It is known to those skilled in the art that, with the evolution of data processing and the emergence of new business scenarios, the technical solutions provided by the present application are also applicable to similar technical problems.

[0036] The scheme provided by the embodiments of the present application is specifically described by the following embodiments. It should be noted that the order of the following embodiments is not limited as the preferred order of the embodiments.

[0037] The embodiment will be described from the perspective of a model processing apparatus, which can be integrated in an electronic device, which can be a terminal and / or a server, without limitation.

[0038] Please refer to Figure 2 , Figure 2 is a flowchart of a model processing method provided by an embodiment of the present application. The model processing method comprises:

[0039] In step 101, in response to a scaling operation on a target model, first position information to which a specified position of the target model needs to be scaled is determined.

[0040] The target model can be a scalable model, for example, a guardrail model, a race track model, a bench model, a table model, etc., such as a guardrail model on both sides of a race track. The scaling operation can be an operation of scaling the target model. The specified position can be a specified position in the target model, which can be used as a reference position for scaling the target model to control scaling of the target model. The first position information can indicate a position to which the specified position of the target model needs to be moved based on scaling of the scaling operation.

[0041] Optionally, the specified position can include an edge position or a center position of the target model. The edge position can be a most edge position on both sides of the target model, and the center position can be a position of the center of the target model. Whether the specified position is an edge position or a center position of the target model can be set according to actual scaling of the model, for example, when it is needed to keep areas on both sides of the target model after scaling from being scaled, the specified position can be set as an edge position of the target model, when it is needed to keep a middle area of the target model after scaling from being scaled, the specified position can be set as a center position of the target model, etc.

[0042] For example, taking the target model as a guardrail model as an example, please refer to Figure 3a , Figure 3a is a model diagram of a model processing method provided by an embodiment of the present application. It is assumed that a length of the target model is 1 meter (meter, abbreviated as m), and it is assumed that a center position of the target model is located on a world coordinate origin (0, 0, 0), then a distance between the edge position and the center position of the target model is 0.5 m.

[0043] The first position information to which the specified position of the target model needs to be scaled can be determined in various ways in response to the scaling operation on the target model. For example, if the scaling operation is an operation of scaling the target model by dragging one side of the target model by the player, the position to which the specified position of the target model needs to be scaled can be determined according to the end position of the scaling operation. The scaling operation can also be an operation of scaling the track or other model by the player, and triggering the scaling operation on the target model associated with the other model, so that the position to which the specified position of the target model needs to be scaled can be determined based on the scaling of the other model. Alternatively, the scaling operation can also be an operation of adjusting the distribution density of the target model by the player, triggering the scaling operation on the target model, so that the position to which the specified position of the target model needs to be scaled can be determined according to the distribution density of the target model, and the first position information is obtained.

[0044] In step 102, vertex color information of a vertex in the target model is obtained.

[0045] The vertex color information can include a first channel value and a second channel value. The first channel value can indicate a same first distance that the vertex needs to maintain before and after scaling with the specified position. The second channel value can indicate a tiling mode configured for the vertex.

[0046] The vertex color information can be information indicating a vertex color attribute of the vertex. The vertex color attribute can be a material attribute of a vertex color of the vertex. The vertex color can include channel values of three channels (RGB). The first channel value can be a channel value of an R channel. The second channel value can be a channel value of a G channel. The third channel value can be a channel value of a B channel. The first channel value can be a value of a first distance. The first distance can be a distance between the vertex and the specified position in the target model. The vertex and the specified position always maintain the distance when the target model is scaled. The second channel value can be a value indicating a tiling mode configured for the current vertex. For example, a value 255 can be used to indicate that the current vertex is configured in a first tiling mode, and a value 0 can be used to indicate that the current vertex is configured in a second tiling mode. When the second channel value of the vertex is 255, it can indicate that the vertex is configured in the first tiling mode. When the second channel value of the vertex is 0, it can indicate that the vertex is configured in the second tiling mode. The first tiling mode can be a mode of tiling a texture according to a texture tiling rate calculated based on the scaling operation. The second tiling mode can be a mode of tiling the texture according to a texture tiling rate of 1. The texture tiling rate can refer to the number of times a texture image is repeated on a material surface of a model in a texture mapping process. It can determine the size of the area covered by the texture image on the material surface. When the texture tiling rate is 1, it can mean that the texture image is repeated only once.

[0047] For the configuration of the first channel value, taking the guardrail model as the target model and the edge position as the specified position as an example, it is assumed that the distance from the center position of the guardrail model to the edge position is 0.5 m, and the first channel value of the guardrail model is calculated based on the edge positions on the left and right sides of the guardrail model. Specifically, the length range 0-0.5 on each side can be mapped to the calculation range 0-255 of the color, so that the difference between the vertex and the specified position, that is, the first distance, can be mapped to 0-255 as the vertex color of the vertex, so that when the first distance corresponding to the vertex is obtained based on the first channel value, the first channel value is 255, and the first distance corresponding to the vertex is obtained.

[0048] Optionally, there can be various ways to configure the vertex color information of the vertex in the target model, for example, refer to Figure 3b , Figure 3b is a vertex color configuration diagram of a model processing method provided by an embodiment of the present application. The vertex color information of the vertex of the target model can be configured by using the vertex color tool provided by a three-dimensional graphics software, which can be a digital content generation application (DCC). For example, the first distance between the vertex in the target model and the specified position in the target model can be calculated, the first distance is set as the value of the R channel of the vertex color of the vertex, to obtain the first channel value. According to the scaling requirement of the target model, it can be determined that each vertex in the target model belongs to a scaling region, so that the texture tiling mode of the vertex can be determined, the value of the G channel of the vertex color of the vertex is set as the value corresponding to the texture tiling mode corresponding to the vertex, to obtain the second channel value. Whether the texture corresponding to the vertex needs to be configured to have a scrolling effect, the value of the B channel of the vertex color of the vertex can be set. For example, if the texture corresponding to the vertex needs to be configured to have a scrolling effect, the value of the B channel of the vertex color of the vertex can be set as 255, and if the texture corresponding to the vertex does not need to be configured to have a scrolling effect, the value of the B channel of the vertex color of the vertex can be set as 0, to obtain the third channel value.

[0049] In an embodiment, please continue to refer to Figure 3a , it is assumed that there is a vertex at a position 0.35 m away from the center position of the target model, and it is assumed that the specified position is the edge position of the target model, so the first distance between the vertex and the specified position is 0.5-0.35=0.15 m, and the value corresponding to the first distance is assigned to the first channel corresponding to the vertex, to obtain the first channel value.

[0050] In step 103, based on the first distance and the first position information, the second position information of the vertex in the target model that needs to be scaled based on the scaling operation is calculated.

[0051] The second position information can be a position to which a vertex in the target model needs to be scaled based on the scaling operation.

[0052] The second position information to which the vertex in the target model needs to be scaled based on the scaling operation can be calculated in various ways based on the first distance and the first position information. For example, a coordinate value corresponding to the scaling direction of the scaling operation in the first position information can be obtained; a scaling coordinate value can be calculated based on the coordinate value and the first distance; and the second position information to which the vertex needs to be scaled based on the scaling operation can be obtained based on the scaling coordinate value and the initial position information of the vertex.

[0053] The scaling direction can be a direction in which the target model is scaled. For example, please continue to refer to Figure 3a When the target model is scaled in the horizontal direction, the scaling direction can be the x direction. The coordinate value can be a value corresponding to the scaling direction of the scaling operation in the first position information. For example, assuming that the first position information is (1, 0, 0), and the target model is scaled in the horizontal direction, the coordinate value is the x component of (1, 0, 0), that is, 1. The scaling coordinate value can be a position to which the vertex should be scaled in the scaling direction. For example, assuming that the specified position is an edge position, when the coordinate value is positive, the scaling coordinate value can be the difference between the coordinate value and the first distance, and when the coordinate value is negative, the scaling coordinate value can be the sum of the coordinate value and the first distance. It should be noted that the calculation of the scaling coordinate value is used to make the distance between the scaled position of the vertex and the specified position of the target model remain the first distance, and the specific calculation method can be adjusted according to actual conditions, which is not limited in the embodiments of the present application. The initial position information can be the position information of the vertex before scaling.

[0054] The second position information to which the vertex needs to be scaled based on the scaling operation can be obtained in various ways based on the scaling coordinate value and the initial position information of the vertex. For example, the coordinate value corresponding to the scaling direction in the initial position information of the vertex can be replaced by the scaling coordinate value, so as to obtain the second position information to which the vertex needs to be scaled based on the scaling operation. For example, assuming that the initial position information of a vertex a in the target model is (0.3, 1, 1), the scaling direction is the horizontal direction, and the scaling coordinate value is 0.8, the second position information of the vertex a is (0.8, 1, 1).

[0055] In step 104, if the second channel value indicates that the vertex is configured in the first tiling mode, the texture tiling rate of the vertex is determined based on the initial position information of the vertex before scaling, the second position information, and the second channel value, otherwise the texture tiling rate of the vertex is determined to be 1.

[0056] The first tiling mode can be a mode of texture tiling according to a texture tiling rate calculated based on the scaling operation. The texture tiling rate can refer to the number of times a texture image is repeatedly laid on the material surface of a model in the texture mapping process. It can determine the size of the area covered by the texture image on the material surface. When the texture tiling rate is 1, it can mean that the texture image is only repeated once. The texture image can be an image including a texture. Therefore, if the texture tiling rate is 1 when the target model is scaled, the texture tiled on the target model after scaling will have a stretching effect, for example, the texture in the positive direction will be stretched into a rectangle, etc., resulting in poor model scaling effect. To this end, based on the model scaling effect, the embodiments of the present application configure the corresponding texture tiling mode for each vertex through vertex color information configuration, so that based on the scaling effect corresponding to each vertex, the vertex configured with the scaling effect can be tiled with the texture based on the calculated texture tiling rate, and the adaptive texture tiling based on the scaling operation is performed, thereby avoiding the stretching of the texture. For the vertex not configured with the scaling effect, the preset texture tiling rate of 1 can be used for texture tiling, so that the target model can be adaptively scaled and adaptively tiled with the texture based on the scaling operation, effectively improving the model scaling effect.

[0057] If the second channel value indicates that the vertex is configured with the first tiling mode, the texture tiling rate of the vertex is determined based on the initial position information of the vertex before scaling, the second position information, and the second channel value. Otherwise, the texture tiling rate of the vertex is determined to be 1. There can be multiple ways to determine the texture tiling rate of the vertex, for example, the initial position information of the vertex before scaling of the target model can be obtained; based on the second position information and the initial position information corresponding to the vertex, the scaling multiple corresponding to the scaling operation is calculated; and based on the second channel value and the scaling multiple, the texture tiling rate corresponding to the vertex is determined. If the second channel value indicates that the vertex is configured with the first tiling mode, the texture tiling rate of the vertex is determined to be the scaling multiple. Otherwise, the texture tiling rate of the vertex is determined to be 1.

[0058] The scaling multiple can be a multiple of scaling the scalable region in the target model. The edge of the scalable region in the target model is configured with a vertex, and the interior of the scalable region is generally not provided with a vertex. Therefore, when the target model is scaled, the target model can be scaled while the distance between the vertex and the specified position remains unchanged.

[0059] There can be multiple ways to calculate the scaling multiple corresponding to the scaling operation based on the second position information and the initial position information corresponding to the vertex, for example, the coordinate values corresponding to the scaling direction in the second position information and the initial position information of the vertex can be obtained, and the coordinate value corresponding to the second position information is divided by the coordinate value corresponding to the initial position information to obtain the scaling multiple corresponding to the scaling operation.

[0060] The manner of determining the texture tiling rate corresponding to the vertex based on the second channel value and the scaling multiple can be various, for example, the second channel value in the vertex color information of the vertex can include a first value or a second value, the first value can indicate that the vertex is configured in the first tiling mode, and the second value can indicate that the vertex is configured in the second tiling mode, and in this way, a texture tiling rate determination function can be obtained; the texture tiling rate corresponding to the vertex is determined based on the second channel value and the scaling multiple through the texture tiling rate determination function, wherein if the second channel value is the first value, the texture tiling rate corresponding to the vertex is determined as the scaling multiple, and if the second channel value is the second value, the texture tiling rate corresponding to the vertex is determined as 1.

[0061] The first tiling mode can be a mode of tiling the texture according to the texture tiling rate calculated by the scaling operation, and the second tiling mode can be a mode of tiling the texture with the texture tiling rate being 1. The texture tiling rate determination function can be a function for determining the texture tiling rate corresponding to the vertex, for example, can be an interpolation function (Lerp), the first value can be 255, and the second value can be 0, or the first value can be 1, and the second value can be 0, etc., which can be set according to actual conditions.

[0062] The manner of determining the texture tiling rate corresponding to the vertex based on the second channel value and the scaling multiple through the texture tiling rate determination function can be various, for example, the following formula can be used to determine the texture tiling rate corresponding to the vertex through the texture tiling rate determination function:

[0063] uvScale.x=lerp(1,calcuTiling,vertexcolor.g)

[0064] wherein lerp() is an interpolation function, i.e., a texture tiling rate determination function, uvScale.x represents the texture tiling rate of the vertex, calcuTiling is the scaling multiple, and vertexcolor.g is the value of the vertex in the G channel of the vertex color, i.e., the second channel value.

[0065] In step 105, the texture UV information of the vertex of the target model is adjusted based on the texture tiling rate to obtain first target texture UV information.

[0066] The texture UV information can be a texture map coordinate of the target model, also referred to as a UV of the model, which can define the position of each point on a texture image, and the points are associated with the three-dimensional model to determine the position of the surface texture map. The UV is to accurately correspond each point on the texture image to the surface of the three-dimensional model, and the image is smoothly interpolated between the points. The first target texture UV information can be texture UV information adjusted based on the texture tiling rate.

[0067] The method of adjusting the texture UV information of the vertex of the target model based on the texture tiling rate to obtain the first target texture UV information can be various, for example, the texture UV information corresponding to the vertex of the target model can be obtained; the product of the texture UV information corresponding to the vertex and the texture tiling rate is calculated to obtain the first target texture UV information corresponding to the vertex.

[0068] The method of calculating the product of the texture UV information corresponding to the vertex and the texture tiling rate to obtain the first target texture UV information corresponding to the vertex can be various, for example, the first target texture UV information corresponding to the vertex can be calculated by using the following formula:

[0069] OUT.TexCoord.xy=(IN.TexCoord.xy)*(uvScale)

[0070] Wherein, OUT.TexCoord.xy represents the first target texture UV information of the vertex, IN.TexCoord.xy represents the texture UV information corresponding to the vertex, and uvScale represents the texture tiling rate corresponding to the vertex.

[0071] In step 106, the target model is rendered based on the first target texture UV information and the second position information to obtain a scaled target model.

[0072] The scaled target model can be a target model scaled based on a scaling operation. In the scaled target model, the target model is scaled in at least a partial region based on the scaling operation, and in the scaled region, the texture of the model is adapted to the size of the model, so that there is no stretching effect. For example, please refer to Figure 4 , Figure 4 is a model scaling effect schematic diagram of a model processing method provided by the embodiment of the present application. In the scaled target model, only the middle region of the target model can be scaled, and the texture laid in the scaled region of the target model is adaptively tiled with the model scaling, so that there is no stretching effect, effectively improving the model scaling effect.

[0073] Optionally, the texture laid on the target model can also be scrolled to achieve a specific effect. Specifically, an offset parameter can be obtained, the value of the offset parameter changes over time, and based on the first target texture UV information and the offset parameter, the second target texture UV information of the vertex is determined.

[0074] Correspondingly, for the step of rendering the target model based on the first target texture UV information and the second position information to obtain the scaled target model, the step can include: rendering the target model based on the second target texture UV information and the second position information to obtain the scaled target model, and the texture on the target model changes in scrolling.

[0075] Among them, the offset parameter can be a parameter for offsetting the first target texture UV information corresponding to the vertex, that is, a parameter for realizing UV scrolling, and the second target texture UV information can be texture UV information for controlling the texture in the target model to have a texture scrolling effect.

[0076] Among them, the way to obtain the offset parameter can be various, for example, a time function and a scrolling rate control parameter can be obtained, the time function can be used to obtain the game time, and the scrolling rate control parameter can be used to control the texture scrolling rate, for example, the offset parameter can be represented as GameTime*T, wherein GameTime can represent the time function, and T can represent the scrolling rate control parameter. The specific value of T can be set according to actual needs, for example, it can be 0.02, 0.01, etc.

[0077] Among them, the way to determine the second target texture UV information of the vertex based on the first target texture UV information and the offset parameter can be various, for example, the second target texture UV information of the vertex can be determined by using the following formula:

[0078] OUT2.TexCoord.xy=OUT1.TexCoord.xy+GameTime*T

[0079] Among them, OUT2.TexCoord.xy can represent the second target texture UV information corresponding to the vertex, OUT1.TexCoord.xy can represent the first target texture UV information corresponding to the vertex, and GameTime*T can represent the offset parameter.

[0080] Optionally, the manner of determining the second target texture UV information of the vertex based on the first target texture UV information and the offset parameter can also be various, for example, the vertex color information of the vertex can further include a third channel value, which can indicate whether the vertex is configured with a texture scrolling effect, for example, when the third channel value of the vertex is a third numerical value, it can indicate that the vertex is configured with a texture scrolling effect, and when the third channel value of the vertex is a fourth numerical value, it can indicate that the vertex is configured without a texture scrolling effect, the third numerical value and the fourth numerical value are different, for example, the third numerical value can be 255, and the fourth numerical value can be 0, and specific numerical values can be set according to actual conditions, which are not limited in the embodiment of the present application. In this way, the texture scrolling effect of at least part of the region of the target model can be controlled according to the third channel value of the vertex, and the texture scrolling effect is improved.

[0081] Specifically, whether the vertex is configured with a texture scrolling effect can be determined based on the third channel value of the vertex; if the vertex is configured with a texture scrolling effect, the first target texture UV information and the offset parameter of the vertex are summed to obtain the second target texture UV information of the vertex; if the vertex is not configured with a texture scrolling effect, the first target texture UV information of the vertex is determined as the second target texture UV information of the vertex.

[0082] In this way, when the vertex is configured with a texture scrolling effect, the first target texture UV information and the offset parameter of the vertex are summed, so that the second target texture UV information of the vertex is texture UV information that changes based on time, that is, the texture UV information corresponding to the vertex is UV scrolled with time, so that different texture pixels can be sampled based on the changed second target texture UV information, and thus the texture scrolling effect can be constructed, and the texture scrolling of the target model is realized.

[0083] In some racing games, there is a user-generated content (UGC) based subdivision gameplay, players can create track models by themselves, customize length, width and other attributes to give players higher creative freedom in track design, and the track's guardrail model and other decoration models also need to adapt to the change of track size, therefore, when scaling the track or guardrail model, the model and texture need to be reasonably scaled according to the size of the scaling. In the existing model processing method, the texture stretching change after the model size change is often realized through the tri-planar texture mapping technology. However, this method needs to perform rendering in multiple directions, which means that color and lighting calculation will be repeatedly calculated, and multiple rendering brings performance problems, making the model scaling efficiency poor. Therefore, the embodiment of the present application provides a model processing method based on adaptive algorithm of UGC scaling model, by configuring the vertex color information of the vertex based on the model scaling effect, the corresponding texture tiling mode and the first distance from the specified position are configured for each vertex, so that the position to which each vertex needs to be scaled can be determined based on the first distance, and based on the scaling effect corresponding to each vertex, for the vertex configured with the scaling effect, texture tiling can be performed based on the calculated texture tiling rate, adaptive texture tiling based on scaling operation, so as to avoid the situation that the texture is stretched, and for the vertex not configured with the scaling effect, the preset texture tiling rate of 1 can be used for texture tiling, so that the target model can be adaptively scaled and texture adaptively tiled based on the scaling operation, so that the player can dynamically change the size of the model in the UGC mode of the game, while the corresponding texture and model edge locking structure remain unchanged, effectively improving the model scaling effect.

[0084] From the above, the embodiment of the present application determines the first position information to which the specified position of the target model needs to be scaled in response to the scaling operation for the target model; obtains the vertex color information of the vertex in the target model, the vertex color information including a first channel value and a second channel value, the first channel value indicating that the vertex needs to maintain the same first distance with the specified position before and after scaling, and the second channel value indicating the tiling mode configured for the vertex; calculates the second position information to which the vertex in the target model needs to be scaled based on the scaling operation based on the first distance and the first position information; if the second channel value indicates that the vertex is configured in the first tiling mode, determines the texture tiling rate of the vertex based on the initial position information of the vertex before scaling, the second position information and the second channel value, otherwise determines the texture tiling rate of the vertex as 1; adjusts the texture UV information of the vertex of the target model based on the texture tiling rate to obtain first target texture UV information; and renders the target model based on the first target texture UV information and the second position information to obtain the scaled target model. In this way, by determining the first distance that the vertex in the target model needs to maintain with the specified position before and after scaling and the tiling mode configured for the vertex according to the vertex color information of the vertex in the target model, the second position information to which the vertex in the target model needs to be scaled is calculated according to the first distance and the position to which the specified position of the target model needs to be scaled after scaling, and the texture tiling rate of the vertex is determined according to the tiling mode configured for the vertex, and the original texture UV information is adjusted to obtain the first target texture UV information. In this way, based on the second position information of the vertex, the position to which the vertex in the target model needs to be moved based on the scaling operation can be determined, based on the first target texture UV information, adaptive texture tiling can be performed on the region that needs to be scaled based on the texture tiling rate, so as to avoid stretching the texture of the model in the scaling process. In this way, based on the first target texture UV information and the second position information, the target model can be rendered to obtain the scaled target model that is adaptively scaled and the texture of which is not stretched, thereby avoiding the performance problem caused by implementing the model scaling effect through multiple rendering, and effectively improving the model scaling efficiency.

[0122] In the embodiments of the present application, the processor 301 in the electronic device 300 will load the instructions corresponding to the processes of one or more application programs into the memory 302, and run the application programs stored in the memory 302 by the processor 301, thereby realizing various functions according to the following steps:

[0123] In response to the scaling operation on the target model, the first position information to which the specified position of the target model needs to be scaled is determined;

[0124] The vertex color information of the vertex in the target model is obtained, and the vertex color information includes a first channel value and a second channel value. The first channel value indicates that the vertex needs to maintain the same first distance before and after scaling with the specified position, and the second channel value indicates the tiling mode configured for the vertex;

[0125] Based on the first distance and the first position information, the second position information to which the vertex in the target model needs to be scaled based on the scaling operation is calculated;

[0126] If the second channel value indicates that the vertex is configured in the first tiling mode, the texture tiling rate of the vertex is determined based on the initial position information of the vertex before scaling, the second position information, and the second channel value, otherwise the texture tiling rate of the vertex is determined as 1;

[0128] The target model is rendered based on the first target texture UV information and the second position information to obtain the scaled target model.

[0129] This solution can determine the first position information to which a specified position of the target model needs to be scaled in response to a scaling operation on the target model; obtain the vertex color information of the vertices in the target model, which includes a first channel value and a second channel value. The first channel value indicates the same first distance that the vertex and the specified position need to maintain before and after scaling, and the second channel value indicates the tiling mode configured for the vertex; calculate the second position information to which the vertices in the target model need to be scaled based on the first distance and the first position information; if the second channel value indicates that the vertex is configured in the first tiling mode, determine the texture tiling rate of the vertex based on the initial position information of the vertex before scaling, the second position information, and the second channel value; otherwise, determine the texture tiling rate of the vertex to be 1; adjust the texture UV information of the vertices of the target model based on the texture tiling rate to obtain the first target texture UV information; render the target model based on the first target texture UV information and the second position information to obtain the scaled target model. Therefore, by determining the first distance that the vertex in the target model needs to maintain before and after scaling, and the tiling mode configured for the vertex, based on the vertex color information of the vertex in the target model, the second position information that the vertex in the target model needs to be scaled to is calculated based on the first distance and the position that the specified position in the target model needs to be scaled to after scaling. Based on the tiling mode configured for the vertex, the texture tiling rate of the vertex is determined and the original texture UV information is adjusted to obtain the first target texture UV information. Based on the second position information of the vertex, the position that the vertex in the target model needs to move to based on the scaling operation can be determined. Based on the first target texture UV information, the texture tiling of the area to be scaled can be adaptively performed based on the texture tiling rate, avoiding stretching of the model texture during scaling. Rendering the target model based on the first target texture UV information and the second position information can obtain a scaled target model that is adaptively scaled based on the scaling operation and whose texture is not stretched, avoiding the performance problems caused by achieving the model scaling effect through multiple renderings, and thus effectively improving the model scaling efficiency.
