[0029] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0030] In one embodiment of the present application, a method for rendering the face of a virtual character can be run on a local terminal device or a server. When a method for rendering the face of a virtual character is run on a server, the method can be implemented and executed based on a cloud interaction system, wherein the cloud interaction system includes a server and a client device.
[0031] In a possible implementation, an embodiment of the present invention provides a method for facial rendering of a virtual character, providing a user interface through a terminal device, wherein the terminal device may be the local terminal device mentioned above, or may be a client device in the cloud interaction system mentioned above.
[0032] A method for rendering the face of a virtual character provided in an embodiment of the present application is implemented using UE (Unreal Engine).
[0033] Figure 1 This is a flow chart of a method for rendering the face of a virtual character provided in an embodiment of the present application. Figure 1 As shown, the method includes:
[0034] S101 . In response to a rendering instruction for a target virtual character, determine a to-be-rendered area in a facial area of the target virtual character.
[0035] When performing facial rendering on a virtual character, the developer issues a rendering instruction for the target virtual character and determines the area to be rendered in the facial area of the target virtual character.
[0036] For example, if the rendering effect is a blush effect, the area to be rendered is a cheek area of the facial area.
[0037] S102, adjusting rendering parameters of two preset facial blush maps.
[0038] Before the facial rendering process, two preset facial blush maps are prepared in advance. The two preset facial blush maps are exactly the same map. During the facial rendering process, the two preset facial blush maps can set the same rendering parameters or different rendering parameters.
[0039] Furthermore, before adjusting the rendering parameters of the two preset facial blush maps, first select the two preset facial blush maps, and embed the material function of the facial blush maps into the facial material instance of the target virtual character. In this way, the rendering parameters of the facial blush maps can be displayed in the facial material instance, and the rendering parameters of the two preset facial blush maps can be adjusted.
[0040] S103: Merge the two adjusted facial blush maps to generate a target facial blush map.
[0041] The two adjusted facial blush maps can present different / same blush effects. By merging the two adjusted facial blush maps, the two different / same blush effects can be superimposed to present a richer blush effect. The blush effect of the target facial blush map can be more selective. This rich blush effect cannot be presented by a single blush map.
[0042] For example, the black and white areas of the facial blush map are separated by a Lerp node, and the two facial blush maps are merged together again by the algorithm of the Lerp node.
[0043] S104, using the target facial blush map to render the to-be-rendered area of the target virtual character, so that the rendered area presents a facial blush effect corresponding to the target facial blush map.
[0044] The blush effect of the target facial blush map is richer. The rich target facial blush map is rendered to the to-be-rendered area of the target virtual character. The rendering area can present the facial blush effect corresponding to the target facial blush map, thereby making the rendering effect of the target virtual character richer.
[0045] Therefore, by designing a facial blush map with rich blush effects, the blush rendering effect is made richer, and the applicability and versatility of the facial blush map are expanded, thereby improving the rendering effect of the virtual character.
[0046] In summary, in the implementation of this city, in response to the rendering instruction for the target virtual character, the area to be rendered in the facial area of the target virtual character is determined; the rendering parameters of the two preset facial blush maps are adjusted; the two adjusted facial blush maps are merged to generate a target facial blush map; the target facial blush map is used to render the area to be rendered of the target virtual character, so that the rendered area presents the facial blush effect corresponding to the target facial blush map. Thus, a facial blush map with rich blush effects is designed through two preset facial blush maps, which makes the blush rendering effect richer, expands the applicability and versatility of the facial blush map, and improves the rendering effect of the virtual character.
[0047] In the above Figure 1 On the basis of the corresponding embodiment, in another embodiment of the present application, adjusting the rendering parameters of two preset facial blush maps in S102 includes:
[0048] According to the first adjustment operation on the preset facial blush map, the display configuration information of the blush object in the preset facial blush map is adjusted; and / or,
[0049] According to the second adjustment operation on the preset facial blush map, the mapping configuration information of the blush object in the preset facial blush map is adjusted.
[0050] When a preset facial blush map is obtained, the preset facial blush map contains display configuration information of the blush object. By adjusting the display configuration information, the display information of the blush is enriched.
[0051] By adjusting the mapping configuration information, the blush effect of the preset facial blush map is made more accurate. For example, the mapping configuration information is UV mapping information. The UV coordinate system is two-dimensional, with the horizontal direction called U and the vertical direction called V. Through the UV coordinate system, any pixel on the image can be located. In 3D modeling, the UV coordinates define the position information of each point on the image. These points are interconnected with the 3D model to determine the position of the surface texture map.
[0052] In summary, in the implementation of this city, according to the first adjustment operation on the preset facial blush map, the display configuration information of the blush object in the preset facial blush map is adjusted; and / or, according to the second adjustment operation on the preset facial blush map, the mapping configuration information of the blush object in the preset facial blush map is adjusted. Thus, a rich blush effect is accurately displayed.
[0053] Based on the above embodiment, in another embodiment of the present application, the display configuration information of the blush object includes at least one of: a mask image of the blush object, a mask strength parameter of the mask image, and a color parameter of the blush object.
[0054] For example, the mask image of the blush object is a Mask map, the mask image represents the shape of the blush, the mask intensity parameter represents the intensity of the blush, and the color parameter of the blush object represents the color of the blush.
[0055] The mapping configuration information of the blush object includes at least one of the following information: the position information of the blush object, the scaling information of the blush object, and the rotation information of the blush object.
[0056] For example, the position information and scale information of the blush object are organized together through the Float4 node, and the rotation information of the blush object is connected in series and applied to the facial UV, so as to accurately render the blush object to the area to be rendered.
[0057] In summary, in the implementation of this city, the display configuration information of the blush object includes at least one of the following information: the mask map of the blush object, the mask strength parameter of the mask map, and the color parameter of the blush object; the mapping configuration information of the blush object includes at least one of the following information: the position information of the blush object, the scaling information of the blush object, and the rotation information of the blush object. Thus, the rich blush effect can be accurately rendered to the area to be rendered.
[0058] In the above Figure 1 On the basis of the corresponding embodiment, the embodiment of the present application also provides another method for rendering the face of a virtual character. Figure 2 A flowchart of another method for rendering the face of a virtual character provided in an embodiment of the present application. Figure 2As shown, before using the target facial blush map to render the to-be-rendered area of the target virtual character in S104, the method further includes:
[0059] S201, obtaining a preset blush detail map.
[0060] In order to make the facial blush richer, you can add a preset blush detail map on the basis of the blush.
[0061] For example, the preset blush detail map may be a red line map. By adding the red line map, the blush has red lines, and the blush effect will be more realistic and rich.
[0062] In S104, the target facial blush map is used to render the to-be-rendered area of the target virtual character, including:
[0063] S202: Merge the preset blush detail map and the target facial blush map to generate a target facial map.
[0064] For example, in order to avoid deformation of the blush detail map caused by the target facial animation, a patch model is provided in this embodiment, and the preset blush detail map is equipped on the target face on the blueprint using the patch model.
[0065] The target face map with the added preset blush detail map has a richer blush effect.
[0066] S203: Rendering the target virtual character's to-be-rendered area using the target facial map, so that the rendered area presents a facial rendering effect corresponding to the target facial map.
[0067] The facial rendering effects include: a facial blush effect corresponding to a target facial blush map, and a facial blush detail effect corresponding to a preset blush detail map.
[0068] The target facial map with the preset blush detail map added is rendered to the to-be-rendered area of the target virtual character. The rendered area can present the facial blush effect corresponding to the target facial blush map, thereby making the rendering effect of the target virtual character richer.
[0069] Therefore, the facial blush map includes blush details, making the blush rendering effect richer, and also expanding the applicability and versatility of the facial blush map, thereby improving the rendering effect of the virtual character.
[0070] In summary, in the implementation of this city, a preset blush detail map is obtained; the preset blush detail map and the target facial blush map are merged to generate a target facial map; the target facial map is used to render the target virtual character's to-be-rendered area, so that the rendered area presents the facial rendering effect corresponding to the target facial map, and the facial rendering effect includes: the facial blush effect corresponding to the target facial blush map, and the facial blush detail effect corresponding to the preset blush detail map. Thus, the facial blush map contains blush details, making the blush rendering effect richer, and also expanding the applicability and versatility of the facial blush map, and improving the rendering effect of the virtual character.
[0071] In the above Figure 2 On the basis of the corresponding embodiment, the embodiment of the present application also provides another method for adjusting facial rendering of a virtual character. Figure 3 A flowchart of another method for adjusting the facial rendering of a virtual character provided in an embodiment of the present application. Figure 3 As shown, before merging the preset blush detail map and the target facial blush map to generate the target facial map in S202, the method further includes:
[0072] S301. According to a third adjustment operation on a preset blush detail map, adjusting mapping configuration information of a blush detail object in a preset blush detail map.
[0073] By adjusting the mapping configuration information, the blush detail effect of the preset blush detail map is made more accurate.
[0074] And / or, S302, according to a fourth adjustment operation on the preset blush detail map, adjusting the display configuration information of the blush detail object in the preset blush detail map.
[0075] When a preset blush detail map is obtained, the preset blush detail map contains display configuration information of the blush detail. By adjusting the display configuration information, the display information of the blush detail is made richer.
[0076] In S202, the preset blush detail map and the target facial blush map are merged to generate the target facial map, including:
[0077] S303: Merge the adjusted blush detail map and the target facial blush map to generate a target facial map.
[0078] The adjusted blush detail map is more in line with the development needs of developers. The target facial map with the adjusted blush detail map added is rendered to the to-be-rendered area of the target virtual character. The rendering area can present the facial blush effect corresponding to the target facial blush map, thereby making the rendering effect of the target virtual character richer.
[0079] In this embodiment, there is no order between step S301 and step S302, and the steps in this embodiment are only examples.
[0080] In summary, in the implementation of this city, according to the third adjustment operation on the preset blush detail map, the mapping configuration information of the blush detail object in the preset blush detail map is adjusted; and / or, according to the fourth adjustment operation on the preset blush detail map, the display configuration information of the blush detail object in the preset blush detail map is adjusted; the adjusted blush detail map and the target facial blush map are merged to generate the target facial map. Therefore, the facial blush map contains blush details, making the blush rendering effect richer.
[0081] In the above Figure 3 On the basis of the corresponding embodiment, in another embodiment of the present application, the mapping configuration information of the blush detail object includes at least one of: position information of the blush detail object, scaling information of the blush detail object, and rotation information of the blush detail object.
[0082] For example, the position information and scale information of the blush detail object are organized together through the Float4 node, and the rotation information of the blush detail object is connected in series and applied to the facial UV, so as to accurately render the blush detail object to the area to be rendered.
[0083] The display configuration information of the blush detail object includes at least one of: a mask image of the blush detail object, a mask strength parameter of the mask image, and a color parameter of the blush detail object.
[0084] For example, the mask map of the blush object is a Mask map. The mask map represents the shape of the blush, the mask intensity parameter represents the intensity of the blush, and the color parameter of the blush object represents the color of the blush. The mask module of the Mask map is connected to the DitherTemporalAA node to make the blush detail object achieve a semi-transparent effect, making the blush more vivid and more in line with the real blush effect.
[0085] In summary, in the implementation of this city, the mapping configuration information of the blush detail object includes at least one of the following information: the location information of the blush detail object, the scaling information of the blush detail object, and the rotation information of the blush detail object; the display configuration information of the blush detail object includes at least one of the following information: the mask map of the blush detail object, the mask strength parameter of the mask map, and the color parameter of the blush detail object. Thus, the blush is more vivid and more in line with the real blush effect.

[0088] After obtaining the preset facial basic color map, the configuration parameters of the preset facial basic color map are adjusted according to the blush design requirements, so that a variety of facial basic color maps can be achieved to facilitate the generation of facial blush maps.
[0089] S402: Generate a preset facial blush map according to the adjusted facial basic color map, the mask map of the preset blush object, and the display configuration parameters of the preset blush object.
[0090] According to the blush design requirements, a variety of different facial blush maps can be generated in a diversified manner. Pre-generate preset facial blush maps so that they can be used directly during facial rendering to improve facial rendering efficiency.
[0091] In summary, in the implementation of this city, the configuration parameters of the preset facial basic color map are obtained and adjusted; the preset facial blush map is generated according to the adjusted facial basic color map, the mask map of the preset blush object, and the display configuration parameters of the preset blush object. Thus, the preset facial blush map is generated in advance so that it can be directly used when performing facial rendering, thereby improving the efficiency of facial rendering.
[0092] In the above Figure 2 On the basis of the corresponding embodiment, the embodiment of the present application also provides a method for pre-generating a preset blush detail map.

[0096] According to the requirements of blush detail design, a variety of different blush detail maps can be generated in a diversified manner. Pre-generate a preset face blush detail map so that it can be directly used when rendering the face, thereby improving the efficiency of facial rendering.
[0097] In summary, in the implementation of this city, the configuration parameters of the preset facial basic color map are obtained and adjusted; the preset blush detail map is generated according to the adjusted facial basic color map, the mask map of the preset blush detail object, and the display configuration parameters of the preset blush detail object. Thus, the preset facial blush detail map is generated in advance so that it can be directly used when performing facial rendering, thereby improving the efficiency of facial rendering.

[0100] S602: According to the target key points of the facial region, a preset facial mask image is associated with the target key points of the facial region to obtain a region to be rendered.
[0101] For example, when performing facial rendering, target key points are calibrated in the head bone part, and the parent item in the patch model corresponding to the preset facial mask image selects the target key points, so that the area to be rendered consisting of the target key points and the preset facial mask image can be obtained.
[0102] In summary, in the implementation of this city, a preset facial mask image is obtained; according to the target key points of the facial area, the preset facial mask image is associated with the target key points of the facial area to obtain the area to be rendered.
