Patent Application
20250041727
The present disclosure relates to the field of computer technology, and in particular, to a method and apparatus for preventing model penetration, an electronic device, and a storage medium.
In 3D games, it often occurs that the inner layer clothing of the character model penetrates into the outside of the outer layer clothing, or the skin of the character penetrates into the outside of the clothing, resulting in a damage to the game quality and poor user experience.
In order to prevent penetration of clothing of the character model, there are generally two ways in the related art. The first manner is to maintain reasonable distances between the clothing and the character body, or between the outer-layer clothing and the inner-layer clothing, by adjusting the physical parameters of the clothing and the character body as well as the outer-layer clothing and the inner-layer clothing.
A method for preventing model penetration, including:
An electronic device, including a processor, a memory, and a computer program stored on the memory and capable of running on the processor; where, when the computer program is executed by the processor, the steps of the above method for preventing model penetration are implemented.
A computer-readable storage medium, with a computer program stored thereon; and when the computer program is executed by a processor, the steps of the above method for preventing model penetration are implemented.
In order to illustrate the technical solutions of the present disclosure more clearly, the accompanying drawings that need to be used in the description of the present disclosure are briefly described below. Obviously, the drawings in the following description are some embodiments of the present disclosure, and for those of ordinary skill in the art, other drawings can also be obtained from these drawings without creative efforts.
In order to make the above objectives, features and advantages of the present disclosure more obvious and comprehensible, the present disclosure will be further described in detail below with reference to the accompanying drawings and specific implementations. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present disclosure shall fall within the protection scope of the present disclosure.
In 3D games, in order to simulate the dynamic effect of clothing in reality, physical modes such as a cloth system or a rigid body driving skeletons, are usually used to drive the movement of the clothing grid. In the game, there is a strict requirement for the running time of each frame. Usually, for a game of 60 frames, the running time of each frame is 16.6 ms, and the time allocated to the physical simulation is less. In such a short period of time, accurate physical simulation is difficult to achieve. Therefore, it often occurs that the inner-layer clothing penetrates into the outer-layer clothing, and the skin of the character penetrates into the outside of the clothing.
In the related art, there are generally two ways to prevent model penetration. The first manner is to maintain reasonable distances between the clothing and the character body, or between the outer-layer clothing and the inner-layer clothing, by adjusting the physical parameters of the clothing and the character body as well as the outer-layer clothing and the inner-layer clothing. However, in this manner, a large amount of time needs to be spent by art production personnel on adjusting the physical parameters, the efficiency is low, and the clothing looks like being stretched out, which results in unreal overall image of the model and serious physical effect loss.
In a second manner, during the model-making stage, the inner-layer clothing grid and the character body grid that are blocked by the outer-layer clothing are marked; and then the marked inner-layer clothing grid and the character body grid are removed during rendering. According to this processing mode, there are very high requirements for the grid selected to be marked; if the marking range is too small, that is, some grids which should be marked are not marked, the penetration phenomenon may still exist; and if the marking range is too large, that is, some grids which are not blocked by the outer-layer clothing are marked, it may result in a fracture phenomenon of the rendered model.
In view of this, the embodiments of the present disclosure provide a method for preventing model penetration to overcome the defects in the related art.
In some embodiments of the present disclosure, the method for preventing model penetration may be performed on a local terminal device or a server. When the method for preventing model penetration is performed on a server, the method for preventing model penetration may be implemented and executed based on a cloud interaction system, where the cloud interaction system includes a server and a client device.
In some embodiments, various cloud applications may be run in the cloud interaction system, such as a cloud game. Taking a cloud game as an example, the cloud game refers to a game manner based on cloud computing. In the running mode of the cloud game, the running body of the game program and the game screen presentation body are separated; the storage and running of the method for preventing model penetration are completed on the cloud game server, and the role of the client device is to receive and send data, and present the game screen. For example, the client device may be a display device with a data transmission function close to the user side, such as a first terminal device, a television, a computer, a palm computer, or the like. However, it is the cloud game server in the cloud to perform the method for preventing model penetration. When a game is performed, the player operates the client device to send an operation instruction to the cloud game server; the cloud game server runs the game according to the operation instruction, encodes and compresses data such as the game screen, returns the data to the cloud client device through the network, and finally decodes and outputs the game screen through the client device.
In some embodiments, taking a cloud game as an example, the local terminal device stores a game program and is configured to present a game screen. The local terminal device is configured to interact with the player through a graphical user interface, that is, to conventionally download and install the game program through the electronic device and run it. The manner in which the local terminal device provides the graphical user interface to the player may include a variety of manners; for example, it may be rendered and displayed on a display screen of the terminal, or it may be provided to the player through holographic projection. For example, the local terminal device may include a display screen and a processor; the display screen is configured to present a graphical user interface; the graphical user interface includes a game screen; the processor is configured to run the game, generate the graphical user interface, and control the display of the graphical user interface on the display screen.

In step 101, a target sub-model of a model to be rendered is determined.
In step 102, the target sub-model is rendered, and a display position of a front pixel point corresponding to the target sub-model is stored into a buffer area.
In step 103, during performing rendering on other sub-models in the model to be rendered except for the target sub-model, a pixel point with a corresponding display position being the same as the display position stored in the buffer area among pixel points corresponding to other sub-models is removed.
In the embodiments of the present disclosure, the target sub-model of the model to be rendered is determined; during performing rendering on the target sub-model, the display position of the front pixel point corresponding to the target sub-model is stored into a buffer area; and during performing rendering on other sub-models in the model to be rendered except for the target sub-model, a pixel point with a corresponding display position being the same as the display position stored in the buffer area among pixel points corresponding to other sub-models is removed, so as to ensure that the part blocked by the target sub-model in other sub-models may not be rendered and displayed, thus simply and efficiently solving the problem of model penetration.
The method for preventing model penetration in the present example embodiment is further described below.
In step 101, a target sub-model of a model to be rendered is determined.
In the embodiments of the present disclosure, the model to be rendered may be a character model that needs to be displayed in real time during the running process of the game application, such as a character model in the game.
The model to be rendered is generally formed by combining a plurality of sub-models. Taking a character model as an example, the character model is generally formed by a body model of a person and a clothing model.
Each sub-model has a corresponding layer level. According to the layer level corresponding to each sub-model, the target sub-model corresponding to the target layer level number may be determined. The target layer level number is generally the maximum layer level number, that is, the target sub-model is the outermost sub-model of the model to be rendered. The target layer level number may be an absolute maximum layer level number, or may be a relative maximum layer level number, the two cases of which will be exemplarily explained in the following context. Generally, during the model production stage, the respective layer levels of the plurality of sub-models forming the model to be rendered may be determined by the art production personnel.
In an example, when determining the layer level of each sub-model, the art production personnel may determine the layer level of each sub-model by taking the center line of the model to be rendered as a reference and according to the maximum vertical distance between each sub-model and the center line.
For example, when the model to be rendered is a character model, the center line of which is a straight line where the midline of the character model is located. If the character model is formed by a body model and a clothing model, the vertical distance between the body model forming the character model and the center line is smaller than the vertical distance between the clothing model and the center line. Therefore, the layer level of the body model is at the innermost layer, the clothing model is at the outermost layer; that is, the body model is the first layer, and the clothing model is the second layer. It can be understood that the target sub-model of the model to be rendered is a sub-model with the maximum vertical distance from the center line of the model to be rendered among the plurality of sub-models forming the model to be rendered; that is, the target sub-model is a sub-model with the maximum layer level number among the sub-models forming the model to be rendered.
For example, when the model to be rendered is a character model wearing a waistcoat, a long-sleeved underwear and a skirt, the waistcoat does not overlap the skirt, and the long-sleeved underwear does not overlap the skirt either, the body model of the character in the model to be rendered is the first layer, the long-sleeved underwear model is the second layer, the waistcoat model is the third layer, and the skirt model is the second layer. It can be seen that in the plurality of sub-models of the model to be rendered, the sub-model corresponding to the absolute maximum layer level number is the waistcoat model. Therefore, in the present example, the waistcoat model is the target sub-model; and the long-sleeved underwear model, the skirt model and the body model belong to other sub-models.
When there is a plurality of sub-models with the maximum layer level number, the plurality of sub-models corresponding to the plurality of maximum layer level number are all the target sub-models. For example, when the model to be rendered is a character model wearing a jacket and a skirt, where the jacket does not overlap with the skirt, in the model to be rendered, the body model of the character is the first layer, the jacket model and the skirt model are both the second layers, which are both the maximum layer levels, and the target sub-models are the jacket model and the skirt model.
In some embodiments, the target sub-model is a sub-model with a layer level number of a maximum layer level number among the sub-models corresponding to the coverage area of the target sub-model. That is, the target layer level number corresponding to the target sub-model is the relative maximum layer level number. It may be understood that in the embodiment, it may be determined whether the sub-model is located at the maximum layer level in the coverage area of the sub-model or not, according to the area (i.e. the coverage area) corresponding to each sub-model; and if yes, the sub-model is determined as the target sub-model.
For example, when the model to be rendered is a character model wearing a waistcoat, a long-sleeved underwear and a skirt, where the waistcoat does not overlap with the skirt, and the long-sleeved underwear does not overlap with the skirt either, in the model to be rendered, the body model of the character is the first layer, the long-sleeved underwear model is the second layer, the waistcoat model is the third layer, and the skirt model is the second layer. For the skirt model, the coverage area of skirt model also relates to the body model, and the body model is the first layer, which is smaller than the layer level number of the skirt model; that is, the skirt model is the sub-model with the maximum layer level number in its coverage area; therefore, the skirt model may be determined as the target sub-model. Similarly, for the waistcoat layer level, the coverage area of the waistcoat layer level relates to the body model and the long-sleeved underwear model, where the body model is the first layer, and the long-sleeved underwear model is the second layer, both of which are smaller than the layer level number of the waistcoat model; that is, the waistcoat model is the sub-model with the maximum layer level number in its coverage area; therefore, the waistcoat model may also be determined as the target sub-model. For the long-sleeved underwear model, the coverage area of the long-sleeved underwear model relates to the body model and the waistcoat model; since the layer level number of the long-sleeved underwear model is smaller than the layer level number of the waistcoat model, that is, the long-sleeved underwear model is not the sub-model with the maximum layer level number in its coverage area, the long-sleeved underwear model is not the target sub-model. That is, in this example, the target sub-model includes the skirt model and the waistcoat model, and the long-sleeved underwear model and the body model belong to other sub-models.
In step 102, the target sub-model is rendered, and a display position of a front pixel point corresponding to the target sub-model is stored into a buffer area.
In the embodiments of the present disclosure, when performing rendering on the model to be rendered, the target sub-model is rendered firstly; and when the target sub-model is rendered, a display position of a front pixel point corresponding to the target sub-model is stored into a buffer area. Among them, the front pixel point refers to a pixel point corresponding to a front surface of the target sub-model; and the front surface generally refers to a surface of the target sub-model that can be directly seen visually when the model to be rendered is normally displayed. In some embodiments, determining whether a surface is a front surface or not, is related to standards set during production of the model according to art. For example, when the model is produced according to art, if points in a polygon (i.e., a surface) appear in a clockwise order, the surface may be set as a front surface; therefore, when points in a surface appear in a clockwise order, the surface is the front surface.
The display position of the front pixel point corresponding to the target sub-model is stored into the buffer area, and is used as a reference for subsequent rendering of other sub-models, preventing the phenomenon that the target sub-model is penetrated due to the fact that the pixel points corresponding to the other sub-models are displayed at the display positions stored in the buffer area.
In some embodiments of the present disclosure, performing rendering on the target sub-model, and storing the display position of the front pixel point corresponding to the target sub-model into the buffer area, includes:
In the embodiments, the back removal rendering refers to, during rendering, removing the back surface of the target sub-model without rendering, and only rendering the front surface of the target sub-model, so as to reduce the number of surfaces to be rendered, thus improving the rendering efficiency. Among them, the back surface generally refers to a surface of the target sub-model that cannot be directly seen visually when the model to be rendered is normally displayed. In some embodiments, determining whether a surface is a back surface or not, is related to rules set during production of the model according to art. For example, when producing the model according to art, if points in a polygon (i.e., a surface) appear in a clockwise order, the surface may be set as a front surface. Therefore, when points in a surface appear in a clockwise order, the surface is a front surface; correspondingly, when points in a surface appear in a counterclockwise order, the surface is the back surface.
Furthermore, in some embodiments of the present disclosure, when the target sub-model represents clothing, performing rendering on the target sub-model, and storing the display position of the front pixel point corresponding to the target sub-model into the buffer area, includes:
When there is a need to view the interior of the clothing, when producing the model that represents the clothing, the art production personnel may use two layers (an inner layer and an outer layer) of grids with the same shape, there is a certain thickness between the two layers of grids, and there is no overlapping and interleaving situation, so that the interior of the clothing may be displayed in a scenario where it is necessary to see the interior of the clothing.
In the embodiments of the present disclosure, when performing rendering on the target sub-model formed by an outer-layer grid and an inner-layer grid, back removal rendering may be performed on the outer-layer grid firstly, so as to reduce the number of surfaces to be rendered; and for the inner-layer grid, direct rendering may be performed, so as to avoid that the inner-layer grid is not rendered due to back-removal rendering when the inner-layer grid needs to be displayed.
In step 103, during performing rendering on other sub-models in the model to be rendered except for the target sub-model, a pixel point with a corresponding display position being the same as the display position stored in the buffer area among pixel points corresponding to other sub-models is removed.
And after rendering of the target sub-model is completed, rendering of other sub-models in the model to be rendered except for the target sub-model is performed. During performing rendering on other sub-models, the pixel point with a corresponding display position being the same as the display position stored in the buffer area among pixel points corresponding to other sub-models is removed, so that only the target sub-model is displayed in the display area for displaying target sub-model, and the phenomenon that other sub-models penetrates into the target sub-model can be prevented.
In a specific implementation, during performing rendering on other sub-models, the display position of each pixel point corresponding to other sub-models can be compared with the display position in the buffer area. When the display position of the pixel point corresponding to other sub-models is different from any display position stored in the buffer area, rendering and writing are performed. When the display position of the pixel point corresponding to other sub-models is the same as one of the display positions stored in the buffer area, rendering and writing are not performed; that is, the pixel point with a corresponding display position being the same as the display position stored in the buffer area among pixel points corresponding to other sub-models is removed.
In some embodiments of the present disclosure, other sub-models may be divided into a first model part and a second model part, where the display positions of the pixel points corresponding to the first model part are always different from the display positions stored in the buffer area. Removing, during performing rendering on other sub-models in the model to be rendered except for the target sub-model, a pixel point with a corresponding display position being the same as a display position stored in the buffer area among pixel points corresponding to other sub-models, may include:
In the embodiment, the other sub-model may be divided into the first model part and the second model part by art production personnel according to experiences, ensuring that the display positions of the pixel points corresponding to the first model part are always different from the display position stored in the buffer area. For example, when the model to be rendered corresponds to a character model wearing a dress, the target sub-model of the model to be rendered is a dress model, and the other sub-model is a body model of the character. Considering that the head of the character may never be blocked by the dress, thus, the body model may be divided into the head part and the other part. The head part is the first model part, and the other part is the second model part. Certainly, it can also be considered that the hands and the feet of the character may also never be blocked by the dress, thus, the body model can be divided into the head part, the hands, the feet and the remaining other part. The head part, the hands and the feet form the first model part, and the remaining other part is the second model part.
Since the display position of the pixel point corresponding to the first model part is always different from the display position stored in the buffer area, the first model part may be directly rendered, so as to reduce the number of pixel points needing to be compared, and improve the rendering efficiency.
According to the embodiment, during performing rendering on the second model part, whether the display position of the pixel point corresponding to the second model part is the same as the display position stored in the buffer area or not is compared; and if yes, the pixel point is removed; therefore, in the embodiment, the division of the first model part and the second model part does not need to be very accurate, which may reduce the difficulty of division by the art production personnel. In the example of the character model with the dress, the first model part may only include the head part of the body model of the character, or may be formed by the head part, the hands and the feet of the body model of the character. It can be seen that the division does not need to be very accurate.
In some embodiments of the present disclosure, when the model to be rendered is formed by more than three sub-models, that is, when the other sub-models include more than two sub-models, removing, during performing rendering on other sub-models in the model to be rendered except for the target sub-model, a pixel point with a corresponding display position being the same as a display position stored in the buffer area among pixel points corresponding to other sub-models, may further include:
In the embodiment, for the model to be rendered formed by a plurality of sub-models, rendering may be sequentially performed according to the order of layer levels of the sub-models from large to small.
For example, when the model to be rendered corresponds to a character model wearing a dress and a waistcoat outside the dress, the first layer level is a body model of the character, the second layer level is a dress model, and the third layer level is a waistcoat model. Thus, the target sub-model of the model to be rendered is the waistcoat model, the other sub-models are the dress model and the body model of the character, and the layer level of the dress model is greater than the layer level of the body model. At this time, after rendering of the waistcoat model is completed, rendering of the dress model may be started. When performing rendering on the dress model, whether the display position of the pixel point corresponding to the dress model is the same as the display position stored in the buffer area or not, is compared; and if yes, the pixel point corresponding to the dress model is removed. After rendering of the dress model is completed, rendering of the body model is then performed. When performing rendering on the body model, whether the display position of the pixel point corresponding to the body model is the same as the display position stored in the buffer area or not, is compared; and if yes, the pixel point corresponding to the body model is removed. It can be ensured that the waistcoat model at the outermost layer cannot be penetrated by the inner layer model.
Furthermore, performing rendering sequentially according to an order of layer levels of the more than two sub-models from large to small, may further include:
Among them, the sub-model at the current layer level may be a sub-model at any layer level. During rendering of the sub-model at the current layer level, the display position of the pixel point corresponding to the sub-model at the current layer level is compared with the display position stored in the buffer area; if they are the same, the pixel point corresponding to the sub-model at the current layer level is removed; and if they are different, the different display position is added into the buffer area. Therefore, during rendering of the sub-model at a next layer level (i.e., the sub-model with a layer level number smaller than the layer level number of the sub-model at the current layer level), it may be determined whether the display position of the pixel point corresponding to the sub-model at the next layer level coincides with the display position of the corresponding pixel point of the sub-model at the layer level that has been previously rendered or not, and the coincident pixel points are removed, so as to prevent the sub-model at a next layer level from penetrating into the previously rendered sub-model.
Continuing to take the character model wearing a dress and a waistcoat outside the dress as an example, the rendering process of the waistcoat model and the dress model is consistent with that described above, and details are not described here again. When rendering of the dress model is completed, the display position of the corresponding pixel point of the dress model is added into the buffer area. At this time, the buffer area stores with the display area of the waistcoat and the display area of the dress not overlapped with the waistcoat. Then, the body model is rendered, and the pixel point with a display position falling within the display area of the waistcoat and display area of the dress not overlapped with the waistcoat among the pixel points corresponding to the body model, is removed, preventing the body model from penetrating outside the dress model or the waistcoat model.
In some embodiments, when sequentially performing rendering according to an order of the layer levels of more than two sub-models from large to small, the sub-model at the current layer level may also be divided into a model outer-part and a model inner-part, where the model outer-part and the model inner-part are relative to the previously rendered sub-model. That is, the sub-model at the current layer level may be divided into a model outer-part which may never be blocked by the rendered sub-model and a model inner-part. In the specific implementation, it may be divided and marked by the art production personnel according to experiences. When the model outer-part of the sub-model at the current layer level is rendered, it may be directly rendered; and when the rendering is completed, the display position of the pixel point corresponding to the model outer-part is stored in the buffer area. When the model inner-part of the sub-model at the current layer level is rendered, the process of comparing with the display position in the buffer area needs to be performed. When rendering of the model inner-part is completed, the display position of the pixel point of the model inner-part which is not removed, is stored in the buffer area.
Furthermore, in some embodiments of the present disclosure, removing, during performing rendering on other sub-models in the model to be rendered except for the target sub-model, a pixel point with a corresponding display position being the same as a display position stored in the buffer area among pixel points corresponding to other sub-models, may further include:
In the embodiment, when performing rendering on other sub-models, the back-removal rendering may be selected to reduce the number of surfaces to be rendered and improve the rendering efficiency.
According to the method for preventing model penetration provided by the embodiments of the present disclosure, the penetration part is corrected from the rendering aspect, solving the problem of model penetration caused by inaccurate physical simulation. Compared with the first manner of adjusting physical parameters by the art production personnel in the related art, in the embodiments of the present disclosure, there is no need to change physical parameters in order to eliminate penetration, thus retaining a better dynamic effect of cloth. Furthermore, a large amount of time for parameter adjustment by the art production personnel can be saved. In addition, compared with the second manner of directly cutting off the model part that is possible to be penetrated, during rendering in the embodiments of the present disclosure, removal of penetration is performed by using a manner of pixel-by-pixel, which is more accurate, and may not result in a goof phenomenon when a cut-off part needs to be displayed. Furthermore, in the embodiments of the present disclosure, the model rendering efficiency may be further improved through an operation in which there is no need to accurately mark a removal part, which does not bring great workload to the art production personnel. According to the embodiments of the present disclosure, the penetration problem may be correctly processed on the premise of ensuring the physical effect of the clothing, the art workload is reduced, and the model rendering efficiency is improved.
In order to facilitate those skilled in the art to understand the present solution, the method for preventing model penetration provided in the embodiments of the present disclosure will be described below with reference to specific examples.
In the example, the model to be rendered corresponds to a character model wearing a dress. The implementation process of the method for preventing model penetration may include two processing stages; the first processing stage is an offline processing stage, and the second processing stage is a running stage. As shown in
In step 201, an outer grid of the target sub-model is determined.
The target sub-model in the example is a dress model. When the dress model is formed by an inner-layer grid and an outer-layer grid, the outer-layer grid of the dress model needs to be determined, and the outer-layer grid of the dress model needs to be stored as a separate material group. When the dress model is only formed by one layer of grid, the grid of the dress model is the outer-layer grid, which is stored as a separate material group.
In step 202, the other sub-model in the model to be rendered except for the target sub-model is divided into a first model part and a second model part, where the display position of the pixel point corresponding to the first model part is always different from the display position stored in the buffer area.
In the example, the other sub-model is the body model, and the body model may be divided into a first model part including a head part, hands and feet, and a remaining second model part by the art production personnel according to experiences, so as to improve the operation efficiency in subsequent running processes.
As shown in
In step 301, back removal rendering is performed on the outer-layer grid of the target sub-model, and the display position corresponding to the pixel point of the rendered outer-layer grid is stored into a first template buffer area.
In the example, a template test is turned on prior to the start of rendering. The template test is a sample by sample operation performed after fragment shader and provided by a 3D graphics pipeline. In the template test, stencil function (a template function) is set to Always passes, stencil Ref (a template reference value) is set to 0x48 (0x48 here is merely an example, which may be any value between 0x01 to 0xff); stencil operation (a template operation value) is set to Replace. After the template test setting is completed, rendering after back removal is performed on the outer-layer grid is performed then. After rendering of the outer-layer grid is completed, the display position of the pixel point corresponding to the outer-layer grid is stored into the 0x48 of the template buffer area.
In step 302, rendering is performed on the inner-layer grid of the target sub-model.
When the target sub-model includes an inner-layer grid, after rendering of the outer-layer grid of the target sub-model is completed, stencil Ref is modified to be 0x16 (0x16 here is merely an example, and may be any value other than 0x48 between 0x01 to 0xff); and then, rendering is performed on the inner-layer grid. After the rendering of the inner-layer grid is completed, the display position of the pixel point corresponding to the inner-layer grid may be stored in 0x16 of the template buffer area.
In step 303, rendering is performed on a second model part of the other sub-model.
In the example, after the rendering of the target sub-model is completed, stencil function needs to be set to Not Equal, stencil Ref is set to 0x48 (which needs to be consistent with the stencil Ref set in step 301), and then rendering is performed on the second model part of the other sub-model. When rendering is performed on the second model part, the second model part may be compared with the display position in the template buffer area. In some embodiments, a value corresponding to the display position is stored in the template buffer area; during comparison, if the value of the display position of the corresponding pixel is equal to the value stored in the template buffer area, the pixel with the same value is removed; and if the value of the display position of the corresponding pixel is not equal to the value stored in the template buffer area, rendering may be performed, and the value of the display position of the pixel is added into the template buffer area.
In step 304, rendering is performed on a first model part of the other sub-model.
Since the first model part is a part that is never blocked by the outer-layer sub-model, before rendering of the first model part, the template test may be turned off. That is, the first model part is directly rendered, and no special processing is required.
In the example, at the offline stage, the outer-layer grid of the target sub-model of the model to be rendered may be separated out, and the other sub-model in the model to be rendered except for the target sub-model may be divided into the first model par that is never blocked by the target sub-model and the remaining second model part. At the running stage, the value of the display position of the pixel point corresponding to the outer-layer grid is stored into a specified template buffer area according to that the outer-layer grid of the target sub-model is rendered firstly, and then rendering is performed on the second model part of the other sub-model; when rendering is performed on the second model part, the pixel with the same value of display position as the value stored in the template buffer area among the pixel points corresponding to the second model part is removed, and finally rendering is performed the first model part of the other sub-model. Alternatively, at the running stage, the first model part of the other sub-model may also be rendered firstly, then the template test is turned on, rendering is performed on the outer-layer grid of the target sub-model, the value of real position of the pixel point corresponding to the outer-layer grid is stored in the specified template buffer area, and finally rendering is performed on the second model part of the other sub-model. When rendering is performed on the second model part, the pixel with the same value of display position as the value stored in the template buffer area among the pixel points corresponding to the second model part is removed. It may effectively prevent model penetration, and compared with the processing manner in the related art, the efficiency is higher, and the effect is better.
It should be noted that, for the method embodiments, for simplicity of description, they are all expressed as series of action combinations; however, those skilled in the art should understand that the embodiments of the present disclosure are not limited by the described action sequence, because some steps may be performed in other sequences or simultaneously according to the embodiments of the present disclosure. Secondly, those skilled in the art should also understand that the embodiments described in the specification are all preferred embodiments, and the involved actions are not necessarily required by the embodiments of the present disclosure.
