[0064] Numerous specific details are set forth in the following description to provide a full understanding of this disclosure. However, this disclosure can be implemented in many other ways than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this disclosure. Therefore, this disclosure is not limited to the specific implementations disclosed below.

[0065] It should be noted that the terms "first," "second," and "third," etc., used in various parts of the embodiments and drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. These terms can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in a sequence other than that illustrated or described herein. The terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that includes 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 devices.

[0066] Non-realistic rendering has become an important part of game development. The core of non-realistic rendering is the model coloring, which involves processing the colors of the model to be colored by gradation. For example, complex colors of various types are classified into a series of fewer color categories. The purpose is to reduce the number of colors and increase the non-realistic feel of the game model. That is, after reducing the number of colors, the model will be more like a cartoon character.

[0067] Existing methods for color gradation of game models are complex and resource-intensive. For example, using texture sampling for color gradation involves one texture per color level, leading to management difficulties and high storage requirements. While ramp textures can express more color details, they suffer from several drawbacks: managing large amounts of ramp texture resources is difficult (textures exist as resources in the project, requiring separate storage and not material storage, necessitating manual management and subject to compression and loading limitations); colors are limited to 0-1, requiring a sampling instruction during shading, resulting in poor performance (the GPU also needs a sampling instruction to obtain the colors within the texture, which is also inefficient); and the user experience is poor, requiring switching between the engine and third-party tools, failing to achieve a WYSIWYG (What You See Is What You Get) interactive effect.

[0068] In the process of coloring game models, to simplify the existing color gradation process and reduce resource consumption, this disclosure provides a color gradation rendering method for models, a corresponding color gradation rendering apparatus for models, an electronic device that can implement the color gradation rendering method for models, and a computer-readable storage medium. The following embodiments provide a detailed description of the above-described method, apparatus, electronic device, and computer-readable storage medium.

[0069] The first embodiment of this disclosure provides a method for rendering a model using color gradation. The main application of this method can be a rendering shader, which can run on a game platform. Figure 1 This is a flowchart of the color gradation rendering method for the model provided in the first embodiment of this disclosure, which is described below in conjunction with... Figure 1 The color gradation rendering method for the model provided in this embodiment will be described in detail. The embodiments described below are used to explain the principle of the method and are not intended to limit actual use.

[0070] S101, obtain the shading effect parameters for the target model to be shaded.

[0071] This step is used to obtain the shading effect parameters for the target model to be shading. These shading effect parameters include color level parameters and position parameters. Color level, or color index, represents the tonal relationship of an image. For example, in an 8-bit RGB digital image, red, green, and blue are represented by 2^8 (256) levels, and the value range of each color is [0, 255]. That is, the color level describes the tonal range of the image from 0 to 255. The color level can determine the color richness and detail of the image. In image processing, adjusting the color level is essentially adjusting the size of different pixel values ​​by adjusting the histogram to improve the visual effect of the image.

[0072] Shading parameters refer to the shading data set before shading the target model. These include level parameters, position parameters, color blending modes, and color categories. Level parameters are the color values ​​of the selected level. For example, in computers, a color is generally represented using RGBA, where R represents the red component, G represents the green component, B represents the blue component, and A represents transparency. These components are typically integers from 0 to 255. These combinations can describe most colors. For example, (255,0,0,255) represents red, and (0,0,255,128) represents blue with half transparency. Position parameters refer to the percentage of the position of the aforementioned level parameters in the target model, and are decimals from 0 to 1. Color blending modes include Fixed mode and Blend mode. Color categories refer to the number of level values ​​in the target model.

[0073] The shading effect parameters include multiple color level parameters and multiple position parameters corresponding to the multiple color level parameters. In this embodiment, obtaining the shading effect parameters for the target model to be shading specifically refers to: in response to a color selection operation based on a visual color level setting component, obtaining the color level parameters and position parameters corresponding to the selected color, wherein the selected color is the color level used for shading the target model. The visual color level setting component allows users to select color levels in a WYSIWYG manner. For example, Gradient's UI components allow users to freely select the color blending mode as Blend or Fixed. When using this component, users can freely drag the position of the color to display different effects, and the data structure of this component is relatively simple, such as... Figure 1-A and Figure 1-B As shown, assuming Figure 1-A or Figure 1-B There are four subscripts, each requiring only four floating-point numbers to store. The first three floating-point numbers represent the three RGB channels of the selected color, and 'a' stores the position parameter from 0 to 1. The four subscripts only require storing 16 floating-point numbers. Using floating-point numbers allows color values ​​to exceed 1, conforming to HDR settings. When the user performs operations on this component (e.g., adding or deleting subscripts, changing the color and position of subscripts, setting the color blending mode to Fixed or Blend), the script passes the corresponding shading effect parameters to the material. During real-time runtime, the material passes these shading effect parameters to the Shader, allowing the Shader code to perform the corresponding color level calculations.

[0074] S102, obtain the model information of the target model.

[0075] This step is used for the Shader to obtain model information of the input target model during real-time runtime. Specifically, it involves obtaining the color attribute information of the target shading point of the target model. The target shading point is any shading point on the target model. The color attribute information of the target shading point has the same data format as the position parameter, that is, the position parameter is a decimal between 0 and 1, and the color attribute information of the target shading point is also a decimal between 0 and 1. The color attribute information of the target shading point can be one of the following: the dot product of the normal unit vector N and the ray unit vector L on the target shading point, NdotL (abbreviated as NL), the hue value corresponding to the target shading point, the saturation value corresponding to the target shading point, the contrast of the target shading point, etc. In this embodiment, NL is used as an example for explanation.

[0076] S103, calculate the color level based on the shading effect parameters and model information to obtain the color level values ​​corresponding to each shading part of the target model.

[0077] After obtaining the shading effect parameters and model information of the target model in the above steps, this step is used to perform color level calculation based on the above shading effect parameters and model information to obtain the color level value corresponding to each shading part of the target model. Specifically, the color level calculation can be performed based on the color attribute information of the target shading point and the shading effect parameters. For example, assuming there are multiple shading points on the target model, the dot product of the normal unit vector N and the light unit vector L of the target shading point is NL, that is, the color attribute information of the target shading point is NL. This step then determines the color level value that the target shading point should be output based on the above shading effect parameters.

[0078] In this embodiment, the above-mentioned calculation of color levels based on the color attribute information of the target color point and the coloring effect parameters can be achieved in the following two ways:

[0079] Method 1: Compare the color attribute information of the target shading point with each of the multiple position parameters, and determine the color level value corresponding to the target shading point based on the comparison results and the value of the color level blending mode. Specifically, this process can be as follows: If the color attribute information of the target shading point is greater than the first position parameter and less than the second position parameter, and the color level blending mode is set to Fixed, then the color level value corresponding to the target shading point is determined to be the color level parameter corresponding to the second position parameter; or, if the color attribute information of the target shading point is greater than the first position parameter and less than the second position parameter, and the color level blending mode is set to Blend, then an interpolation operation is performed based on the first position parameter, the second position parameter, and the color attribute information of the target shading point, and the resulting interpolation result is determined as the color level value corresponding to the target shading point; wherein the first position parameter and the second position parameter are adjacent position parameters.

[0080] like Figure 1-CAs shown, the above process can be described as follows: Since NL is the dot product of two unit vectors of the target shading point, the range of NL is [0,1]. This range of values ​​is compared with the color level indices one by one. i cycles from 1 to count, where count is the number of color level indices (color level types), and CK[i] represents the color level parameter and position parameter in the i-th color level index. t1 represents the previous color level index, and t2 represents the current color level index. If the value of NL is between the position parameters of t1 and t2, that is, NL is greater than or equal to t1.a (the position parameter of t1) and NL is less than or equal to t2.a (the position parameter of t2), then the color (color level value) output by the target shading point should be composed of the colors between i and i-1. If the value of the color level blending mode BM is Fixed, then the color level value (t2.rgb) corresponding to the i-th color level index is directly returned as the color level value of the target shading point. If BM is set to Blend, then the color level value corresponding to the i-th color level index is interpolated with the color level value corresponding to the (i-1)-th color level index. The interpolation formula is: P = (NL - t1.a) / (t2.a - t1.a). The final color level value of the target shading point is: t1.rgb + (t2.rgb - t1.rgb) * P. The GPU's shaderlerp instruction can describe the interpolation formula, so the lerp instruction can be used directly to replace the interpolation calculation process.

[0081] Method 2: Multiple matrices are used to represent the multiple positional parameters, and the `step` and `lerp` instructions are used to perform parallel calculations on these matrices to obtain the target matrix corresponding to the target shading point, and the color level value corresponding to the target matrix is ​​calculated. Due to the special nature of the GPU architecture, loops and conditional statements can significantly impact runtime efficiency during low-level operation. To optimize Method 1, Method 2 optimizes the Shader instruction set. Its main idea is to avoid using conditional and loop statements throughout the Shader implementation, utilizing the computational instructions provided by the GPU hardware. It employs a matrix approach and avoids using GPU loops and conditional statements, using only simple addition, subtraction, multiplication, and division instructions to achieve parallel GPU computation, thereby accelerating computation. Figure 1-DAs shown, this process is mainly optimized by 2x4 matrix multiplication instructions. Because GPU computing is parallel, matrix multiplication can greatly accelerate the entire calculation process. At the beginning of the program, T 2x4 matrices are defined. The meaning of each matrix is ​​the color level parameter and position parameter of the first color level index and the color level parameter and position parameter of the second color level index. This series of matrices is defined as the M[i] matrix. A total of T matrices are defined. M[0] represents the color position of the 0th index, and M[T-1] represents the color position of the last index. Next, the step instruction is used to replace the if condition judgment instruction. Because the step instruction has the characteristic of returning 1 if a <= b, otherwise returning 0, the step instruction can be used to determine whether the NL of the target shading point is less than the position parameter of the nth index. Then, the step instruction is combined with the lerp instruction for calculation. If step returns 0, it means taking the value before lerp. If step returns 1, it means taking the value after lerp. Through continuous lerp and step calculations, the final value of step 1 is taken as the result and stored in FC. The final FC obtains the corresponding M matrix. After obtaining the corresponding M matrix, the color level values ​​are interpolated again on the first and second rows of the M matrix to obtain the color level values ​​corresponding to the NL output.

[0082] S104 renders the target model based on color level values.

[0083] After calculating the color level values ​​corresponding to each shading part of the target model in the above steps, in this step, the shader can render the target model based on the above color level values. For example, after obtaining the color level values ​​of the target shading points of the target model, the target shading points can be rendered based on the color level values.

[0084] The color gradation rendering method for the model provided in this disclosure only requires storing a few color gradation indices during color gradation processing, making storage simple. The desired output gradation effect parameters are set through a visual color gradation setting component. This component allows users to set color gradation effects in a WYSIWYG manner. For example, the Gradient UI component allows users to freely select the color blending mode as Blend or Fixed. When using this component, users can freely drag the color positions to display different color gradation effects. Furthermore, the data structure of the gradation effect parameters obtained through this component is relatively simple. These gradation effect parameters, along with the model information of the target model (color attribute information of the target gradation points), can be input into the shader. The color gradation values ​​are calculated using the calculation methods described in Method 1 or Method 2 above. Based on these color gradation values, the model is rendered to obtain the gradation target model.

[0085] It should be noted that although gradation is widely used in non-realistic rendering, non-realistic rendering is only used as an example to explain this method. That is, this method is not limited to non-realistic rendering scenarios. In practice, this method can be applied to any scenario that uses gradation, such as subsurface scattering of skin in realistic rendering.

[0086] This method is relatively simple to implement and is not limited to any particular engine, nor is it limited to forward rendering or deferred rendering. It can maximize the performance of the graphics and make the process of color gradation of game models simpler and more efficient.

[0087] Furthermore, after the instruction set optimization of Method 2 above, a better performance calculation result can be obtained. Since the above calculation process is relatively simple, and the acquisition methods and approaches of the data it depends on (shading effect parameters, color attribute data of target shading points) are relatively simple and efficient, the above method has high scalability (this method can be ported to other platforms and can be implemented in any game engine).
