[0058] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.
[0059] Conventional cartoon rendering usually uses numerical remapping of Lambert lighting results when transitioning between light and dark, thus forming a binary light and shadow effect with obvious color block transitions, for example Figure 1 As shown, a rendering effect with clear light and shadow transition and distinct color blocks is obtained. However, this method obviously cannot achieve the rendering effect of watercolor brushstrokes.
[0060] Therefore, an embodiment of the present application provides a model rendering method, which is used to solve the above-mentioned problem. The method can be generated by any electronic device with computing and processing capabilities. The electronic device can be, for example, a terminal-oriented computer device or a back-end server.
[0061] The model rendering method provided in this application is specifically described below through multiple examples in conjunction with the accompanying drawings.
[0062] Figure 2 One of the flow diagrams of the model rendering method provided in the embodiment of the present application is as follows: Figure 2 As shown, the method includes:
[0063] S101 , performing illumination rendering on a to-be-rendered object model to obtain basic light and shadow transition information of the to-be-rendered object model.
[0064] First, the object model to be rendered is subjected to illumination rendering to obtain basic light and shadow transition information of the object model to be rendered. The object model to be rendered can be a sphere (or a 3D animation character model described below, the sphere is only used as an example and does not mean that the object model to be rendered can only be a sphere). The basic light and shadow transition information obtained is as follows: Figure 3 As shown, Figure 3 0 represents the dark side, and 1 represents the bright side, that is, 0, 0.25, 0.5, 0.75, 1 represent a uniform transition from the dark side to the bright side. Figure 3 It presents a light and shadow transition effect of alternating light and dark.
[0065] Specifically, a preset light and shadow transition illumination model can be used to calculate the illumination information to be rendered of the object model to be rendered, and then based on the calculated illumination information to be rendered, diffuse reflection illumination rendering is performed on the object model to be rendered to obtain basic light and shadow transition information of the object model to be rendered, wherein the light and shadow transition illumination model is a semi-Lambert illumination model, and the semi-Lambert illumination model uses a semi-Lambert algorithm to calculate the illumination information to be rendered. The semi-Lambert algorithm is as shown in formula (1):
[0066] dot(N,L)*0.5+0.5(1)
[0067] Among them, dot is a mathematical dot product operation, N is the surface normal information of the object model to be rendered, and L is the lighting direction information.
[0068] S102: Use a preset watercolor map to perform texture rendering on the object model to be rendered, and obtain watercolor texture noise information of the object model to be rendered.
[0069] In this embodiment, a preset watercolor map can be used to perform texture rendering on the object model to be rendered, and watercolor texture noise information of the object model to be rendered can be obtained. The obtained watercolor texture noise information is as follows: Figure 4 As shown, Figure 4 It presents a watercolor blending effect.
[0070] S103 , mixing the basic light and shadow transition information and the watercolor texture noise information to obtain the watercolor shading transition information of the object model to be rendered.
[0071] Then the basic light and shadow transition information and the watercolor texture noise information are mixed to obtain the watercolor blending transition information of the object model to be rendered. The watercolor blending transition information includes both the light and shadow transition effect of alternating light and dark and the watercolor blending effect.
[0072] S104: Obtain a target object model corresponding to the object model to be rendered according to the watercolor blending transition information.
[0073] Finally, according to the watercolor shading transition information, the object model to be rendered is rendered, wherein the object model to be rendered may be, for example, a three-dimensional animation character, such as Figure 5 As shown, the target object model corresponding to the object model to be rendered is obtained, that is, the final rendering effect of the three-dimensional animation character includes both the light and shadow transition effect of alternating light and dark and the watercolor blending effect.
[0074] In summary, the embodiment of the present application provides a model rendering method, which mixes basic light and shadow transition information and watercolor texture noise information to obtain watercolor blending transition information of the object model to be rendered, and then renders the object model to be rendered using the watercolor blending transition information. The target object model finally obtained includes a light and shadow transition effect of watercolor blending, which improves the quality of stylized rendering.
[0075] Figure 6 The second flow chart of the model rendering method provided in the embodiment of the present application is as follows: Figure 6 As shown, the use of a preset watercolor map to perform texture rendering on the object model to be rendered in S102 to obtain watercolor texture noise information of the object model to be rendered may include:

[0077] By using a preset watercolor map and performing texture mapping according to the spatial coordinates of the object model to be rendered, the texture information of each position point on the surface of the object model to be rendered can be obtained.
[0078] S202 , performing linear interpolation on the texture information of each position point to obtain the watercolor texture noise information of each position point.
[0079] After obtaining the texture information of each position point on the surface of the object model to be rendered, the texture information of each position point is linearly interpolated to obtain the watercolor texture noise information of each position point.
[0080] Specifically, Figure 7 The third flow chart of the model rendering method provided in the embodiment of the present application is as follows: Figure 7 As shown, the use of a preset watercolor map to perform texture mapping on the object model to be rendered in S201 to obtain texture information of each position point on the surface of the object model to be rendered may include:

[0082] First, obtain the three-dimensional normal coordinates of the preset three-dimensional space where the object model to be rendered is located, represented by the first coordinate direction x, the second coordinate direction y, and the third coordinate direction z, and then three planes can be obtained, namely the first plane (xy plane) formed by the x direction and the y direction, the second plane (yz plane) formed by the y direction and the z direction, and the third plane (xz plane) formed by the x direction and the z direction, and these three planes are perpendicular to each other.
[0083] Using the preset watercolor map, according to the 3D normal coordinates of the object model to be rendered, texture mapping is performed on the three perpendicular planes in the preset 3D space in turn for the object model to be rendered. That is, texture mapping is performed on the xy plane, xz plane and yz plane respectively, and the texture information of each position point in the xy plane, xz plane and yz plane can be obtained, which are represented by worldnoise_xy, worldnoise_xz and worldnoise_yz respectively.
[0084] Then S202 performs linear interpolation on the texture information of each position point to obtain the watercolor texture noise information of each position point, including:
[0085] S302 , performing linear interpolation on texture information of each position point in three planes to obtain texture noise information of each position point in three planes.

Perform linear interpolation on texture information of each position point on a first plane and a second plane along a first coordinate direction to obtain texture noise information of each position point on the first plane and texture noise information of each position point on the second plane.
[0088] Along the first coordinate direction (x direction), linear interpolation is performed on the texture information of each position point on the first plane (xy plane) and the second plane (yz plane). That is, linear interpolation is performed on the texture information worldnoise_xy of each position point on the first plane and the texture information worldnoise_yz on the second plane. The texture noise information of each position point on the first plane and the texture noise information on the second plane can be obtained, which is represented by mix_a, as shown in Fig. 9 shown.
[0089] Among them, the value of 1 represents the texture noise information mapped on the first plane (xy plane), and the value of 0 represents the texture noise information mapped on the second plane (yz plane).
[0090] S402 . Perform linear interpolation on texture information of each position point on the third plane along the second coordinate direction to obtain texture noise information of each position point on the third plane.
[0091] Then, after obtaining mix_a, linear interpolation is performed on the texture information (worldnoise_xz) of each position point on the third plane along the second coordinate direction (y direction), and mix mix_a with worldnoise_xz to obtain the texture noise information of each position point on the third plane, such as Fig.10 As shown, the value of 1 represents the texture noise information mapped by the third plane (xy plane), and the value of 0 represents the texture noise information mapped by mix_a.
[0092] It should also be noted that, in the present embodiment, the first coordinate direction (x direction) and the second coordinate direction (y direction) are respectively two coordinate directions of the first plane (xy plane).
[0093] S303 , mixing the texture noise information of each position point in three planes to obtain the watercolor texture noise information of each position point.
[0094] Finally, after obtaining the texture noise information of each position point in the three planes, the texture noise information of each position point in the three planes is mixed to obtain the watercolor texture noise information of each position point, such as Figure 4 shown.
[0095] Fig.11 A fifth flow chart of the model rendering method provided in the embodiment of the present application is as follows: Fig.11 As shown, the step of mixing the basic light and shadow transition information and the watercolor texture noise information to obtain the watercolor shading transition information of the object model to be rendered in step S103 may also include:
[0096] S501 , using a preset smooth transition function to process basic light and shadow transition information to obtain target light and shadow transition information of the object model to be rendered.
[0097] The preset smooth transition function may be, for example, a SmoothStep algorithm. Figure 3 By processing the basic light and shadow transition information shown in FIG. 1 , the target light and shadow transition information of the object model to be rendered can be obtained, such as Fig.12 shown.
[0098] Among them, a preset smooth transition function is used to process the basic light and shadow transition information, for example, it may include: Figure 3 The result is remapped to make the light and shadow transition effect more distinct. Figure 3 and Fig.12 , 0 represents the dark side, 1 represents the bright side, and the SmoothStep algorithm is used to Figure 3 The result of remapping is Fig.12 There are more numerical ranges marked with 0 and 1, making the transition between the bright and dark sides more distinct.
[0099] S502 : Mix the target light and shadow transition information and the watercolor texture noise information to obtain the watercolor shading transition information of the object model to be rendered.
[0100] Will Fig.12 The target light and shadow transition information shown and Figure 4 Mix the watercolor texture noise information shown in the figure to get Fig.13 The watercolor shading transition information of the object model to be rendered is shown as Fig.13 As shown, in the watercolor blending transition information obtained in this way, the transition between the bright side and the dark side is clearer, and the watercolor blending effect is included, which further improves the rendering quality of the stylized rendering project.
[0101] In one embodiment, the target object model corresponding to the object model to be rendered may also be obtained according to preset color transition information and watercolor blending transition information.
[0102] The preset color transition information may be a color attribute bar composed of multiple colors, for example, a color attribute bar composed of yellow and orange. By making a one-to-one correspondence between the preset color transition information and the grayscale value of the light and shadow transition effect in the watercolor blending transition information, the watercolor blending transition information may be filled with color so that the target object model finally obtained has color. The preset color transition information may be adjusted according to actual needs and is not limited here.
