The present disclosure generally relates to computer graphics, and at least one particular implementation relates to the in-context adjustment of a paint stroke characteristic.
Painters refer to the mark caused by the movement of a physical paint brush over a medium, such as a canvas, as a paint stroke or brush stroke. Similarly, graphics designers can use computer applications can create virtual paint strokes, defined by the movement of a virtual paint brush (or brush icon) along a path on a display. Graphic designers prefer using these virtual paint strokes instead of using straight lines, curves or other templated shapes, due to the visually appealing non-uniformity of the region or regions that can be defined by a single paint stroke.
Due to this non-uniformity, however, alteration of a paint stroke rendered on a display is oftentimes difficult, onerous and counterintuitive, and is always performed using a process that is non-analogous to the alternation of a physical paint stroke. For example, in many typical computer graphics applications, characteristics of a rendered paint stroke must be adjusted by selecting options on various nested menus, which may be distally disposed across the virtual desktop from the paint stroke itself.
In accordance with one general implementation, a first user input selecting a path of a paint stroke rendered on a display is received, an anchor point on the path is defined based on the first user input, and a characteristic adjustment control is rendered adjacent to the anchor point. A second user input is received via the characteristic adjustment control, and a characteristic of the paint stroke is adjusted at the anchor point based on the second user input.
Implementations may include one or more of the following features. For example, the first user input may be a mouse down event on the path, and the second user input may be a mouse drag event. Alternatively, the first user input and/or the second user input may be keyboard keystrokes. The paint stroke characteristic may be a width characteristic of the paint stroke, a color characteristic of the paint stroke, a spacing characteristic of sub-elements of the paint stroke, a jitter characteristic of the sub-elements of the paint stroke, an opacity characteristic, an angle characteristic of the paint stroke, or a fall-off characteristic of the paint stroke. The characteristic adjustment control may include a first drag point handle aligned along an axis intersecting the anchor point and perpendicular to the path, and the second user input may further include a mouse drag event dragging the first drag point handle.
In additional examples, the characteristic adjustment control may include a second drag point handle aligned along the axis on an opposite side of the path than the first drag point handle, the first and second drag point handles being equidistant from the anchor point. A third user input selecting the anchor point may be received, and the anchor point may be deleted based on receiving the third user input. Rendering the characteristic adjustment control adjacent to the anchor point may further include rendering the characteristic adjustment control over the anchor point. The paint stroke may include a plurality of sub-elements. The paint stroke may be defined by a movement of a brush icon along the path.
In further examples, the paint stroke may be re-rendered based on the adjusted paint stroke characteristic, and the path may be rendered over the paint stroke. Adjusting the paint stroke characteristic at the anchor point may further include adjusting the paint stroke characteristic at the anchor point and an adjacent point adjacent to the anchor point, based on the second user input. Adjusting the paint stroke characteristic at the adjacent point is further based on a fall-off value. A third user input selecting the path may be received, a second anchor point may be defined based on the third user input, and a characteristic of the paint stroke may be adjusted at the second anchor point based on the second user input. Alternatively, a third user input may be received, and the anchor point may be translated along the path based on the third user input. The third user input may be a mouse drag event along the path or along an axis.
According to another general implementation, a computer program product is tangibly embodied in a machine-readable storage medium. The computer program product includes instructions that, when read by a machine, operate to cause a data processing apparatus to receive a first user input selecting a path of a paint stroke rendered on a display, define an anchor point on the path based on the first user input, and render a characteristic adjustment control adjacent to the anchor point. The computer program product also includes instructions that operate to cause a data processing apparatus to receive a second user input via the characteristic adjustment control, and adjust a characteristic of the paint stroke at the anchor point based on the second user input.
According to another general implementation, a device includes a display, an input device, and a processor. The display renders a paint stroke, and renders a characteristic adjustment control adjacent to an anchor point. The input device, which may be, for example, a mouse or a keyboard, receives a first user input selecting a path of the paint stroke, and receives a second user input via the characteristic adjustment control. The processor defines the anchor point on the path based on the first user input, and adjusts a characteristic of the paint stroke at the anchor point based on the second user input.
The details of one or more implementations are set forth in the accompanying drawings and the description, below. Other potential features and advantages of the disclosure will be apparent from the description and drawings, and from the claims.
Like reference numbers represent corresponding parts throughout.
Initially, the characteristic to be adjusted may be any characteristic that defines the overall look or effect of the paint stroke. Specific examples include, but are not limited to, a width characteristic of the paint stroke, a color characteristic of the paint stroke, a spacing characteristic of sub-elements of the paint stroke, a jitter (or spread) characteristic of the sub-elements of the paint stroke, an opacity characteristic, an angle characteristic of the paint stroke, a brush icon, or a fall-off characteristic.
In more detail, the process 100 begins (S101) with the rendering of a paint stroke on a display (S102).
Using a mouse, for example, a single paint stroke may be created when the user clicks and holds down a mouse button (a mouse down event) and moves the mouse with the mouse button held down (a mouse drag event), then releases the mouse button at the desired destination point (a mouse up event). Using a touch screen device, a single paint stroke is created when the user touches the touch screen device (a finger down event), moves the finger across the screen (a finger drag event), and removes the finger from the screen (a finger up event).
The movement of a finger across a touch screen device display maps the path displayed on the screen, in a 1:1 relationship in two dimensions, such that a movement with the finger of one distance unit in any direction causes the cursor to also move one distance unit, creating a path that is one distance unit long. Due to scaling, acceleration and other factors, the movement of cursor on a display, caused by a mouse, keyboard, or joystick input across a physical desktop may not have a 1:1 relationship in two dimensions.
Although the exemplary paint stroke 201 is sinusoid-shaped, it can also be any other shape, as long as the paint stroke is defined by a movement of the brush icon along a continuous path. Other example paint strokes may include only a single point, may be exactly straight or curved, may form shapes such as polygons, circles or spirals, or could intersect, overlap and double-back on the path. In an alternate implementation, rendering a paint stroke does not include user input, but instead includes, for example, receiving an input which causes a paint stroke to be automatically rendered, or accessing a stored path.
If the user were to release the mouse button and re-click on the mouse button during the movement, thereby generating a discontinuity in the path, two paint strokes would be created. Although the adjustment of a characteristic of a paint stroke is described herein as being applied to a point on a path, the characteristic may also be applied to affect multiple paths of multiple paint strokes.
Although the paint stroke 201 is illustrated as a single, continuous region, it need not be. For example, and as shown in
A jitter or spread characteristic is associated with the sub-elements to randomize or offset the position of sub-elements with respect to the path, where jitter represents an alternating offset or deviation of the sub-elements from the path. By way of example,
The path 206 of the paint stroke 201 may be rendered over the paint stroke 201 (S104), to make the path 206 visible (or more visible) to the user. Such rendering occurs, for example, by placing a visual layer depicting the path 206 nearer to the user than (or above) a visual layer depicting the paint stroke 201, by adjusting a transparency characteristic of the paint stroke 201 such that the path 206 becomes visible to the user, by highlighting the path 206, or by using other approaches. By rendering the path 206 over the paint stroke, it is easier for the user to locate and select a portion of the path 206 for adjustment of the paint stroke 201. In an alternate implementation, such as where the paint stroke 201 is narrow, or where the position of the path 206 may be easily implied, or where it is not intended that the user select the path 206, the path 206 is not rendered, or the path is rendered under the paint stroke 201.
A user input selecting the path 206 of a paint stroke 201 is received (S105). As illustrated in
The selection of the point 302 on the path 206 may also occur by selecting and holding down a mouse button (i.e. a mouse down event) alone, by touching the path 206 using a touch screen device, by selecting the path and scrolling to a position, by using a keyboard keystroke, by voice input, by accessing a stored position, or by utilizing any other input approach. The user input selecting the path 206 may also be a double-clicking event, or an option-clicking event on an area of interest on the paint stroke 201.
The selected point may be an anchor point, which is the location along the path where the user intends characteristic adjustments to the paint stroke 201 be focused. The user is also provided with the option of translating the anchor point from a previously-selected location on the, by way of a translation maneuver. A translation maneuver could be used, for example, when the desired anchor point is obscured by another graphical element, or where, upon selection of the anchor point, the user realizes that a different location was intended or desired.
As illustrated in
The anchor point 401 may be highlighted (S107) to increase the visibility of the anchor point 401, and to provide a visual reference of the anchor point 401 with respect to other graphical elements. Highlighting may refer to the changing the color of the anchor point 401 with respect to the path 206 or the paint stroke 201, by superimposing a symbol or marker 402 to make the anchor point 401 more easily identifiable, or by using other approaches. In
A characteristic adjustment control 501 is rendered adjacent to the anchor point 401 (S109). In
In other example implementations, different characteristic adjustment controls may be used. For example, the characteristic adjustment control 501 may have only one drag point handle, or may have four or more drag point handles or sub-handles. The drag point handles may be aligned on other axis as well, such as an axis parallel or tangential to the path, or offset by 45° instead of a 90°. Additionally, while the paint stroke characteristic adjustment control 501 is shown as being rendered over the anchor point 401, in other example implementations the characteristic adjustment control is rendered at a location near to, but not over the anchor point 401, or is dynamically adjusted to be rendered adjacent to the anchor point as the drag point handles are adjusted.
A user input is received via the characteristic adjustment control (S110). The user input may be, for example a mouse drag event, in which the user moves a mouse, a keystroke input, a touch screen device input, a joystick input, a verbal input, or another input. The user input may be indicative of a translation input, by which the user intends to translate the anchor point 401 to another point on the path 206, or the user input may be indicative of an adjustment input, by which the user intends to adjust a characteristic of the paint stroke via the characteristic adjustment control 501. For example, adjustment criteria may define that a mouse drag event input along axis 504 or a mouse down event on the first drag point handle 502 be interpreted as a characteristic adjustment control, translation criteria may define that a mouse drag input along the path or along an X-axis of a mouse, or a keyboard keystroke, be interpreted as a translation input.
In the case of a mouse or joystick input device, the reception of a user input via the characteristic adjustment control may refer the selection and adjustment of a portion of the characteristic adjustment control with a cursor. In the case of a keyboard input device, the reception of a user input via the characteristic adjustment control may refer to the selection of a portion of the characteristic adjustment control, such as by using a keyboard shortcut or the TAB key, the display and entry of a desired characteristic value, such as by numerical entry or arrow input, and updating of the position of the selected portion based on the entered value. In any case, the characteristic adjustment control refreshes to adjust the position of the selected portion based on the input, to provide the user with real-time or near real-time feedback of the magnitude of the adjustment.
If the user input (received at S110) is determined to be a translation input (S111), the anchor point is translated along path based on that user input (S112).
In various implementations, the translation input may include a movement of the cursor along the path, or along an axis (such as the X-axis) of a mouse. If the path is a spiral-shaped path, it may be onerous to expect the user to move the cursor 301 along that path, especially if inadvertent deviation from the path would reset the position of translation to the original anchor point. Thus, translation of the anchor point along a spiral-shaped path may be better realized by the movement of the input device along a predetermined axis, such as an X-axis.
Alternatively, however, such as where the path is generally oriented along the Y-axis, it is more intuitive for a user to move the cursor 301 along the path than along a predetermined axis that is not the Y-axis of the input device. Thus, translation of the anchor point may be better realized by a path-wise movement. Since both approaches work well for different shape types, the mapping of translation input from a user input movement may be automatically performed based on the size, shape or orientation of the path 206, to thereby make the entry of the translation input easier and more intuitive for the user.
If the user input is not determined to be a translation input (S111), it is determined whether the user input is an adjustment input (S113). If the user input is determined to not be a translation input (S111) or an adjustment input (S113), an error may have occurred and the user is again prompted to enter the input again (S110). If the user input is determined to be an adjustment input (S110), a characteristic of the paint stroke is adjusted at the anchor point based on the user input (S114), and the paint stroke is re-rendered based on the adjusted paint stroke characteristic (S115). After having drawn a paint stroke, the user can simply click the point along the stroke that they wish to alter, causing an on-screen control to appear. The on-screen control allows the user to modulate the intensity of the characteristic by pulling a control handle, which updates in real-time or near real-time, to display the result on the stroke as the control is adjusted.
The magnitude of the characteristic adjustment is determined by the change in position of the drag point handles. For instance, for a distance characteristic adjustment such as a jitter characteristic, a spacing characteristic, or a width characteristic, a movement of the drag point handles of one distance unit may map to an absolute or relative change of one distance unit in the distance characteristic, or a scaling factor may be applied to reduce or amplify the effect of the movement. In an example implementation in which the distance between the drag point handles 502 and 505 and the anchor point 401 are not automatically made equidistant, the adjustment of the first drag point handle 502 may cause the adjustment of a first characteristic, and the adjustment of the second drag point handle 505 may cause the adjustment of a second characteristic.
Alternatively, the magnitude of the characteristic adjustment may be determined by a change in length of the connecting lines 506 or 507, by the speed in which the drag point handles are moved, or by the relative position of the drag point handles before and after the movement. For example, if the connecting line 506 is one distance unit long before the adjustment and four distance units long after the adjustment, the characteristic adjustment may be a factor-of-three characteristic adjustment, based on the absolute change in distance, or a factor-of-four characteristic adjustment, based on the relative change in distance. Distances between other components of the characteristic adjustment control 501, such as a distance between drag point handles, a distance between the drag point handle and the anchor point 401, a total length of the connecting lines, or other distances may be used as the basis for the magnitude adjustment.
Adjusting the paint stroke characteristic at the anchor point 401 may further include adjusting the paint stroke characteristic at the anchor point 501 and at least one adjacent point adjacent to the anchor point based on the user input (received at S110). For instance, a user may wish to alter the width of a paint stroke at a portion of the paint stroke centered around the anchor point 401. In this case, and based on a fall-off value, the characteristic adjustment may be wholly or partially applied to the paint stroke at points adjacent to the anchor point 401. The fall-off value allows a user to select the rate at which a characteristic change is ramped up, or blended with surrounding points. For example, a high fall-off value may manifest itself as a drastic change in the characteristic, affecting points very near to the anchor point 401, while a small fall-off value may manifest itself as an insubstantial change in the characteristic, affecting points distal to the anchor point 401. A user may also wish to change a characteristic at the location of the anchor point 401 alone, in which case the fall-off value is not used.
Since each of the characteristics assist to defines the look of the paint stroke, direct adjustment via a characteristic adjustment control allows the user to use a creative process, rather than an iterative, menu-driven process to alter the paint stroke. This approach realizes many of the advantages of the digital medium, and allows the user to have an experience that is much closer to the adjustment of a physical paint stroke. Since the characteristics of each paint stroke are immutable, and since other editing processes are so tedious, the user no longer has to redraw the paint stroke order to conform the stroke to an original creative intent. Instead, the user is permitted to directly adjust characteristics of a paint stroke properties on screen and in-context after the stroke has been drawn, in an efficient and intuitive manor.
A user input may be received (S116). If the user input (received at S116) selects the anchor point 401 (S117), the anchor point 401 may be deleted (S119), thereby ending the process 100 (S120). The user input (at S117) may be a combination of a mouse down event on the anchor point 401 to select the anchor point 401 and a depression of the DELETE key on a keypad.
If the user input (received at S117) selects a different point on the path 206, an additional anchor point is defined on the path (S121), and a characteristic of the paint stroke is adjusted at the additional anchor point based on the prior user input (received at S110). The ability to select and define additional anchor points after the earlier adjustment of an anchor point effectuates a cut-and-paste functionality, in which a prior anchor point characteristic adjustment is repeated for different anchor points.
Taking the
Although user input is generally described above in the context of a series of mouse events, in other example implementations, key-based input is used to adjust anchor points. With an anchor point defined, the left and right keys could provide a nudge-like behavior to translate the anchor point. Furthermore, the up and down keys could be used to adjust the characteristic of the paint stroke at the anchor point. Using key-based input, accelerators may be used when translating the anchor point along the path, to allow fine, precise control of the location of the anchor point on the path 206.
Additionally, although the process 100 refers to different user inputs, these user inputs may be defined according to desired user input schemes. For example, a traditional user input scheme may be based on a user separately selecting (via separate mouse clicks) the anchor point, the drag point handle start position, and the drag point handle end position. Another, streamlined user input approach may allow the user to select the anchor point by a mouse down event, automatically select the drag point handle start position, and select the drag point handle end position by a mouse up event. Or other custom schemes may also be used. Table 1, below, illustrates some of the differences between the traditional and streamlined approaches.
Using the streamlined input scheme, the mousing experience is brief, but forthright and responsive. Specifically, the user could select both the anchor point and the intensity all in one continuous mousing stream. The point could thus be defined upon the occurrence of a mouse down event, the intensity could be varied by way of a mouse drag event, and the characteristic adjustment would be registered or completed upon the occurrence of a mouse up event. Further alterations to the intensity characteristic could be applied by selecting and dragging the handle in a separate mousing steam, using a mouse-down event and a mouse drag event, to further refine the characteristic value.
Unlike the characteristic adjustment control 501, however, the first drag point handle 1404 further includes a first drag point sub-handle 1409 and a second drag point sub-handle 1410, which extend from the first drag point handle 1404 along an axis perpendicular to the axis defined by the adjustable connecting lines 1406 and 1407. The first drag point sub-handle 1409 and the second drag point sub-handle 1410 are connected to the first drag point handle 1404 by adjustable connecting lines 1411 and 1412, respectively. When adjusted, the first drag point sub-handle 1409 and the second drag point sub-handle 1410 remain equidistant from the first drag point handle 1404.
The second drag point handle 1405 includes similar components corresponding to the first drag point handle 1404, including a third drag point sub-handle 1414 and a fourth drag point sub-handle 1415, connected to the second drag point handle 1405 by way of adjustable connecting lines 1416 and 1417, respectively. The components of third and fourth drag point sub-handles mirror the position and function of the first and second drag point sub-handles, respectively.
Before, after, or during the adjustment of the first or second drag point handles 1405, the user may also adjust a second characteristic by adjusting the drag point sub-handles. For instance, the user may adjust the position of the first drag point handle 1404 to affect the width of the paint stroke at the anchor point, and adjust the position of the second drag point sub-handle 1410 to affect the fall-off value.
When the anchor point 1709 is selected with the cursor 301 (
The characteristic adjustment control 1901 includes the shaped marker 1710 rendered above an anchor point 1709, a first drag point handle 1902, and a second drag point handle 1904. The first drag point handle 1902 and the second drag point handle 1904 are connected to the shaped marker 1710 by adjustable connecting lines 1905 and 1906, respectively, which lengthen and contract to contact the shaped marker 1710 and the drag point handles, as the drag point handles are adjusted.
The first drag point handle 1404 further includes first drag point sub-handle 1907 and second drag point sub-handle 1909, which extend from the first drag point handle 1902 along an axis perpendicular to the axis defined by the adjustable connecting lines 1905 and 1906. The first drag point sub-handle 1907 and the second drag point sub-handle 1909 are connected to the first drag point handle 1902 by adjustable connecting lines 1910 and 1911, respectively. When adjusted, the first drag point sub-handle 1907 and second drag point sub-handle 1909 remain equidistant from the first drag point handle 1902.
The second drag point handle 1904 includes third and fourth drag point sub-handles which mirror the position of the first drag point sub-handle 1907 and second drag point sub-handle 1909, respectively, when adjusted. The user may alter a first characteristic of the paint stroke 1701 by adjusting either or both of first drag point handle 1902 and second drag point handle 1904, and may alter a second characteristic of the paint stroke 1701 by adjusting any or all of the first through fourth drag point sub-handles.
Before, after, or during the dragging operation of the first or second drag point handles 1902 and 1904, the user may also adjust a fall-off characteristic by adjusting one or more of the drag point sub-handles. For instance, the user may adjust the position of the first drag point handle 1902 to affect the jitter characteristic of the of the paint stroke sub-elements centered around at the anchor point, and adjust the position of the second drag point sub-handle 1909 to affect the fall-off characteristic of the paint stroke sub-elements value. As indicated above-fall-off refers to the affect that a width or jitter adjustment at an anchor point affects adjacent points surrounding the anchor point.
As shown in

While
A number of implementations have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure. Accordingly, other implementations are within the scope of the following claims.
