Description

Technical Field

[0001] This application relates to the field of computer technology, and more specifically, to a method, apparatus, storage medium, and electronic device for texture overlay processing. Background Technology

[0002] Currently, in the design and production of virtual models, normal maps are typically used to control the physically based rendering (PBR) materials of the models. However, many virtual models in a virtual scene need to be reused or modified (such as refurbishing old model resources and customizing models). After being exported to the engine, the reused or modified virtual models may exhibit poor texture display (such as being unclear or indistinct).

[0003] In related technologies, there are two main approaches to modifying and enhancing the texture of virtual models.

[0004] The first method involves importing the virtual model into a texture painting software (such as Substance Painter, SP); importing the normal map of the virtual model into SP, and applying the normal map to multiple faces of the virtual model; importing the normal texture map to be overlaid or enhanced into the corresponding layer of the normal map in SP; creating a new fill layer and adding the normal texture map to be overlaid to this fill layer for adjustment; and then exporting the new normal map. However, the drawback of this first method is that it requires repeating the import and export process multiple times for each virtual model to be modified, making the process cumbersome and inefficient; it also makes it impossible to overlay multiple texture maps simultaneously, and it is difficult to make local modifications or enhancements to the normal map.

[0005] The second method involves importing an existing normal map and the normal map to be overlaid (or enhanced) into graphics processing software (such as Photoshop, PS); blending them using layer blending tools (overlay mode or multiply mode); and controlling the texture intensity in the normal map by adjusting the opacity between layers to obtain a new normal map. However, the drawbacks of this second method are: the effect of using Photoshop's layer blending tools to overlay normal maps is poor, easily covering and destroying the original normal map; it cannot overlay multiple texture maps simultaneously, cannot perform local overlay and local enhancement of normal maps, and has poor control over the texture intensity of the normal map.

[0006] There is currently no effective solution to the above problems.

[0007] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0008] This application provides at least some embodiments a texture overlay processing method, apparatus, storage medium, and electronic device to at least solve the technical problems of the cumbersome operation, low efficiency, and difficulty in local overlay of normal map overlay methods provided in the related art.

[0009] According to one embodiment of this application, a texture overlay processing method is provided, comprising: obtaining a first texture, a second texture, and at least one third texture corresponding to a virtual 3D model, wherein the first texture is an initial normal map, the second texture is a material partition map, and the at least one third texture is a normal map to be overlaid; selecting at least one region to be overlaid from the second texture, wherein the at least one region to be overlaid corresponds to a local or all texture region in the first texture to be modified or enhanced; performing normal texture overlay on the at least one region to be overlaid using the at least one third texture to obtain at least one fourth texture; and rendering the virtual 3D model based on the first texture and the at least one fourth texture.

[0010] According to one embodiment of this application, a texture overlay processing apparatus is also provided, comprising: an acquisition module, configured to acquire a first texture, a second texture, and at least one third texture corresponding to a virtual 3D model, wherein the first texture is an initial normal texture, the second texture is a material partitioning texture, and the at least one third texture is a normal texture to be overlaid; a selection module, configured to select at least one region to be overlaid from the second texture, wherein the at least one region to be overlaid corresponds to a local or all texture region in the first texture to be modified or enhanced; an overlay module, configured to overlay the at least one region to be overlaid with normal textures using the at least one third texture to obtain at least one fourth texture; and a rendering module, configured to render the virtual 3D model based on the first texture and the at least one fourth texture.

[0011] According to one embodiment of this application, a computer-readable storage medium is also provided, wherein a computer program is stored in the computer-readable storage medium, and the computer program is configured to execute the texture overlay processing method described in any of the above claims when running.

[0012] According to one embodiment of this application, an electronic device is also provided, including: a memory and a processor, wherein the memory stores a computer program, and the processor is configured to run the computer program to perform the texture overlay processing method described in any of the above claims.

[0013] In at least some embodiments of this application, a first texture, a second texture, and at least one third texture corresponding to the virtual 3D model are first obtained. The first texture is an initial normal map, the second texture is a material partition map, and at least one third texture is a normal map to be overlaid. At least one region to be overlaid is selected from the second texture, where the at least one region to be overlaid corresponds to a local or all texture region in the first texture that needs to be modified or enhanced. At least one fourth texture is obtained by overlaying the at least one region to be overlaid with the at least one third texture. The virtual 3D model is then rendered based on the first texture and at least one fourth texture. This achieves the goal of overlaying the initial normal map with the normal map based on the material partition map to render the virtual 3D model. This simplifies the normal map overlay process, improves the efficiency of normal map overlay, and enhances the controllability of local texture overlay. It also solves the technical problems of the cumbersome operation, low efficiency, and difficulty in local overlay of the normal map overlay method provided by related technologies.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] It should be noted that, in the specification of this application, the word "for example" is used to mean "used as an example, illustration, or description." Any embodiment described as "for example" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use this application. In the following description, details are set forth for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid unnecessarily obscuring the description of this application. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0031] In the description of the embodiments of this application, some nouns or terms appearing shall be interpreted as follows:

[0032] Normal mapping: This refers to a texture that uses RGB color channels to mark the direction of the normal to each point on the surface of a virtual object. Normal mapping can display more detailed information about models with a higher polygon count.

[0033] Identifier maps (or ID maps): These are maps that use different colors to represent different virtual materials.

[0034] Currently, the PBR (Prep-Build) workflow is commonly used in the design and production of virtual models. However, a frequent issue arises during this process: the loss of high-poly models of the virtual or scene models leads to unclear textures when imported into the engine. In such cases, modifications to the normal map or texture overlays are necessary to optimize the model's texture display. When overlaying and enhancing the normal map of a virtual model, it may only be necessary to overlay multiple textures on multiple local areas of the normal map. In this case, the methods provided by relevant technologies require sequentially overlaying and controlling multiple textures on multiple local areas of the normal map, which is cumbersome and inefficient.

[0035] In one possible implementation of this application, the method of manually overlaying multiple textures sequentially based on SP or PS, which is commonly used in computer technology scenarios involving the overlay of normal maps of virtual models, still suffers from technical problems such as cumbersome overlay operations, low efficiency, and poor controllability of local texture overlay after practice and careful research. Therefore, the scenario applied to the embodiments of this application can be any scenario in the computer field involving the enhancement or modification of virtual model normal maps, and the target game type can be action, adventure, simulation, role-playing, and casual games, etc.

[0036] This application proposes a texture overlay processing method. It employs a procedural normal map blending tool in conjunction with the ID map of a virtual model to quickly overlay or modify the normal map to be modified in Photoshop. This simplifies the normal map overlay process, improves the efficiency of normal map overlay, and enhances the controllability of local texture overlay. It also solves the technical problems of cumbersome operation, low efficiency, and difficulty in local overlay of the normal map overlay methods provided by related technologies.

[0037] The methods described in this application can be executed in a terminal device (e.g., a mobile terminal, a computer terminal, or a similar computing device). Taking a mobile terminal as an example, the mobile terminal can be a smartphone, tablet computer, PDA, mobile internet device, PAD, game console, or other terminal device.

[0038] Figure 1 This is a hardware structure block diagram of a mobile terminal according to a texture overlay processing method based on one embodiment of this application. For example... Figure 1 As shown, a mobile terminal may include one or more ( Figure 1 (Only one is shown) Processor 102, memory 104, transmission device 106, input / output device 108, and display device 110. Taking the application of texture overlay processing method to a video game scene through this mobile terminal as an example, processor 102 calls and runs the computer program stored in memory 104 to execute the texture overlay processing method. The virtual 3D model in the rendered video game scene is transmitted to input / output device 108 and / or display device 110 through transmission device 106, thereby providing the virtual 3D model to the player.

[0039] Still as Figure 1 As shown, the processor 102 may include, but is not limited to, processing devices such as: Central Processing Unit (CPU), Graphics Processing Unit (GPU), Digital Signal Processing (DSP) chip, Microcontroller Unit (MCU), Field Programmable Gate Array (FPGA), Neural-Network Processing Unit (NPU), Tensor Processing Unit (TPU), Artificial Intelligence (AI) type processor, etc.

[0040] Those skilled in the art will understand that Figure 1 The structure shown is for illustrative purposes only and does not limit the structure of the mobile terminal described above. For example, the mobile terminal may also include components that are more... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0041] In some optional embodiments primarily focused on gaming scenarios, the aforementioned terminal device may also provide a human-computer interaction interface with a touch-sensitive surface. This interface can sense finger contact and / or gestures to interact with a graphical user interface (GUI). The human-computer interaction functions may include the following: creating web pages, drawing, word processing, creating electronic documents, playing games, video conferencing, instant messaging, sending and receiving emails, call interfaces, playing digital videos, playing digital music, and / or web browsing, etc. Executable instructions for performing the aforementioned human-computer interaction functions are configured / stored in one or more processor-executable computer program products or readable storage media.

[0042] The methods described in this application can also be executed on a server. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing 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. Taking the texture overlay processing method applied to a video game scene via a video game server as an example, the video game server can render a virtual 3D model in the video game scene based on this texture overlay processing method and provide this virtual 3D model to the player (e.g., it can be rendered and displayed on the player's terminal screen, or provided to the player through holographic projection, etc.).

[0043] According to one embodiment of this application, an embodiment of a texture overlay processing method is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0044] In one possible implementation, this application provides a texture overlay processing method running on the aforementioned mobile terminal. Figure 2 This is a flowchart of a texture overlay processing method according to one embodiment of this application, such as... Figure 2 As shown, the method includes the following steps:

[0045] Step S21: Obtain the first texture, the second texture, and at least one third texture corresponding to the virtual 3D model, wherein the first texture is the initial normal map, the second texture is the material partition map, and at least one third texture is the normal map to be overlaid.

[0046] The aforementioned virtual 3D models can be virtual character models, virtual item models, and virtual prop models in game scenes, etc.

[0047] The aforementioned game scene can be a virtual game scene involving the enhancement or modification of virtual model normal maps. The corresponding game type can be: action (e.g., first-person or third-person shooter games, 2D or 3D fighting games, war action games, and sports action games), adventure (e.g., exploration games, collection games, puzzle games), simulation (e.g., sandbox simulation games, simulation games, strategy simulation games, city-building simulation games, business simulation games), role-playing games, and casual (e.g., board games, casual competitive games, music rhythm games, dress-up games, etc.).

[0048] The first texture mentioned above can be the initial normal map of the virtual 3D model. This initial normal map is used to determine the original normal texture of the virtual 3D model.

[0049] The second texture map mentioned above can be a material partition map (equivalent to an ID map) of the aforementioned virtual 3D model. This material partition map can be used to identify different virtual materials of the aforementioned virtual 3D model by using different colors.

[0050] The third texture mentioned above can be the normal map to be overlaid on the virtual 3D model. For example, when modifying the initial normal map of the virtual 3D model, the third texture can be a normal map pre-specified by the technician to determine the modified normal texture.

[0051] The aforementioned at least one third texture can be multiple third textures. These multiple third textures can be normal textures to be superimposed corresponding to multiple local regions of the initial normal texture of the aforementioned virtual 3D model.

[0052] The specific implementation methods for obtaining the first texture, second texture, and at least one third texture corresponding to the virtual 3D model can be, but are not limited to, pre-drawn by art designers using graphics drawing software, or selected from a preset texture database.

[0053] Step S22: Select at least one region to be superimposed from the second texture map, wherein the at least one region to be superimposed corresponds to a local or all texture region in the first texture map that needs to be modified or enhanced.

[0054] It is easy to understand that at least one region to be superimposed from the second texture image can correspond to a texture region to be modified or enhanced in the first texture image (e.g., a region with insufficient texture clarity, a region with missing texture, or a region with texture modification requirements).

[0055] The area to be modified or enhanced in the first texture image can be the entire texture area of ​​the first texture image. In this case, all material partitions are selected from the second texture image as the area to be overlaid.

[0056] The area to be modified or enhanced in the first texture image can also be one or more local texture areas of the first texture image. In this case, one or more areas to be superimposed are selected from the second texture image, each corresponding to one or more local texture areas.

[0057] Specifically, the above-mentioned selection of at least one region to be overlaid from the second image may also include other methods and steps, which can be referred to in the further description of the embodiments of this application below, and will not be repeated here.

[0058] Step S23: Use at least one third texture to overlay normal textures onto at least one region to be overlaid, to obtain at least one fourth texture;

[0059] Using at least one of the above-mentioned normal maps to be superimposed (equivalent to the third map), normal textures can be superimposed on the at least one region to be superimposed, thereby obtaining the fourth map. The fourth map can be used to determine the superimposed normal texture within the at least one region to be superimposed.

[0060] It should be noted that the above-described process of using at least one third texture to overlay normal textures onto at least one region can be accomplished using graphics editing software (such as Photoshop).

[0061] Specifically, the above-mentioned method of using at least one third texture to overlay normal textures on at least one region to obtain at least one fourth texture may also include other methods and steps, which can be referred to in the further description of the embodiments of this application below, and will not be repeated here.

[0062] Step S24: Render the virtual 3D model based on the first texture and at least one fourth texture.

[0063] Based on the initial normal map (equivalent to the first map) and at least one fourth map obtained by overlaying normal textures on at least one region to be overlaid, the virtual 3D model in the game scene can be rendered. The model texture of the rendered virtual 3D model includes the modified normal texture corresponding to the at least one third map.

[0064] Specifically, the above-mentioned rendering of the virtual 3D model based on the first texture and at least one fourth texture may also include other methods and steps, which can be referred to in the further description of the embodiments of this application below, and will not be repeated here.

[0065] It is readily understood that, through the above embodiments of this application, for the needs of repeated modification, local modification, and local overlay of virtual model normal maps, the normal map overlay method, in conjunction with the ID map of the virtual model, allows for rapid local overlay or modification of the normal map to be modified within the graphic design software, avoiding multiple import and export processes of the model and textures. The above method can also simultaneously overlay multiple normal maps with a single click (both local and global overlays), and the texture intensity can be easily controlled for each local area of ​​the normal map to be overlaid. The overlay effect is good, the speed is fast, the controllability is strong, and the operation is simple and intuitive.

[0066] In at least some embodiments of this application, a first texture, a second texture, and at least one third texture corresponding to the virtual 3D model are first obtained. The first texture is an initial normal map, the second texture is a material partition map, and at least one third texture is a normal map to be overlaid. At least one region to be overlaid is selected from the second texture, where the at least one region to be overlaid corresponds to a local or all texture region in the first texture that needs to be modified or enhanced. At least one fourth texture is obtained by overlaying the at least one region to be overlaid with the at least one third texture. The virtual 3D model is then rendered based on the first texture and at least one fourth texture. This achieves the goal of overlaying the initial normal map with the normal map based on the material partition map to render the virtual 3D model. This simplifies the normal map overlay process, improves the efficiency of normal map overlay, and enhances the controllability of local texture overlay. It also solves the technical problems of the cumbersome operation, low efficiency, and difficulty in local overlay of the normal map overlay method provided by related technologies.

[0067] The methods described in the embodiments of this application will be further described below.

[0068] Optionally, in step S22, selecting at least one region to be overlaid from the second texture image may include the following steps:

[0069] Step S221: Obtain multiple different color regions of the second texture. These multiple different color regions are used to represent the different materials corresponding to the different components of the virtual 3D model.

[0070] Step S222: Select at least one color region from multiple different color regions;

[0071] Step S223: Determine at least one region to be overlaid based on at least one color region.

[0072] The material partition map (equivalent to a second map) of the aforementioned virtual 3D model can include multiple different color regions, which represent the different materials corresponding to the different components of the virtual 3D model. Therefore, after the structural design of the virtual 3D model is completed, technicians can control the rendering material of the virtual 3D model by adjusting the material map of a specified color region in the aforementioned material partition map, facilitating its application in real-world scenarios.

[0073] The specific implementation process of selecting at least one region to be superimposed from the second texture image can be as follows: select at least one color region from multiple different color regions of the second texture image, and determine the at least one region to be superimposed based on the at least one color region.

[0074] Figure 3 This is a schematic diagram of a virtual three-dimensional model according to one embodiment of this application. Figure 4 This is a schematic diagram of the surface structure of a virtual three-dimensional model according to one embodiment of this application, such as... Figure 3 and Figure 4 As shown, the virtual 3D model is a virtual cube model in the game scene. The virtual 3D model includes 6 faces: face 301, face 302, face 303, face 304, face 305 and face 306.

[0075] Figure 5 This is a schematic diagram of an initial normal map according to one embodiment of this application, such as... Figure 4 and Figure 5 As shown, in the above virtual cube model to be modified, the normal textures of every two faces are the same: the normal textures of face 301 and face 304 are the same, the normal textures of face 302 and face 305 are the same, and the normal textures of face 303 and face 306 are the same.

[0076] Figure 6 This is a schematic diagram of a material partitioning texture according to one embodiment of this application, such as... Figure 6 As shown, the material partitioning map can include 6 color regions, which correspond to the 6 faces of the virtual cube model mentioned above: color region 601 corresponds to face 301, color region 602 corresponds to face 302, color region 603 corresponds to face 303, color region 604 corresponds to face 304, color region 605 corresponds to face 305, and color region 606 corresponds to face 306.

[0077] Still as Figure 6As shown, the six color regions in the material partition map can correspond to different colors, with the same color indicating the same virtual material. Color regions 601 and 604 both correspond to color 1 (e.g., red), and correspondingly, faces 301 and 304 of the virtual cube model have the same virtual material. Color regions 602 and 605 both correspond to color 2 (e.g., green), and correspondingly, faces 302 and 305 of the virtual cube model have the same virtual material. Color regions 603 and 606 both correspond to color 3 (e.g., blue), and correspondingly, faces 303 and 306 of the virtual cube model have the same virtual material.

[0078] Still as Figure 6 As shown, when modifying the normal map of the virtual cube model, technicians can select color region 602 and color region 606 from the six color regions of the material partition map as target color regions (equivalent to at least one of the aforementioned color regions) according to scene requirements; further, the texture regions corresponding to the face 302 of color region 602 and the face 306 of color region 606 (in such a way as...) Figure 5 The region corresponding to the initial normal map shown is determined as the region to be overlaid.

[0079] Optionally, in step S23, performing normal texture overlay on at least one region to be overlaid using at least one third texture to obtain at least one fourth texture may include the following steps:

[0080] Step S231: From at least one third texture, select at least one third texture corresponding to each region to be overlaid in the region to be overlaid, and obtain the selection result;

[0081] Step S232: Perform normal texture overlay on at least one region to be overlaid according to the selection result to obtain at least one fourth texture.

[0082] The aforementioned at least one third texture can be at least one normal texture corresponding to the aforementioned virtual 3D model to be overlaid. From this at least one third texture, a corresponding third texture can be selected for each of the at least one overlay region. In particular, depending on the requirements of the application scenario, each of the at least one overlay region can select its own different third texture, and any two of the at least one overlay region can also select the same third texture.

[0083] The selection result described above can be the correspondence between each region to be overlaid and the selected third texture. Based on this selection result, normal texture overlay can be performed on at least one region to be overlaid to obtain at least one fourth texture.

[0084] Figure 7This is a schematic diagram of a normal map to be overlaid according to one embodiment of this application. Figure 8 This is a schematic diagram of another normal map to be superimposed according to one embodiment of this application, such as... Figure 7 and Figure 8 As shown, texture 701 and texture 801 are normal maps that are pre-made or pre-obtained by technicians for modifying the normal map of the aforementioned virtual cube model.

[0085] like Figure 6 , Figure 7 and Figure 8 As shown, when modifying the normal map of the virtual cube model, texture 701 can be selected as the texture to be superimposed for the area to be superimposed corresponding to color region 606, and texture 801 can be selected as the texture to be superimposed for the area to be superimposed corresponding to color region 602.

[0086] Optionally, in step S232, performing normal texture overlay on at least one region to be overlaid according to the selection result to obtain at least one fourth texture may include the following execution steps:

[0087] Step S2321: Add a mask to the third texture corresponding to each region to be overlaid according to the selection result, wherein the outline of the mask is determined by the outline of the corresponding region to be overlaid.

[0088] Step S2322: Determine the texture corresponding to the mask from the third texture corresponding to each region to be overlaid;

[0089] Step S2323: Overlay the texture corresponding to the mask with at least one region to be overlaid using normal texture to obtain at least one fourth texture.

[0090] The outline of the mask can be determined based on the outline of the areas to be overlaid. Following the selection of the third texture for each area to be overlaid, a mask is added to the third texture corresponding to each area. This mask is used to determine the area in the third texture used for texture overlay.

[0091] The texture corresponding to the mask is determined from the third texture corresponding to each of the above-mentioned areas to be superimposed. The texture corresponding to the mask can be a partial texture of the third texture.

[0092] By overlaying the texture corresponding to the mask with the at least one area to be overlaid using normal textures, at least one fourth texture can be obtained. The number of fourth textures corresponds to the number of times the normal texture is overlaid.

[0093] Still as Figure 6 and Figure 7 As shown, since texture 701 is selected as the texture to be overlaid for the area to be overlaid corresponding to color region 606, the outline of color region 606 is determined as follows: Figure 7 The outline 702 is shown, and a mask is added to the texture 701 according to the outline 702, thereby obtaining a local texture within the outline 702 in the texture 701 (denoted as the local texture). Figure 7 (This is equivalent to the fourth texture mentioned above).

[0094] Still as Figure 6 and Figure 8 As shown, since texture 801 is selected as the texture to be overlaid for the area to be overlaid corresponding to color region 602, the outline of color region 602 is determined as follows: Figure 8 The outline 802 is shown, and a mask is added to the texture 801 according to the outline 802, thereby obtaining a local texture within the outline 802 in the texture 801 (denoted as the local texture). Figure 8 (This is equivalent to the fourth texture mentioned above).

[0095] Optionally, in step S24, rendering the virtual 3D model based on the first texture and at least one fourth texture may include the following steps:

[0096] Step S241: Perform normal texture overlay on the first texture and at least one fourth texture to obtain the fifth texture;

[0097] Step S242: Render the virtual 3D model using the fifth texture.

[0098] By overlaying the initial normal map of the virtual 3D model and at least one of the fourth maps with normal textures, the fifth map can be obtained. This fifth map can be used to re-render the virtual 3D model to obtain the normal effect of the overlaid model.

[0099] It should be noted that in the above method steps of the embodiments of this application, the process of overlaying normal textures can be implemented by graphics design software (such as PS), and the process of rendering virtual 3D models can be implemented by a preset game engine (such as UE4, UE5, etc.).

[0100] Optionally, in step S241, performing normal texture overlay on the first texture and at least one fourth texture to obtain a fifth texture may include the following steps:

[0101] Step S2411: In response to a touch operation performed on multiple adjustment controls, adjust the normal intensity of the first texture and at least one fourth texture to preview the current overlay result in real time. The multiple adjustment controls are used to control the normal intensity of each texture in the first texture and at least one fourth texture respectively.

[0102] Step S2412: In response to the touch operation performed on the confirmation control, the current overlay result is determined as the fifth texture.

[0103] The aforementioned multiple adjustment controls can be multiple adjustment controls corresponding to the normal texture overlay process. These multiple adjustment controls are used to control the normal intensity of the texture during the normal texture overlay process. Specifically, each of these multiple adjustment controls is used to control the normal intensity of each texture in the first texture and the at least one fourth texture, respectively. For example, when there are three fourth textures, the number of the multiple adjustment controls can be four, where one adjustment control is used to control the normal intensity of the first texture, and the other three adjustment controls are used to control the normal intensity of the three fourth textures, respectively.

[0104] When adjusting the normal intensity of the first texture and at least one fourth texture using the aforementioned adjustment controls, the current normal texture overlay result can be previewed in real time based on the currently adjusted normal intensity value. The aforementioned confirmation control is used to confirm the currently adjusted normal intensity value. When a touch operation is detected on the confirmation space, the current overlay result is determined as the fifth texture. This fifth texture can be used to re-render the virtual 3D model to obtain the overlaid model normal effect.

[0105] It should be noted that the touch operations performed on the multiple adjustment and confirmation controls described above can all be performed by the user touching the display screen of the terminal device with their finger and controlling the operation of the terminal device. Touch operations can include single-point touch and multi-point touch, where the touch operation of each touch point can include clicking, long pressing, hard pressing, swiping, etc. The above touch operations can also be implemented through input devices such as a mouse and keyboard.

[0106] Figure 9 This is a schematic diagram of a modified normal map according to one embodiment of this application, such as... Figure 9 As shown, for the three normal maps (including...) Figure 5 The initial normal map of the virtual cube model shown, and the aforementioned local texture Figure 7 And the above partial stickers Figure 8 When performing normal texture overlay, the normal intensity of the three normal maps can be controlled through the control bar corresponding to the overlay process (for example, the operation bar in graphic design software).

[0107] Still as Figure 9 As shown, by dragging the control handle corresponding to intensity 1 (equivalent to one of the aforementioned adjustment controls) via touch gestures, the normal intensity of the initial normal map can be controlled to be 100%; by dragging the control handle corresponding to intensity 2 (equivalent to one of the aforementioned adjustment controls) via touch gestures, the normal intensity of the local normal map can be controlled to be 100%. Figure 7 The normal intensity is 100%; by dragging the control handle corresponding to intensity 3 (equivalent to one of the aforementioned adjustment controls) via touch gestures, the above-mentioned local patch can be controlled. Figure 8The normal intensity is 100%.

[0108] Still as Figure 9 As shown, the display area of ​​normal map 901 can preview the normal texture overlay result in real time according to the intensity value currently adjusted by the three control handles in the control bar. When the user clicks the confirmation button in the control bar (equivalent to the confirmation control mentioned above), the currently previewed normal map is exported to obtain normal map 901 (equivalent to the fifth map mentioned above) for re-rendering the virtual cube model.

[0109] Still as Figure 6 and Figure 9 As shown, compared to the initial normal map, the above-mentioned initial normal map and the above-mentioned local map... Figure 7 And the above partial stickers Figure 8 In the normal map 901 obtained after normal texture overlay, the normal texture in the area to be overlaid corresponding to color region 602 is modified to a local texture. Figure 8 The normal texture of the area to be overlaid, corresponding to color region 606, was modified to a local texture. Figure 7 The normal texture allows for local modification of the normal map.

[0110] Figure 10 This is a schematic diagram of a modified virtual 3D model according to one embodiment of this application. Figure 11 This is a schematic diagram of the surface structure of a modified virtual 3D model according to one embodiment of this application, such as... Figure 10 and Figure 11 As shown, by rendering the virtual cube model using the aforementioned normal map 901, a modified virtual cube model can be obtained. Compared to the original virtual cube model, the normal textures of face 1102 (corresponding to face 302 before modification) and face 1106 (corresponding to face 306 before modification) in the modified virtual cube model are modified to their respective specified textures.

[0111] Optionally, in the above texture overlay processing method: the fifth texture and the first texture are stored in different storage locations to output the first rendering result or the second rendering result separately, or the comparison result between the first rendering result and the second rendering result is output synchronously, wherein the first rendering result is the rendering result of the virtual 3D model by the first texture, and the second rendering result is the rendering result of the virtual 3D model by the fifth texture.

[0112] Taking the modification and re-rendering of the normal map of the virtual cube model as an example, the normal map 901 generated by the above normal texture overlay (equivalent to the fifth map above) and the above initial normal map (equivalent to the first map above) can be stored separately. That is to say, when modifying the normal map corresponding to the model, the initial normal map will not be modified, but a new normal map will be regenerated.

[0113] Based on the above normal map 901 and the initial normal map, the virtual cube model before modification can be output separately using the initial normal map (e.g., Figure 3 The virtual cube model shown is equivalent to the first rendering result mentioned above. Alternatively, the modified virtual cube model can be output separately using normal map 901 (e.g., Figure 10 The virtual cube model shown is equivalent to the second rendering result mentioned above. It can also use normal map 901 and the initial normal map to output the virtual cube model before and after modification to display the comparison results.

[0114] In summary, in the embodiments of this application, for the needs of repeated modification, local modification, and local overlay of virtual model normal maps, the normal map overlay method can be used in conjunction with the ID map of the virtual model to quickly overlay or modify the normal map to be modified in the graphic design software, avoiding multiple import and export processes of the model and the map.

[0115] The method described in this application embodiment can also simultaneously overlay multiple normal maps with one click (it can be local overlay or global overlay), and perform individual normal intensity control on each local area of ​​the normal map to be overlaid. The overlay effect is good, the speed is fast, the controllability is strong, and the operation is simple and intuitive.
