Description

Technical Field

[0001] This application relates to the field of computer graphics technology, specifically to a model coloring method, apparatus, storage medium, device, and program product. Background Technology

[0002] In game development and virtual character representation, the same virtual object (such as a game character) is often represented using both 3D models and 2D skeletal animation models to meet the rendering requirements of different scenarios. For example, high-precision 3D models are used in combat scenes to obtain better lighting and spatial sense, while 2D skeletal animation is used in UI avatars, skill effects, or certain 2D rendering scenarios to save performance and maintain a consistent art style.

[0003] To enable features such as character customization, equipment coloring, rarity-based color changes, and faction identification, real-time coloring of different parts of the virtual character is required. However, because the material parameters of the 3D model and the 2D skeletal animation model are managed independently, when the coloring parameters of one (such as the 3D model) change, the other (such as the 2D skeletal animation model) cannot automatically synchronize. This results in inconsistent colors for the same character in different dimensions, affecting visual uniformity.

[0004] There is a lack of technical solutions in the relevant fields that can automatically, quickly, and accurately synchronize the real-time coloring parameters of a 3D model to a 2D skeletal animation model and complete the real-time coloring process. Summary of the Invention

[0018] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] This application provides a model coloring method, apparatus, storage medium, device, and program product. Specifically, the model coloring method of 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, smart TV, wearable smart device, smart vehicle terminal, etc. The terminal can also include a client, which can be a game client, browser client, instant messaging client, or mini-program, etc. 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, content delivery networks (CDN), and big data and artificial intelligence platforms.

[0020] In this embodiment, the execution entity of the model coloring method can be a terminal device or a server. The terminal device can be a local terminal device or a client device in the aforementioned cloud gaming. This embodiment does not limit the type of execution entity.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a model coloring system provided in an embodiment of this application. The system can implement the model coloring method provided in this embodiment. The system may include a terminal 1000, a server 2000, and a network 3000. The terminal 1000 and the server 2000 can interact with each other via the network 3000, which may be a wide area network (WAN), a local area network (LAN), or a combination of both.

[0022] Terminal 1000 can be an electronic device with graphics rendering capabilities, such as a smartphone, tablet, personal computer, or game console, running a game client or a virtual character display application. Terminal 1000 loads at least two different dimensional models of the same virtual object, including a first model (preferably a 3D model) and a second model (e.g., a Spine 2D skeletal animation model). The first model corresponds to a first model material, and the second model corresponds to a second model material, with a pre-established color parameter binding relationship between the first model material and the second model material.

[0023] Server 2000 can be used as a cloud gaming server, a game backend server, or a dedicated rendering computing server.

[0024] In some embodiments, when a player triggers a character coloring operation (such as equipment coloring, faction color changing, rarity color changing, etc.) in the terminal 1000, causing the coloring parameters of the first model material to change, the server 2000 obtains the updated real-time coloring parameters of the first model material.

[0025] Server 2000 synchronizes the real-time shading parameters to the second model material based on the pre-stored or real-time queried binding relationship between the first and second model materials. Subsequently, server 2000 performs real-time shading processing on the second model based on the synchronized real-time shading parameters. Specifically, when rendering the second model, server 2000's graphics rendering pipeline passes the synchronized real-time shading parameters to the corresponding material shader of the second model. The shader then performs real-time shading rendering of the second model, generating a shading-processed rendering result, which is pushed to terminal 1000 for display in real-time via network 3000, thus ensuring that the shading effect of the same virtual object is completely consistent in both the 3D model and the 2D skeletal animation model.

[0026] Through the above system implementation, when any change occurs in the coloring parameters of the first model, the system can automatically and in real time synchronize the change to the second model, and complete the real-time coloring processing of the second model on the terminal or server, so as to achieve complete unification and instant update of the coloring parameters of the same virtual object in different dimensional models.

[0027] Please see Figure 2 , Figure 2 This is a flowchart illustrating the model coloring method provided in an embodiment of this application. It should be noted that the steps shown may be executed in a different logical order than that shown in the flowchart. The method may include the following steps: Step 110: In response to the change in the shading parameters of the first model material, obtain the updated real-time shading parameters of the first model material, wherein the first model material corresponds to the first model.

[0028] In the embodiments of this application, the first model and the second model are two different dimensions of the same virtual object, used to represent different dimensional representations of the same virtual object (e.g., a game character). The first model material and the second model material are attribute layers that control the visual representation of the first model and the second model, respectively.

[0029] In one specific embodiment provided in this application, the first model and the second model are, for example, a three-dimensional model and a two-dimensional skeletal animation model.

[0030] During gameplay, users or the game system may perform coloring operations on virtual objects, such as changing the color of clothing, hair, or skin. When the coloring parameters of the first model's material change, it is necessary to obtain the updated real-time coloring parameters in a timely manner so that they can be synchronized to the second model.

[0031] In some embodiments, in response to a change in the shading parameters of the first model material, the updated real-time shading parameters of the first model material are obtained, including: The parameter synchronization manager monitors the changes in the coloring state of the first model's material in real time. In response to the parameter synchronization manager detecting a change in the coloring state of the first model material, the real-time coloring parameters of the first model material are read through the parameter synchronization manager.

[0032] In some embodiments, the parameter synchronization manager is a dedicated functional module for managing and synchronizing shading parameters. The parameter synchronization manager monitors the shading status of the first model material in real time through an event listening mechanism or a polling mechanism. When a change in the shading parameters (such as hue, saturation, and brightness) of the first model material is detected, the parameter synchronization manager immediately triggers a parameter reading operation to obtain the latest shading parameter values ​​from the first model material. This real-time monitoring mechanism ensures that changes in shading parameters are captured promptly, providing a data foundation for subsequent parameter synchronization.

[0033] In some embodiments, the real-time color parameters are based on the HSV color model and include at least one of hue, saturation, and lightness.

[0034] The HSV color model is a color representation method based on human visual perception. Compared to the traditional RGB color model, the HSV color model better aligns with human intuitive color perception, facilitating color adjustment and dyeing operations. Hue represents the basic attributes of color, such as red, green, and blue; saturation represents the purity or vividness of a color; and lightness represents the brightness or darkness of a color. By adjusting HSV parameters, a wide variety of dyeing effects can be achieved. For example, changing only the hue can turn red clothing blue, while keeping saturation and lightness constant ensures consistent color gradation before and after dyeing.

[0035] Step 120: Based on the coloring parameter binding relationship between the first model material and the second model material, synchronize the real-time coloring parameters to the second model material. The second model material corresponds to the second model, and the first model and the second model are two different dimensions of the same virtual object.

[0036] In this embodiment, a pre-established coloring parameter binding relationship is established between the first model material and the second model material. This coloring parameter binding relationship defines the correspondence between the coloring areas of the first model and the coloring areas of the second model, as well as the mapping rules for the coloring parameters used in each coloring area. For example, the coloring area of ​​the "top" of the first model (3D model) is bound to the coloring area of ​​the "top" of the second model (Spine 2D model). When the color parameters of the top of the 3D model change, the parameters will automatically be synchronized to the top area of ​​the Spine model.

[0037] Specifically, in step 120, after obtaining the real-time coloring parameters of the first model material, the parameter synchronization manager searches for the corresponding second model material according to the preset coloring parameter binding relationship, and then writes the real-time coloring parameters into the corresponding attribute of the second model material. This synchronization process is completed in milliseconds, ensuring that the coloring effects of the first and second models are consistent.

[0038] It should be noted that in games or applications, the same virtual object may be presented in 2D and 3D forms in different scenes or perspectives. For example, a 3D model may be used when displaying the main interface of a game, while Spine 2D animation may be used in a battle scene. Through the parameter synchronization mechanism of this application, regardless of which display mode the user performs coloring operations on the character, the character coloring effect in the other display mode can be kept synchronized in real time, providing the user with a consistent visual experience.

[0039] Step 130: Based on the synchronized real-time staining parameters, perform real-time staining processing on the second model.

[0040] After obtaining the synchronized real-time coloring parameters, the second model needs to be colored in real-time to ensure that the visual effect of the second model is consistent with that of the first model.

[0041] In some embodiments, the second model is subjected to real-time staining processing based on synchronized real-time staining parameters, including: Based on the synchronized real-time coloring parameters, the second model is colored in real-time using a graphics processor.

[0042] In this embodiment, a graphics processing unit (GPU) is introduced to perform real-time coloring processing on the second model. GPUs possess powerful parallel computing capabilities, enabling them to handle coloring calculations for a large number of pixels simultaneously. Compared to using a CPU for coloring calculations, the GPU's parallel processing significantly improves coloring efficiency.

[0043] When performing real-time coloring on the second model, the process is executed in parallel by the GPU during each frame rendering, thereby achieving efficient real-time coloring effects.

[0044] In some embodiments, the second model is subjected to real-time staining processing based on the synchronized real-time staining parameters, including steps 1301 to 1302: Step 1301: Obtain the pre-generated multi-channel staining mask of the second model, wherein different channels of the multi-channel staining mask are used to define different staining regions in the second model.

[0045] In this embodiment, a multi-channel shading mask is a texture image used to precisely control shading regions. The multi-channel shading mask utilizes different color channels of the image (such as R, G, B, and A channels) to store masking information for different shading regions. The pixel value of each channel (typically ranging from 0-1 or 0-255) represents the shading weight or intensity of the shading region corresponding to that pixel location. A higher pixel value indicates a greater influence of the corresponding shading parameters on the pixel; a pixel value of 0 indicates that the pixel does not participate in the shading of that region.

[0046] For example, for a game character, the R channel can be used to store the mask for the "hair" area, the G channel for the "shirt" area, the B channel for the "pants" area, and the A channel for the "shoes" area. In this way, a single multi-channel mask texture can control four independent shading areas simultaneously, saving texture resources while providing pixel-level precise shading control.

[0047] In some embodiments, the method for generating a multi-channel staining mask includes the following steps 01 to 03: Step 01: Obtain the original texture of the second model.

[0048] The original texture of the second model is the base texture image used by the second model, which contains the basic appearance information of the virtual object.

[0049] Step 02: Based on the color of the first model, perform color alignment processing on the original texture to obtain the color-aligned texture of the second model.

[0050] Specifically, the purpose of color alignment is to ensure that the base color of the second model is consistent with the base color of the first model. Since 2D and 3D textures may be created by different artists or use different color configurations, color alignment is necessary before color synchronization to ensure consistency in the subsequent coloring effect. Color alignment can be achieved by adjusting parameters such as hue, saturation, and brightness of the original texture to match the colors of corresponding areas on the first model.

[0051] Please see Figure 3 , Figure 3This is a schematic diagram of the texture after color alignment processing for the model, as described in this embodiment. In actual processing, due to differences in the original art production environment between the 2D Spine model and the 3D model (e.g., different color temperatures and brightness), direct coloring will lead to color differences. Therefore, this embodiment first uses the base color of the 3D model as a reference to uniformly correct the hue, saturation, and brightness of the original texture of the Spine model, generating a texture as shown below. Figure 3 The color-aligned texture shown is used to preserve the character's visual details (such as dragon scales and wing textures) and ensure that the base color remains consistent with the 3D model when subsequent coloring parameters are overlaid.

[0052] Step 03: Mark and extract different stained areas on the color alignment map to obtain a multi-channel stained mask.

[0053] Specifically, in step 03, on the color alignment map, the stained areas of the virtual object that need to be stained (such as hair, clothes, etc.) are selected, and the selection information of each stained area is stored in different channels of the mask texture.

[0054] Please see Figure 4 , Figure 4 This is a schematic diagram illustrating the extraction process of the multi-channel staining mask provided in an embodiment of this application. Figure 4 The left side shows a breakdown of the Spine model's components (such as the dragon's horns, body slices, etc.), and the right side shows the corresponding generated single-channel mask image (e.g., R-channel mask). During the production process, technicians or automated scripts will select... Figure 4 The areas on the left that require specific coloring (e.g., body parts that need to be dyed red) are marked as white (pixel value 1 or 255) in the mask texture, while areas that do not need coloring are marked as black (pixel value 0). For example... Figure 4 As shown on the right, the white area precisely defines the scope of the coloring parameters. Different coloring areas (such as the body, wings, and horns) can correspond to different channels of the mask texture (R, G, B, A), thus enabling a single texture to control the precise coloring of four independent areas, effectively preventing color overflow onto the background or other areas that do not need to be changed. Through the mask generation process described above, a precise multi-channel staining mask can be pre-made for the second model, providing a basis for regional control in subsequent real-time staining processing.

[0055] Step 1302: Based on the multi-channel staining mask and the synchronized real-time staining parameters, perform real-time staining processing on the second model.

[0056] After obtaining the multi-channel staining mask and synchronized real-time staining parameters corresponding to the second model, the second model can be subjected to real-time staining processing.

[0057] In some embodiments, the second model is subjected to real-time staining processing based on a multi-channel staining mask and synchronized real-time staining parameters, including the following steps 001 to 003: Step 001: For the current rendered pixel of the second model, sample multiple channels of the multi-channel shading mask through the shader to obtain the mask value of the current rendered pixel on each channel.

[0058] Specifically, in the GPU rendering pipeline, the shader program processes each pixel of the second model. For the currently rendered pixel, the shader first samples the pixel value at the corresponding position from the multi-channel shading mask based on the texture coordinates of the current rendered pixel. Since the mask texture is multi-channel, a single sampling operation can obtain the mask values ​​of the current rendered pixel in each of the R, G, B, and A channels. For example, a sampled value of (0.8, 0.0, 0.2, 0.0) indicates that the current rendered pixel mainly belongs to the shading region corresponding to the R channel (mask value 0.8), partially belongs to the shading region corresponding to the B channel (mask value 0.2), and does not belong to the shading regions corresponding to the G and A channels.

[0059] Step 002: Based on the mask values ​​on each channel and the synchronized real-time shading parameters, perform shading calculations based on color space transformation on the current rendered pixel.

[0060] Specifically, first, the original color of the current rendered pixel is converted from the RGB color space to the HSV color space. Then, based on the mask value of each channel and the corresponding coloring parameters, the HSV components are weighted and adjusted. For example, if the R channel corresponds to the "hair" region, its coloring parameters are hue shift +30 degrees, saturation increase of 0.1, and lightness unchanged, and the current rendered pixel's mask value in the R channel is 0.8, then the hue value of the current rendered pixel increases by 30 × 0.8 = 24 degrees, and the saturation increases by 0.1 × 0.8 = 0.08. If the current rendered pixel belongs to multiple coloring regions (i.e., the mask values ​​of multiple channels are all greater than 0), then the coloring effects of each channel need to be combined and calculated. Finally, the adjusted HSV color is converted back to the RGB color space to obtain the final coloring result.

[0061] Step 003: Apply the shading calculation results obtained from the shading calculation to the current rendering pixel.

[0062] Specifically, the shader outputs the calculated target color value as the final rendered color of the current pixel, completing the shading process for that pixel. Since the GPU can process a large number of pixels in parallel, the above shading calculation process can complete the processing of all visible pixels in the second model in a very short time, achieving real-time updates to the shading effect.

[0063] All of the above technical solutions can be combined in any way to form optional embodiments of this application, and will not be described in detail here.

[0064] The model coloring method provided in this application achieves millisecond-level synchronization of coloring parameters between the first and second models through a parameter synchronization manager, ensuring color consistency of the same virtual object in different dimensional representations. In addition, pixel-level coloring area control is achieved through multi-channel coloring masking, avoiding color overflow or omission problems that are easy to occur in traditional solutions. The coloring calculation is performed using GPU parallel processing, which can greatly improve performance compared to traditional CPU solutions and can meet the performance requirements of real-time applications such as games.

[0065] The embodiments of this application provide a model coloring method that responds to changes in the coloring parameters of a first model material, obtains updated real-time coloring parameters for the first model material, wherein the first model material corresponds to the first model; synchronizes the real-time coloring parameters to the second model material according to the coloring parameter binding relationship between the first model material and the second model material, wherein the second model material corresponds to the second model, and the first model and the second model are two different dimensions of the same virtual object; and performs real-time coloring processing on the second model based on the synchronized real-time coloring parameters. By establishing a coloring parameter binding relationship between cross-dimensional model materials, the method can synchronize the changing real-time coloring parameters to the other model material when the real-time parameters of one model material change, thus achieving real-time and accurate consistency of the coloring effect of the same virtual object under different dimensional model representations.
