case, a margin may be provided when setting the first line. The electronic device may set starting points of the first line in the first pattern 210, may set the intermediate point 213 in the first pattern 210, and then, may continue to set the first line from the intermediate point 213 by moving to the third pattern 230 while pressing a key, for example, ctrl. The electronic device may determine the first line by setting the points 231 and 233 of the third pattern 230. In other words, the electronic device may determine the first line by setting the point 211, which is an upper point of the first pattern 210, to be a starting point and setting the point 231, which is a lower point of the third pattern 230, to be an ending point. In addition, when setting the second line in the fourth pattern 240, the electronic device may allow the second line that starts from the point 211 and ends at the point 231 to correspond to the first line by changing the starting point and the ending point of the second line continued to the points 241 and 243 of the fourth pattern 240.
As described above, the electronic device may generate two link lines connecting the first pattern 210 to the linked third pattern 230 by forming virtual points having the same length ratio by applying the length ratio between two points set on the right line of the first pattern 210 to a line, which faces the first pattern 210, of the linked third pattern 230.
In addition, as shown in the
As described above, when preset points do not exist in one of the interlinked patterns, the electronic device may generate a link by matching the first points of the first pattern with the virtual points of the second pattern such that the length or length ratio of the first line formed by the preset points matches the length or length ratio of the second line formed by the virtual points of the second pattern.

As described further with reference to
When changing a link line, a pre-generated link line, a link line changed by the edit of the user, and sewing lines used as link lines may also be displayed on the screen.
In operation 410, the electronic device may determine whether to move a link based on a pattern transformation input of a user with respect to one pattern. The electronic device may determine whether to apply link movement according to the pattern transformation input of the user to another pattern linked to the pattern. The electronic device may, for example, determine whether to perform link movement on the other pattern according to the pattern transformation input of the user with respect to one of a point and a line on one of the linked first pattern and the second pattern. The “link movement” may correspond to the movement of a line or a link point in linked patterns. In other words, the “link movement” may refer to the movement of the second pattern linked with the first pattern according to an input with respect to a point or a line including the link in the first pattern. In other words, the “link movement” may refer to the moving interlinked patterns together by the link. As a result of the “link movement”, outer lines of the patterns related to the link point or the line may be transformed. Accordingly, the electronic device may display the transformation result of the pattern. According to an embodiment, as a link point moves by the “link movement”, the length of a line segment of which an end point is the link point may extend or may be reduced. According to another embodiment, an area of the pattern may increase or decrease according to the link movement with respect to line segments or a linked point of linked patterns. In this case, the “interlinked patterns” may be construed to include any other patterns connected to directly linked patterns by sewing in addition to directly linked patterns by the link line. An operating principle of the link movement is further described with reference to
Based on the type of a link, the electronic device may determine whether to move the link according to a type of a pattern transformation input of the user (e.g., an input to move a point positioned in a pattern in which the link is generated, an input to move a line segment positioned in the pattern in which the link is generated, or an input to transform a curvature corresponding to a curve of the pattern in which the link is generated). For each type of link, the electronic device may determine whether to apply link movement according to the pattern transformation input of the user to the other pattern. In this case, the type of the link may include, for example, a first type generated between preset points, a second type generated between a preset point and an arbitrary point on a curve, a third type generated between a preset point and an arbitrary point on a straight line, a fourth type generated between arbitrary points on a straight line, and a fifth type generated between arbitrary points on a curve, but the example is not limited thereto. The first type may correspond to a link generated between a first point of one pattern and a second point of the other pattern. The second type may correspond to a link generated between the first point and an arbitrary second point on a curve of the other pattern. The third type may correspond to a link generated between the first point and an arbitrary second point on a straight line of the other pattern. The fourth type may correspond to a link generated between an arbitrary first point on a straight line of the one pattern and an arbitrary second point on a straight line of the other pattern. The fifth type may correspond to a link generated between an arbitrary curve of one pattern and an arbitrary curve of the other pattern.
For example, when the pattern transformation input of the user corresponds (matches) one of the first type, the second type, and the fifth type, the electronic device may determine to perform link movement. Accordingly, the electronic device may apply, to the other pattern, the link movement according to the pattern transformation input of the user. In addition, when the pattern transformation input of the user corresponds (matches) to one of the third type or the fourth type, the electronic device may determine not to perform link movement. Accordingly, the electronic device may not apply, to the other pattern, the link movement according to the pattern transformation input of the user.
Depending on the embodiments, the electronic device may determine whether to apply, to the pattern or the other pattern, a curvature change according to the pattern transformation input of the user based on whether one of the first point of the pattern or the second point of the other pattern is a control point at which a curvature change is allowed. The electronic device may apply the curvature change to the other pattern based on the determination of whether to apply the curvature change. In this case, the control point at which the curvature change is allowed may correspond to, for example, a point including a Bezier handle shown in the first pattern in the first type of link of
Alternatively, unlike the above descriptions, the type of link may be, for example, one of a first type {circle around (1)} in which a first point of the first pattern is a curve point positioned on a Bezier curve including a Bezier handle and a second point is a predetermined straight line point positioned on a straight line segment of the second pattern, a second type {circle around (2)} in which a first point of the first pattern is a predetermined straight line point positioned on a straight line segment of the first pattern and a second point is an arbitrary point that is not designated as a point on a straight line segment of the second pattern, a third type {circle around (3)} in which a first point of the first pattern corresponds to an arbitrary point that is not designated as a point on a straight line segment of the first pattern and a second point is a predetermined point on a straight line segment of the second pattern, a fourth type {circle around (4)} in which a first point of the first pattern corresponds to an arbitrary point that is not designated as a point on a straight line segment of the first pattern and a second point is a predetermined point on a curved line segment of the second pattern, a fifth type {circle around (5)} in which a first point of the first pattern is a predetermined first curve point positioned on a curved line segment of the first pattern and a second point is an arbitrary point that is not predetermined on a curved line segment of the second pattern, a sixth type {circle around (6)} in which a first point of the first pattern corresponds to an arbitrary point that is not designated as a point on a curved line segment of the first pattern and a second point is a predetermined curve point on a curved line segment of the second pattern, and a seventh type {circle around (7)} in which a first point of the first pattern corresponds to a predetermined curve point on a curved line segment (Bezier curve) of the first pattern and a second point is a predetermined straight line point on a curved line segment of the second pattern without Bezier, but the example is not limited thereto. The method of determining whether to move a link based on the type f link is further described with reference to
In addition, the type of link may further include an indirect link in which an adjacent point or an adjacent line to a point on a linked line moves together by being affected by a link movement input.
In operation 420, the electronic device may apply and display a transformation result of the pattern and a transformation result of the other pattern linked with the pattern according to the determination in operation 410 with respect to whether to move a link.
The electronic device may set a priority corresponding to the link according to whether the link is repeated or flip off of the link. The electronic device may apply the link movement according to the set priority corresponding to the link. For example, the electronic device may set a priority corresponding to the link based on whether the link is a repeated link positioned between two links and whether the link is a flip off link of repeated links. The electronic device may set a high priority to the repeated link. In addition, the electronic device may set a high priority to the link that is set to flip off among the repeated links.
The electronic device may apply a transformation result to the pattern or the other pattern according to the priority. The electronic device may sequentially apply the link movement to the pattern or the other pattern according to the set priority. The method of applying the transformation result according to the set priority corresponding to the link is further described with reference to
For example, as shown in the
In addition, the electronic device may also perform link movement on points indirectly linked with the link points according to the movement of the link points. For example, when an indirect link in which a link is generated again is formed for a link-moved pattern, the electronic device may move a point and/or a line segment close to a point on the linked line segment by applying the influence of the link movement input. In this case, the “indirectly linked points” may be, when a link is set to a link-moved location, in other words, points moved by being affected by the link movement input among points (or line segments) near the point on the linked line (line segment).

The electronic device may perform simulation to symmetrically move interlinked points in the first pattern 610 and the second pattern 620 or move in the same direction according to the setting of a link direction in editing properties corresponding to the link. In this case, the setting of the link direction may be determined by setting a flip function.
When moving the first link point 611 of the interlinked link points 611 and 621 upwardly in the
For example, the user may set the link editing property to flip off through the UI as shown in the
When the link property is set to flip off, the electronic device may symmetrically move the interlinked points 615 and 625 in the first pattern 610, and the second pattern 620.
Alternatively, when the user presses a shortcut key (e.g., U) while moving the first link point 611 to the first link point 615 or sets a property setting in link edit to flip on, the electronic device may flip the link direction. In this case, when the user moves the first link point 615 to the inside of the first pattern 610 as shown in the
When the link property is set to flip on, the electronic device may move the interlinked link points 615 and 627 in the first pattern 610 and the second pattern 620 in the same direction.
Furthermore, the electronic device may identically apply transformation by an input of the user to a line that is in a symmetric relationship or instance relationship with a link line. In this case, the “instance relationship” with respect to a specific line or pattern may be a copied line or copied pattern from the corresponding line or pattern.

In addition, when moving the first point, if the second point is positioned on a line segment of the second pattern, the electronic device may curvature move the second point if the line segment of the second pattern is a curve and if the line segment of the second pattern is a straight line, the second point may not move and may remain in the original position.
The rule of performing the link movement is as follows.
When the first point of the first pattern is moved, the electronic device may perform link movement on the second point of the second pattern linked with the first point. However, if the first point is moved but a point linked with the first point is not a preset second point in the second pattern and is an arbitrary point that is not designated as a point on a line segment of the second pattern, the electronic device may perform link movement only when the line segment of the second pattern is a curve and when the linked point is a straight line, the electronic device may not perform link movement.
For example, the first type {circle around (1)} may correspond to a case in which the first point of the first pattern is a curve point positioned on a Bezier curve including a Bezier handle and the second point is a predetermined straight line point positioned on a straight line segment of the second pattern.
In the first type {circle around (1)}, when a curve point on a curve of the first pattern is moved, the electronic device may perform link movement on the straight line point of the second pattern linked with the curve point of the first pattern. In this case, the curve of the first pattern may be, for example, a Bezier curve or a spline curve, but the example is not limited thereto.
The first curve point of the first pattern may include a Bezier handle in an arrow shape for curvature change. in this case, the user may change the curvature of the curve of the first pattern using the Bezier handle included in the first curve point. When the curvature editing is performed on the first curve point of the first pattern, the electronic device may not perform link movement on the straight line point of the second pattern.
The second type {circle around (2)} may correspond to a case in which the first point of the first pattern is a predetermined straight line point positioned on a straight line segment of the first pattern and the second point is an arbitrary point that is not designated as a point on the straight line segment of the second pattern.
The third type {circle around (3)} may correspond to a case in which the first point of the first pattern is an arbitrary point that is not designated as a point on a straight line segment of the first pattern and the second point is a predetermined point on the straight line segment of the second pattern.
The fourth type {circle around (4)} may correspond to a case in which the first point of the first pattern is an arbitrary point that is not designated as a point on a straight line segment of the first pattern and the second point is a predetermined point on the curved line segment of the second pattern.
If the pattern transformation input of the user corresponds to one of the second type {circle around (2)}, the third type {circle around (3)}, and the fourth type {circle around (4)}, the electronic device may perform link movement when moving an entirety of a straight line segment by selecting the straight line segment (itself) in the first pattern for the link movement because a linked point exists in the opposite side. However, when moving an arbitrary point on the straight line segment of the first pattern (e.g., when selecting one of both end points of the straight line segment and moving the point) and the second point of the second pattern linked with the first pattern is an arbitrary point of the line segment of the straight line, link movement may not be performed.
The fifth type {circle around (5)} may correspond to a case in which the first point of the first pattern is a predetermined first curve point positioned on a curved line segment of the first pattern and the second point is an arbitrary point that is not designated as a point on the curved line segment of the second pattern. In this case, the curve point of the first pattern may include a Bezier handle in an arrow shape for curvature change.
The sixth type {circle around (6)} may correspond to a case in which the first point of the first pattern is an arbitrary point that is not designated as a point on a curved line segment of the first pattern and the second point is a predetermined curve point on the curved line segment of the second pattern.
When the pattern transformation input of the user corresponds to one of the fifth type {circle around (5)} and the sixth type {circle around (6)}, the electronic device may perform link movement with applied curvature to the second curve of the second pattern linked with the first point when moving the first point of the first pattern. When performing link movement with curvature, the electronic device may perform link movement on the second point of the second pattern.
The seventh type {circle around (7)} may correspond to a case in which the first point of the first pattern corresponds to a predetermined curve point in a curved line segment (a Bezier curve) of the first pattern and the second point is a predetermined straight line point in a curved line segment without Bezier of the second pattern. In this case, the curve point of the first pattern may include a Bezier handle in an arrow shape for curvature change.
When the link type is the seventh type {circle around (7)}, the electronic device may perform curvature movement on the line segment of the second pattern using the Bezier handle on the Bezier curve.
As described above, for each type of link, the electronic device may determine whether to change a link according to the pattern transformation input of the user to the other pattern. The electronic device may determine whether to apply, to the pattern or the other pattern, a curvature change according to the pattern transformation input of the user based on whether one of the first point of the pattern or the second point of the other pattern is a control point at which a curvature change is allowed (e.g., a link point including a Bezier handle).
When multiple link movements are repeated, the electronic device may assign a priority corresponding to a link movement by a predetermined rule. The method of applying link changes according to the priority is further described with reference to
The electronic device may perform a link change according to the following rule.
For example, when the user selects both the first point of the first pattern and the second point of the second pattern that are interlinked with each other as targets of link movement as shown in the
When the user sets a link between the first point of the first pattern and the second point of the second pattern but as shown in the
The electronic device may set a priority corresponding to the link based on whether the link is a repeated link positioned between two links and whether the link is a flip off link of repeated links. The electronic device may apply a transformation result by sequentially applying a link change to the pattern or the other pattern according to the priority.
For example, when a first link 940 and a second link 950 are set between the first pattern and the second pattern and repeatedly linked points 960 exist between the first link 940 and the second link 950, the electronic device may assign a high priority to a link that is line-moved with respect to the repeatedly linked points 960.
In addition, when the electronic device performs line movement with respect to repeatedly linked links, the electronic device may assign a higher priority to a flipped-off link. In other words, the electronic device may assign a higher priority to the second link 950 that is line-moved than the first link 940 that is point-moved.
In an embodiment, setting (or assigning) a priority to repeated links with multiple repeated links may prevent patterns from being individually moved by coordinate movement based on different references for moving directions of points.
The user may select a “Trace as a Pattern (with Link)” function to trace a portion of a first pattern (e.g., an upper garment pattern of a garment) as the
In this case, editing of the second pattern may be identically applied to the first pattern as the
For example, when a position of a dart line connected to an upper garment right sleeve in the 2D garment patterns 1110 is changed to 2D garment patterns 1130 shown in a
As described above, in an embodiment, the user may easily identify an edit result by identically applying an edit of the 2D garment pattern to the 3D garment by linking a pattern transformation input (e.g., an edit of the pattern (or a change in the setting of the pattern)) of the user for the 2D garment patterns with the 3D garment.
The UI 1210 may display 2D garment patterns (e.g., the first pattern and the second pattern) for a 3D garment and/or the 3D garment. The UI 1210 may receive a selection input of a user with respect to the first pattern of the 2D garment patterns. The UI 1210 may receive a pattern transformation input of the user with respect to one of the first pattern and the second pattern. The UI 1210 may receive an input of the second pattern selected by the user in association with the first pattern of the 2D garment patterns. For example, the UI 1210 may receive a user input with respect to the 2D garment patterns displayed in a 3D space through a stylus pen or a mouse click.
The processor 1230 may determine the first pattern and the second pattern based on a selection input of the user with respect to the first pattern or a random selection input of the user with respect to the first pattern and the second pattern. For example, when the user inputs a selection input with respect to the first pattern, the processor 1230 may automatically determine the second pattern linked with the first pattern. This may be a case in which the first pattern and the second pattern are linked in a sewing relationship. For example, when the user inputs a selection input that randomly selects from the first pattern and the second pattern, the processor 1230 may determine the first pattern and the second pattern by a link between the first pattern and the second pattern.
The processor 1230 may generate a link between 2D garment patterns (e.g., the first pattern and the second pattern) displayed through the UI 1210. The processor 1230 may apply and display, on the display 1250, a transformation result for the first pattern and the second pattern to the first pattern and the second pattern based on a pattern transformation input of the user with respect to one of the first pattern and the second pattern in which a link is generated (“linked”). A simulation may be performed.
The display 1250 may output at least one of the 2D garment patterns and/or the 3D garment to which the transformation result for the patterns is applied by the processor 1230. The display 1250 may display the 2D garment patterns and/or the 3D garment to which the pattern transformation input is applied by the processor 1230.
The memory 1270 may store information on the second pattern selected by the user, wherein the information is received through the UI 1210. The information on the second pattern may include, for example, position coordinates of the second pattern, the size of the second pattern, a distance, and a direction from the first pattern to the second pattern, but the example is not limited thereto.
The memory 1270 may store information on the first pattern and the second pattern in which a link is generated and/or information on the pattern transformation input of the user with respect to the first pattern and the second pattern. The memory 1270 may store a result (e.g., the 2D garment patterns and/or the 3D garment) of simulation that is performed by applying the pattern transformation input of the user to the first pattern and the second pattern.
Further, the memory 1270 may store a variety of information generated in the processing process of the processor 1230 described above. According to an embodiment, the memory 1270 may store a program implementing the garment pattern transformation method described with reference to
In addition, the processor 1230 may perform at least one of the methods described with reference to
The processor 1230 may execute a program and may control the electronic device 1200. Program code to be executed by the processor 1230 may be stored in the memory 1270.
The electronic device 1200 according to an embodiment may receive data from the user through an I/O device and may output generated data. For example, the electronic device 1200 may receive an input (e.g., selection of 2D garment patterns) of the user through the I/O device and may output a result of applying a pattern transformation input of the user to the 2D garment patterns by a link generated according to the user's input. The electronic device 1200 may be connected to the external device (e.g., a personal computer (PC) or a network) through the I/O device and may exchange data with the external device.
The electronic device 1200 according to an embodiment may further include other components not shown in the drawings. For example, the electronic device 1200 may further include a communication module that provides a function for the electronic device 1200 to communicate with other electronic devices or servers via a network. In addition, for example, the electronic device 1200 may further include other components such as a transceiver, various sensors, and a database.
