Description

Technical Field

[0001] The present disclosure relates to the field of image processing technology, and in particular to a highlight rendering method, apparatus, computer equipment, and storage medium. Background Art

[0002] When light hits an object, it is reflected into the human eye. The brightest part of the object is called the highlight. When rendering two-dimensional objects such as cartoon characters, highlight rendering is added to improve the rendering effect of the two-dimensional objects after rendering and display.

[0003] In related technologies, when performing highlight rendering, highlight rendering is often only performed based on the current lighting direction. Although this can achieve a more realistic highlight rendering effect, the highlight effect can only be rendered within a fixed range, and the highlight rendering effect of virtual objects such as two-dimensional objects needs to be improved.

[0073] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure.

[0074] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0075] The term "and / or" herein simply describes an association relationship, indicating that three relationships can exist. For example, A and / or B can represent the existence of A alone, the simultaneous existence of A and B, and the existence of B alone. In addition, the term "at least one" herein refers to any combination of at least two of any one or more of a plurality of items. For example, "at least one of A, B, and C" can represent any one or more elements selected from the set consisting of A, B, and C.

[0076] Research has found that when performing highlight rendering, highlight rendering is often only performed based on the current lighting direction. Although this can achieve a more realistic highlight rendering effect, the highlight effect can only be rendered within a fixed range. The highlight rendering effect of virtual objects such as two-dimensional objects needs to be improved.

[0077] Based on the above research, the present disclosure provides a highlight rendering method, device, computer equipment and storage medium. During the highlight rendering process, by adding a material map corresponding to the three-dimensional model of the target object, the final highlight rendering effect is made more realistic, ensuring that the final highlight effect conforms to the reflection law of natural objects; on the other hand, by adding a highlight shape map corresponding to the three-dimensional model of the target object for highlight rendering, the final generated highlight range meets the personalized rendering requirements. Compared with highlight rendering only based on the light direction, the final rendering effect can better meet the user's personalized rendering needs for virtual objects such as two-dimensional objects.

[0078] To facilitate understanding of this embodiment, a highlight rendering method disclosed in an embodiment of the present disclosure is first described in detail. The execution subject of the highlight rendering method provided in the embodiment of the present disclosure is generally a computer device with certain computing capabilities. The computer device includes, for example, a terminal device, a server, or other processing device. The terminal device can be a user equipment (UE), a mobile device, a user terminal, a terminal, etc. In some possible implementations, the highlight rendering method can be implemented by a processor calling computer-readable instructions stored in a memory.

[0079] See also Figure 1 FIG. 1 is a flowchart of a highlight rendering method provided by an embodiment of the present disclosure, wherein the method includes S101 to S103, wherein:

[0080] S101: Obtain a three-dimensional model of a target object, as well as a material map and a highlight shape map corresponding to the three-dimensional model; wherein the highlight shape map is used to describe the highlight shape of the target object when highlight rendering is performed, and the material map is used to describe whether the constituent materials of various parts of the target object are reflective.

[0081] S102: Determine an initial highlight rendering model corresponding to the three-dimensional model based on a lighting direction corresponding to the three-dimensional model and a camera direction corresponding to the three-dimensional model.

[0082] S103: Determine a target highlight rendering model based on the material map, the highlight shape map, and the initial highlight rendering model, and perform highlight rendering based on the target highlight rendering model.

[0083] The following is a detailed description of the above steps.

[0084] For S101, the target object may specifically include a two-dimensional object. Since the two-dimensional object is a virtual object and does not actually exist, the height, fatness and other body characteristics of the two-dimensional object can be determined by constructing a three-dimensional model corresponding to the two-dimensional object, and the determined three-dimensional model can be used to simulate the image that the two-dimensional object wants to present in the real world; the highlight shape map specifically includes a grayscale map, which is composed of pixel points at different grayscale values, and can reflect whether each vertex in the three-dimensional model needs to be highlighted; the material map specifically includes a grayscale map, which is composed of pixel points at different grayscale values, and can reflect whether the constituent material of each vertex in the three-dimensional model is reflective.

[0085] For example, Figure 2a The figure is a schematic diagram of a three-dimensional model of a target object provided by an embodiment of the present disclosure. The three-dimensional model is an artificially constructed virtual model; the three-dimensional model can refine the facial features and clothing features of a person. Figure 2a Different three-dimensional models can be determined for different two-dimensional objects. The three-dimensional models generally include: a plurality of vertices located on the surface of the three-dimensional model, and a mesh formed by interconnected relationships between the vertices.

[0086] For example, Figure 2b , which is a schematic diagram of a highlight shape map provided by an embodiment of the present disclosure. Figure 2b In the figure, the black area is the area that does not need highlight rendering, and the gray area is the area that needs highlight rendering. The highlight shape map can be drawn by the developer, so that the final highlight effect can better meet the personalized rendering needs.

[0087] For example, Figure 2c , which is a schematic diagram of a material map provided by an embodiment of the present disclosure. Figure 2c In the figure, different grayscale values represent different materials of the area. The higher the grayscale value, the higher the reflectivity of the material in the area. The lower the grayscale value, the lower the reflectivity of the material in the area.

[0088] S102: Determine an initial highlight rendering model corresponding to the three-dimensional model based on a lighting direction corresponding to the three-dimensional model and a camera direction corresponding to the three-dimensional model.

[0089] In one possible implementation, Figure 3 As shown, the initial highlight rendering model can be determined by the following steps:

[0090] S301: Determine the normal direction corresponding to each vertex in the three-dimensional model.

[0091] Here, the normal direction of the vertex can be as follows Figure 2a As shown in , for any of the vertices, based on the position information of the vertex in the three-dimensional model, the vertex normal direction corresponding to the vertex can be determined. The normal direction of the vertex can be represented by the vector coordinates in the plane rectangular coordinate system corresponding to the three-dimensional model, for example, the normal direction is (1, 1, 1).

[0092] S302: For any of the vertices, based on the camera direction and lighting direction corresponding to the three-dimensional model and the normal direction corresponding to the vertex, determine the initial highlight rendering information corresponding to the vertex; wherein the initial highlight rendering information is used to describe the illumination intensity of the vertex under the camera direction and the lighting direction, and the initial highlight rendering information corresponding to each vertex constitutes the initial highlight rendering model.

[0093] Here, the camera direction corresponding to the three-dimensional model can be represented by the vector coordinates in the plane rectangular coordinate system corresponding to the three-dimensional model, such as the camera direction a is (0, 0, 1); the lighting direction can be represented by the vector coordinates in the plane rectangular coordinate system corresponding to the three-dimensional model, such as the lighting direction b is (1, 1, 0).

[0094] Specifically, when determining the initial highlight rendering information corresponding to the vertex based on the camera direction, lighting direction and normal direction corresponding to the vertex corresponding to the three-dimensional model, the camera direction and the lighting direction can be superimposed to obtain the target tangent; the target tangent is normalized, and the dot product operation is performed on the normalized target tangent and the normal direction corresponding to the vertex to obtain the initial highlight rendering information corresponding to the vertex.

[0095] For example, taking the camera direction as (0, 0, 1), the lighting direction as (1, 1, 0), and the normal direction of vertex A as (1, 1, 1), the camera direction and the lighting direction are superimposed to obtain a target tangent of (1, 1, 1), and the target tangent after normalization is (1 / 3, 1 / 3, 1 / 3). The normalized target tangent is then click-operated with the normal direction of vertex A to obtain the initial highlight rendering information corresponding to vertex A as 1 / 3×1+1 / 3×1+1 / 3×1=1.

[0096] S103: Determine a target highlight rendering model based on the material map, the highlight shape map, and the initial highlight rendering model, and perform highlight rendering based on the target highlight rendering model.

[0097] In one possible implementation, Figure 4 As shown, the target highlight rendering model can be determined by the following steps:

[0098] S401: Determine an intermediate rendering model based on the material map and the initial highlight rendering model; wherein the intermediate rendering model is used to indicate whether highlights need to be added to various parts of the three-dimensional model.

[0099] In one possible implementation, when determining the intermediate rendering model, the initial highlight rendering information corresponding to each vertex in the initial highlight rendering model can be remapped according to the reflection information stored in the material map to obtain the intermediate highlight rendering information corresponding to each vertex. The intermediate highlight rendering information corresponding to each vertex constitutes the intermediate highlight rendering model.

[0100] Here, when remapping the initial highlight rendering information corresponding to each vertex in the initial highlight rendering model according to the reflection information stored in the material map, an algorithm such as a linear interpolation algorithm can be used to remap the initial highlight rendering information within the range corresponding to the reflection information stored in the material map (that is, the grayscale value range corresponding to the material map) to obtain the intermediate highlight rendering information corresponding to each vertex.

[0101] In this way, remapping the initial highlight rendering model according to the material map can make the final highlight rendering effect more realistic and ensure that the final highlight effect complies with the reflection law of natural objects.

[0102] S402: Determine the target highlight rendering model based on the highlight shape map and the intermediate rendering model.

[0103] In one possible implementation, when determining the target highlight rendering model, the intermediate highlight rendering information corresponding to each vertex in the intermediate rendering model can be remapped according to the highlight shape information stored in the highlight shape map to obtain the target highlight rendering information corresponding to each vertex; the target highlight rendering information corresponding to each vertex constitutes the target highlight rendering model.

[0104] Here, when remapping the intermediate highlight rendering information corresponding to each vertex in the intermediate rendering model according to the highlight shape information stored in the highlight shape map, an algorithm such as a linear interpolation algorithm can be used to remap the initial highlight rendering information within the range corresponding to the highlight shape information stored in the highlight shape map (that is, the grayscale value range corresponding to the highlight shape map) to obtain the target highlight rendering information corresponding to each vertex.

[0105] In this way, by adding a highlight shape map corresponding to the three-dimensional model of the target object for highlight rendering, the final generated highlight range meets the personalized rendering needs. Compared with highlight rendering only based on the light direction, the final rendering effect can better meet the user's personalized rendering needs for virtual objects such as two-dimensional objects.

[0106] In actual applications, the highlight rendering effect often cannot immediately meet the rendering needs of developers. Therefore, after performing highlight rendering based on the target highlight rendering model, a highlight rendering effect adjustment instruction can be received, and highlight rendering can be performed based on the highlight rendering parameter information in the highlight rendering effect adjustment instruction.

[0107] In a possible implementation, highlight rendering parameter information corresponding to the three-dimensional model may be received, and highlight rendering may be performed on the target object based on the target highlight rendering model and the highlight rendering parameter information.

[0108] Here, the highlight rendering parameter information may include at least one of highlight intensity information, highlight range information, and highlight color information.

[0109] Specifically, when adjusting the highlight intensity of the highlight rendering effect, the target highlight rendering information in the target highlight rendering model can be updated based on the highlight intensity parameters carried in the highlight intensity information; when adjusting the highlight range of the highlight rendering effect, the target highlight rendering information in the target highlight rendering model can be updated based on the highlight range parameters carried in the highlight range information; when adjusting the highlight color of the highlight rendering effect, highlight rendering can be performed based on the highlight color corresponding to the highlight color information and the target highlight rendering information in the target highlight rendering model to obtain the highlight rendering effect after adjusting the highlight color.

[0110] For example, the setting page of the highlight rendering parameter information can be as follows: Figure 5 As shown, Figure 5 The adjustment areas for the highlight intensity parameter, highlight range parameter, and highlight color parameter are respectively set, the highlight intensity parameter is set to "0.8", the highlight range parameter is set to "1", and the highlight color is set to "gray".

[0111] In this way, the highlight rendering effect can be adjusted more flexibly by adjusting the highlight rendering parameter information to obtain the desired highlight rendering effect.

[0112] The highlight rendering method provided by the embodiment of the present disclosure makes the final highlight rendering effect more realistic by adding a material map corresponding to the three-dimensional model of the target object during the highlight rendering process, ensuring that the final highlight effect complies with the reflection law of natural objects; on the other hand, by adding a highlight shape map corresponding to the three-dimensional model of the target object for highlight rendering, the final generated highlight range meets the personalized rendering requirements. Compared with highlight rendering based only on the light direction, the final rendering effect can better meet the user's personalized rendering requirements for virtual objects such as two-dimensional objects.

[0113] Those skilled in the art will understand that in the above-mentioned method of the specific implementation method, the writing order of each step does not mean a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

Since the principle of solving the problem by the device in the embodiment of the present disclosure is similar to that of the above-mentioned highlight rendering method in the embodiment of the present disclosure, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.
