[0002] With the continuous development of computer communication technology and the widespread use of terminals such as smartphones, tablets, and laptops, terminals are becoming increasingly diversified and personalized, becoming indispensable in people's lives and work. To satisfy people's pursuit of spiritual enrichment, entertainment games that can be played on these terminals have emerged. For example, games developed based on client or server architecture, such as Multiplayer Online Battle Arena (MOBA) and Massive Multiplayer Online (MMO), are popular due to their high smoothness, good controls, and real-time combat. With the booming development of online games, people's demands for the realism of game scenes are increasing.

[0003] In computer animation production for games, techniques related to detail normals can be used to add textures of various materials to virtual models, such as stitch information for embroidery. However, because the stitches in the same material area of ​​the virtual embroidery model rendered by existing technology are exactly the same, the display effect is rigid and does not conform to the visual experience of real embroidery to users, resulting in low realism of the rendered virtual embroidery model and poor visual experience for users.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] This application provides a method, apparatus, computer device, and storage medium for texture processing of virtual models. Specifically, the texture processing method for virtual models in this application can be executed by a computer device, which can be a terminal or a server. The terminal can be a smartphone, tablet, laptop, touch screen, game console, personal computer (PC), personal digital assistant (PDA), or other terminal device. The terminal can also include a client, which can be a game application client, a browser client carrying a game program, or an instant messaging client. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms.

[0031] For example, when the texture processing method of the virtual model runs on a terminal, the terminal device stores a game application and uses it to render the virtual scene in the game screen. The terminal device is used to interact with the user through a graphical user interface, such as downloading, installing, and running the game application. The terminal device can provide the graphical user interface to the user in various ways, such as rendering it on the terminal device's display screen or presenting the graphical user interface through holographic projection. For example, the terminal device can include a touch screen and a processor. The touch screen is used to present the graphical user interface and receive operation commands generated by the user interacting with the graphical user interface, which includes game screens. The processor is used to run the game, generate the graphical user interface, respond to operation commands, and control the display of the graphical user interface on the touch screen.

[0032] For example, when the texture processing method of the virtual model runs on a server, it can be considered cloud gaming. Cloud gaming refers to a gaming method based on cloud computing. In the cloud gaming operating mode, the main body running the game application and the main body displaying the game screen are separated. The storage and execution of the texture processing method of the virtual model are completed on the cloud gaming server. The game screen display is completed on the cloud gaming client. The cloud gaming client is mainly used for receiving and sending game data and displaying game screens. For example, the cloud gaming client can be a display device with data transmission capabilities close to the user, such as a mobile terminal, television, computer, PDA, personal digital assistant, etc., but the terminal device for processing game data is the cloud gaming server in the cloud. When playing the game, the user operates the cloud gaming client to send operation commands to the cloud gaming server. The cloud gaming server runs the game according to the operation commands, encodes and compresses the game screen and other data, returns it to the cloud gaming client through the network, and finally, the cloud gaming client decodes and outputs the game screen.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of a virtual model texture processing system provided in an embodiment of this application. The system may include at least one terminal, at least one server, at least one database, and a network. A user's terminal can connect to different game servers via the network. The terminal is any device with computing hardware capable of supporting and executing software products corresponding to the game. Furthermore, when the system includes multiple terminals, multiple servers, and multiple networks, different terminals can connect to each other through different networks and servers. The network can be a wireless network or a wired network, such as a wireless local area network (WLAN), local area network (LAN), cellular network, 2G network, 3G network, 4G network, 5G network, etc. Additionally, different terminals can also connect to other terminals or servers using their own Bluetooth networks or hotspot networks. For example, multiple users can connect online through different terminals via appropriate networks and synchronize with each other to support multiplayer games. Furthermore, the system may include multiple databases coupled to different servers, and can continuously store game environment-related information in the databases while different users are playing multiplayer games online.

[0034] It should be noted that, Figure 1The schematic diagram of the virtual model texture processing system shown is merely an example. The virtual model texture processing system and scene described in this application embodiment are for the purpose of more clearly illustrating the technical solutions of this application embodiment and do not constitute a limitation on the technical solutions provided in this application embodiment. As those skilled in the art will know, with the emergence of new business scenarios, the technical solutions provided in this application embodiment are also applicable to similar technical problems.

[0035] To address the aforementioned problems, this application provides a texture processing method, apparatus, computer device, and storage medium for virtual models, which can improve the realism of virtual models displayed in games. These will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments.

[0036] Please see Figure 2 , Figure 2 This is a flowchart illustrating a texture processing method for a virtual model provided in an embodiment of this application. The specific process of the texture processing method for the virtual model can be shown in steps 101 to 106 below:

[0037] 101. Obtain the mask map corresponding to the base normal map of the detail texture to be rendered, wherein the base normal map includes multiple texture regions of the detail texture to be rendered, the non-masked regions of the mask map correspond one-to-one with the texture regions, and the mask brightness values ​​of the non-masked regions are not completely equal, and the detail texture to be rendered is a detail texture set for the target virtual model.

[0038] In order to obtain a mask map that includes multiple non-masked areas with different mask brightness, the method for the step "obtaining the mask map corresponding to the base normal map of the detail texture to be rendered" may include:

[0039] A texture to be processed is obtained, and the texture to be processed is processed based on the texture regions of multiple detail textures to be rendered in the base normal map to obtain a processed texture, wherein the processed texture includes multiple regions to be processed, and the regions to be processed correspond one-to-one with the texture regions.

[0040] A masking brightness value is set for each of the multiple areas to be processed to obtain multiple unmasked areas, wherein the masking brightness values ​​of the unmasked areas are not completely equal.

[0041] A specified mask brightness value is set for other areas besides the multiple areas to be processed to obtain a mask texture, wherein the specified mask brightness value is the mask brightness value that makes the other areas black.

[0042] For example, please see Figure 3Obtain a mask map that is identical to the texture regions of multiple detail textures to be rendered in the base normal map. Each non-masked region in the mask map is set with a non-zero and different mask brightness value. Furthermore, the mask brightness of other masked regions in the mask map is set to 0 so that all regions except the masked regions are displayed as black.

[0043] 102. Obtain the mask brightness value of each pixel in the mask texture, and convert each mask brightness value into texture coordinate rotation information, wherein the texture coordinate transformation information corresponding to different mask brightness values ​​is different.

[0044] In one specific embodiment, the method for the step "obtaining the mask brightness value of each pixel in the mask texture and converting each mask brightness value into texture coordinate rotation information" may include:

[0045] The mask brightness value of each pixel in the mask texture is processed based on the preset angle difference value and the preset angle offset value, and each mask brightness value is converted into texture coordinate rotation information.

[0046] Furthermore, the step "processing the mask brightness value of each pixel in the mask texture based on the preset angle difference value and the preset angle offset value, and converting each mask brightness value into texture coordinate rotation information" can include:

[0047] Obtain the product between the mask brightness value of the pixel and the preset angle difference value;

[0048] The sum of the product and the preset angle offset value is obtained as the provisional rotation value of the pixel.

[0049] The texture coordinate rotation information of the pixel is generated based on the provisional rotation value of the pixel and the preset rotation matrix.

[0050] For example, mask brightness values ​​can be mapped to a UV rotation angle using a calculation formula; this rotation angle is the provisional rotation value. A computer device can convert each mask brightness value into a provisional rotation value according to the rotation value calculation formula, as shown below:

[0051] Angle=MaskBrightness×AngleDiff+AngleBias

[0052] MaskBrightness is the brightness value of the mask for each pixel, AngleDiff is the preset angle difference value, and AngleBias is the preset angle offset value. Both the preset angle difference and preset angle offset values ​​are values ​​that artists can flexibly set according to actual design needs. The preset angle difference value is used to adjust the size of the angle difference between different gray levels, while the preset angle offset value is used to add an overall angle deflection to all rendered areas. Therefore, artists can use these two values ​​to flexibly set the final deflection effect of the detail normal map.

[0053] To obtain the texture coordinate rotation information of each pixel, the step "generating the texture coordinate rotation information of the pixel based on the provisional rotation value and preset rotation matrix" may include:

[0054] The preset rotation matrix is ​​adjusted based on the provisional selection value of the pixel to obtain the target rotation matrix, and the target rotation matrix is ​​used as the texture coordinate rotation information of the pixel.

[0055] For example, a computer device can calculate the texture coordinate rotation information corresponding to the texture coordinates of each pixel based on a provisional rotation value corresponding to each pixel. Specifically, a preset rotation matrix can be adjusted using each provisional rotation value to obtain a target rotation matrix. Subsequently, the target rotation matrix corresponding to each pixel can be used to process the texture coordinates corresponding to each pixel. Specifically, the preset rotation matrix can be as follows:

[0056]

[0057] Here, RotationMatrix is ​​the preset rotation matrix, and Angle is the provisional rotation value corresponding to each pixel. Substituting the provisional rotation value corresponding to each pixel into the preset rotation matrix will yield the target rotation matrix corresponding to each pixel.

[0058] 103. Based on the texture coordinate rotation information corresponding to each pixel, the texture coordinates of the pixel are transformed and calculated to obtain the rotated texture coordinates of each pixel.

[0059] Furthermore, the method for the step "transforming and calculating the texture coordinates of the pixel based on the texture coordinate rotation information corresponding to each pixel to obtain the rotated texture coordinates of each pixel" may include:

[0060] The texture coordinates of the pixel are transformed and calculated based on the target rotation matrix of the pixel to obtain the rotated texture coordinates of the pixel.

[0061] Specifically, the computer device can perform transformation calculations on the texture coordinates of each pixel based on the texture coordinate transformation formula, the target rotation matrix, and a preset two-dimensional vector to obtain the rotated texture coordinates of each pixel. The specific texture coordinate transformation formula is as follows:

[0062] UVRotation=transform(RotationMatrix,UV*FiberDensity)

[0063] Here, UVRotation represents the texture coordinates after rotation, RotationMatrix is ​​the target rotation matrix corresponding to each pixel, UV represents the texture coordinates of each pixel, and FiberDensity is a preset 2D vector. This 2D vector is a 2D vector that artists can flexibly set. Its two components are used to set the horizontal and vertical tiling density of the detail normal map after rotation, which can be used to adjust the length and density of the stitch texture.

[0064] For example, the texture coordinate rotation information corresponding to each pixel can be a two-dimensional spatial rotation matrix corresponding to each pixel. After obtaining the two-dimensional spatial rotation matrix corresponding to the pixel, the texture coordinates of the pixel can be transformed and calculated based on the two-dimensional spatial rotation matrix corresponding to the pixel and the two-dimensional vector preset by the artist, so as to obtain the texture coordinates of the pixel after rotation. The two-dimensional vector includes two components, which can be used to set the horizontal and vertical tiling density of the detail normal map after rotation, that is, it can be used to adjust the length and density of the stitch texture.

[0065] 104. Based on the rotated texture coordinates, sample the preset detail normal map to obtain sampled detail normal information.

[0066] 105. The sampled normal information is fused with the first normal information carried by the base normal map to obtain the second normal information.

[0067] 106. Based on the mask brightness value in the mask map and the second normal information, perform light and shadow rendering processing on the basic normal map to obtain the rendered detail texture, so as to display the rendered detail texture on the target virtual model.

[0068] To highlight the texture corresponding to the non-masked areas, before the step of "performing lighting and shadow rendering on the base normal map based on the mask brightness value in the mask map and the second normal information", the method may include:

[0069] The display information for each pixel is generated based on the mask brightness value of each pixel in the mask texture;

[0070] The basic normal map is subjected to lighting and shadow rendering based on the display information of each pixel and the second normal information to obtain the rendered detail texture.

[0071] Specifically, the method for the step "generating display information for each pixel based on the mask brightness value of each pixel in the mask texture" may include:

[0072] Determine the relationship between the mask brightness value of each pixel and the preset brightness reference value;

[0073] If the mask brightness value of the pixel is greater than the preset brightness reference value, then the pixel intensity of the pixel is set to the first preset value;

[0074] If the mask brightness value of the pixel is less than the preset brightness reference value, then the pixel intensity of the pixel is set to a second preset value, wherein the first preset value is greater than the second preset value.

[0075] For example, after obtaining the mask brightness value of each pixel in the mask map, the distribution intensity set for the detail normal map can be calculated first. This involves inputting the mask brightness value of each pixel into the distribution intensity function for processing, thus obtaining the display information of each pixel, i.e., the distribution intensity of each pixel. This distribution intensity function is shown below:

[0076] Mask=step(0.0001,MaskBrightness),

[0077] Here, Mask represents the distribution intensity, and MaskBrightness is the mask brightness value for each pixel. Specifically, this distribution intensity function sets the pixel intensity of pixels with a mask brightness value greater than 0.0001 to 1, and sets the pixel intensity of other pixels with a mask brightness value less than 0.0001 to 0.

[0078] Furthermore, the computer device can obtain the normal information that is ultimately distributed only within the non-masked area based on a preset function, which is shown below:

[0079] NormalFinal=lerp(Normal,NormalBlend,Mask)

[0080] Among them, NormalFinal is the second normal information for each pixel, Normal is the first normal information for each pixel, NormalBlend is the sampling detail normal information for each pixel, and Mask is the distribution intensity for each pixel.

[0081] To further illustrate the texture processing method for virtual models provided in this application embodiment, the following will take the application of the texture processing method for virtual models in a specific implementation scenario as an example. The specific application scenario is as follows.

[0082] (1) The computer device can acquire a mask map that is the same as the texture regions of multiple detail textures to be rendered in the base normal map. Each non-masked region in the mask map is set with a non-zero and different mask brightness value. Furthermore, the mask brightness of other non-masked regions of the mask map is set to 0 so that all other regions except the masked regions are displayed as black.

[0083] (2) After obtaining the mask brightness value of each pixel in the mask texture, the distribution intensity set for the detail normal map can be calculated first. That is, the mask brightness value of each pixel is input into the distribution intensity function for processing to obtain the display information of each pixel, that is, the distribution intensity of each pixel. The distribution intensity function is as follows:

[0084] Mask=step(0.0001,MaskBrightness),

[0085] Here, Mask represents the distribution intensity, and MaskBrightness is the mask brightness value for each pixel. Specifically, this distribution intensity function sets the pixel intensity of pixels with a mask brightness value greater than 0.0001 to 1, and sets the pixel intensity of other pixels with a mask brightness value less than 0.0001 to 0.

[0086] Furthermore, the computer device can convert each mask brightness value into a provisional rotation value according to the rotation value calculation formula, which is shown below:

[0087] Angle=MaskBrightness×AngleDiff+AngleBias

[0088] MaskBrightness is the brightness value of the mask for each pixel, AngleDiff is the preset angle difference value, and AngleBias is the preset angle offset value. Both the preset angle difference and preset angle offset values ​​are values ​​that artists can flexibly set according to actual design needs. The preset angle difference value is used to adjust the size of the angle difference between different gray levels, while the preset angle offset value is used to add an overall angle deflection to all rendered areas. Therefore, artists can use these two values ​​to flexibly set the final deflection effect of the detail normal map.

[0089] (3) The computer device can calculate the texture coordinate rotation information corresponding to the texture coordinates of each pixel based on the provisional rotation value corresponding to each pixel. Specifically, the preset rotation matrix can be adjusted using each provisional rotation value to obtain the target rotation matrix. Subsequently, the texture coordinates corresponding to each pixel can be processed using the target rotation matrix corresponding to each pixel. Specifically, the preset rotation matrix can be as follows:

[0090]

[0091] Here, RotationMatrix is ​​the preset rotation matrix, and Angle is the provisional rotation value corresponding to each pixel. Substituting the provisional rotation value corresponding to each pixel into the preset rotation matrix will yield the target rotation matrix corresponding to each pixel.

[0092] (4) The computer device can perform transformation calculations on the texture coordinates of each pixel based on the texture coordinate transformation formula, the target rotation matrix, and the preset two-dimensional vector to obtain the rotated texture coordinates of each pixel. Specifically, the texture coordinate transformation formula is as follows:

[0093] UVRotation=transform(RotationMatrix,UV*FiberDensity)

[0094] Here, UVRotation represents the texture coordinates after rotation, RotationMatrix is ​​the target rotation matrix corresponding to each pixel, UV represents the texture coordinates of each pixel, and FiberDensity is a preset 2D vector. This 2D vector is a 2D vector that artists can flexibly set. Its two components are used to set the horizontal and vertical tiling density of the detail normal map after rotation, which can be used to adjust the length and density of the stitch texture.

[0095] (5) Based on the rotated texture coordinates, sample the preset detail normal map to obtain sampled detail normal information. Then, fuse the sampled normal information with the first normal information carried by the base normal map to obtain the second normal information. Specifically, the computer device can obtain the normal information that is ultimately distributed only within the non-masked area according to a preset function, which is shown below:

[0096] NormalFinal=lerp(Normal,NormalBlend,Mask)

[0097] Among them, NormalFinal is the second normal information for each pixel, Normal is the first normal information for each pixel, NormalBlend is the sampling detail normal information for each pixel, and Mask is the distribution intensity for each pixel.

[0098] (6) After obtaining the second normal information for each pixel, the computer device performs lighting and shadow rendering processing on the basic normal map to obtain the rendered detail texture. For details, please refer to [link to documentation]. Figure 4 The above steps can be used to adjust an initial embroidery model, in which each embroidery area has the same stitch texture direction as the traditional process, into a target embroidery model where each embroidery area has a different stitch texture direction.

[0099] In summary, this application provides a texture processing method, apparatus, computer device, and storage medium for a virtual model. The method involves obtaining a mask map corresponding to the base normal map of a detail texture to be rendered. The base normal map includes multiple texture regions of the detail texture to be rendered. The non-masked regions of the mask map correspond one-to-one with the texture regions, and the mask brightness values ​​of the non-masked regions are not all equal. The detail texture to be rendered is a detail texture set for a target virtual model. Then, the mask brightness value of each pixel in the mask map is obtained, and each mask brightness value is converted into texture coordinate rotation information. The texture coordinates corresponding to different mask brightness values ​​change... The information is different; then, the texture coordinates of each pixel are transformed and calculated according to the texture coordinate rotation information corresponding to each pixel to obtain the rotated texture coordinates of each pixel; then, according to the rotated texture coordinates, the preset detail normal map is sampled to obtain sampled detail normal information; then, the sampled normal information is fused with the first normal information carried by the base normal map to obtain the second normal information; finally, the base normal map is subjected to lighting and shadow rendering processing based on the mask brightness value in the mask map and the second normal information to obtain the rendered detail texture, so as to display the rendered detail texture on the target virtual model. In this embodiment of the application, the pixel information of the base normal map can be adjusted according to the mask map and detail normal map including multiple non-masked areas with different mask brightness values, so that the texture display effect in different texture areas of the base normal map is different, which improves the realism of the rendered virtual embroidery model and enhances the user's visual experience.
