Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of image processing, in particular to a graphics rendering method and device, electronic equipment and computer readable storage medium. BACKGROUND

[0002] In graphics rendering, there are usually many presentations of wrinkled surfaces, such as moss, soil piles, and rock surfaces. That is, improving the display effect of the wrinkled surface (i.e., improving the expressiveness of the wrinkled surface) can improve the authenticity and expressiveness of the graphics.

[0003] There are mainly two ways to improve the display effect of the wrinkled surface in the existing graphics rendering, one is to improve the intensity of the normal line, and the other is to increase the number of surfaces of the model.

[0004] However, the two wrinkled surface effect improvement methods currently have obvious problems. First, when the display effect of the wrinkled surface is improved by improving the intensity of the normal line, the wrinkled effect is closely related to the light direction, so there is a problem that the wrinkled effect can only be shown in the place where the light shines and it is difficult to express the wrinkled effect in the dark. Second, when the display effect of the wrinkled surface is improved by increasing the number of surfaces of the model, the increase in the number of model surfaces will cause high memory, and thus cause the problem of excessive graphics rendering pressure.

[0078] The following will be described in detail respectively. It should be noted that the serial numbers of the following embodiments are not regarded as the limitation of the preferred order of the embodiments.

[0079] Reference Figure 1 , Figure 1 is a flowchart of a graphic rendering method provided by an embodiment of the present application. It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here, for example, step 101 can be executed before step 102, or step 102 can be executed before step 101, or steps 101 and 102 can be executed simultaneously. In the present embodiment, the graphic rendering method comprises steps 101-104, wherein:

[0080] 101. Based on a color map of a to-be-rendered wrinkled surface, obtain the basic color of each pixel of the to-be-rendered wrinkled surface.

[0081] The to-be-rendered wrinkled surface is the surface of a virtual object that needs to be rendered with a wrinkled effect, for example, moss, soil pile, rock surface, etc.

[0082] The color map is a map used to store the color of a surface in graphic rendering, and in the present embodiment, the color map is specifically used to store the basic color of each pixel of the to-be-rendered wrinkled surface. For example, the color map of the to-be-rendered wrinkled surface can be a Diffuse Map, Albedo, Base Color, etc.

[0083] In step 101, the basic color of each pixel is extracted from the color map of the to-be-rendered wrinkled surface when the wrinkled surface is rendered.

[0084] 102. Based on a normal map of the to-be-rendered wrinkled surface, obtain the normal of each pixel of the to-be-rendered wrinkled surface.

[0085] The normal map is an application of the bump mapping technique, and the normal map stores the normal of the surface, and is specifically used to store the normal of each pixel of the to-be-rendered wrinkled surface. Since the direction is a relative coordinate space, there are three different normal maps in the graphic rendering: the tangent space normal map, the object space normal map, and the world space normal map. The three normal maps have respective advantages and disadvantages and can achieve the same effect, only the calculation method is different.

[0086] The world space normal map is a normal map based on global coordinates.

[0087] The object space (or model space) normal map is based on the entire object rather than each face.

[0088] The tangent space normal is based on the tangent direction of each face. The normal map in the tangent space is the most common form of normal map. In this paper, the normal map in the tangent space is taken as an example to illustrate the graphic rendering method of the embodiments of the application, as shown in Figure 2 Figure 2 is a schematic diagram of the normal of the to-be-rendered wrinkled surface in the embodiments of the application. The normal map stores the normal of each pixel on the to-be-rendered wrinkled surface.

[0089] In step 101, the normal of each pixel is extracted from the normal map of the to-be-rendered wrinkled surface when the wrinkled surface is rendered.

[0090] 103. Obtain the final rendering color of each pixel of the to-be-rendered wrinkled surface according to the normal of each pixel, the camera direction vector of the rendering camera of the to-be-rendered wrinkled surface, and the basic color of each pixel.

[0091] The final rendering color of each pixel is used to reflect the visual included angle constructed between the normal of each pixel and the camera direction vector.

[0092] The normal of each pixel and the camera direction vector are used to construct the visual included angle between each pixel and the rendering camera, and the final rendering color of each pixel is specifically used to act the visual included angle between each pixel and the rendering camera on the basic color of each pixel.

[0093] The rendering camera is a camera used to render the to-be-rendered wrinkled surface. For example, if the to-be-rendered wrinkled surface is a moss surface in a game scene, the game camera of the moss surface in the game scene is the rendering camera of the to-be-rendered wrinkled surface.

[0094] The camera direction vector refers to a representation vector of the direction of the rendering camera.

[0095] ​There are various ways to determine the final rendering color of each pixel of the wrinkled surface to be rendered in step 103, exemplarily including:

[0096] (I) First, determine the orientation degree of each pixel to the rendering camera, and then apply the orientation degree to the color map to obtain the final rendering color. At this time, step 103 can specifically include steps 1031A-1032A as follows:

[0097] 1031A, according to the normal of each pixel and the camera direction vector, obtaining the relative position between each pixel and the rendering camera.

[0098] Wherein, the relative position between each pixel and the rendering camera is used to indicate the degree of each pixel facing or facing away from the rendering camera.

[0099] There are various ways to determine the relative position of each pixel in step 1031A, exemplarily including:

[0100] ①The degree of each pixel facing the rendering camera (i.e. the camera orientation degree of each pixel) is used as the relative position between each pixel and the rendering camera. At this time, step 1031A can specifically include steps A1-A2 as follows:

[0101] A1, according to the dot product of the normal of each pixel and the camera direction vector, obtaining the camera orientation degree of each pixel.

[0102] Wherein, the camera orientation degree of each pixel is used to reflect the degree of each pixel facing the rendering camera. By changing the camera orientation degree of each pixel, the visual angle between each pixel and the rendering camera can be enhanced or weakened, and the basic color of each pixel is affected, thereby showing the richness of the wrinkled surface.

[0103] As shown in Figure 3 , Figure 3is a schematic diagram of a visual angle between a normal of each pixel and a rendering camera provided in an embodiment of the present application, a dot product of the normal of each pixel and a camera direction vector (denoted as "dot(Normal, CameraVector)") is equivalent to a dot product of two vectors (the normal vector and the camera direction vector), and the dot product of vectors can be used to describe an included angle between two directions in graphics rendering. Therefore, the dot product of the normal of each pixel and the camera direction vector ("dot(Normal, CameraVector)") reflects a degree to which each pixel faces the rendering camera; the dot product of the normal of each pixel and the camera direction vector is multiplied by a facing coefficient (denoted as "K1") again, and by adjusting a size of the facing coefficient K1, the degree to which each pixel faces the rendering camera can be adjusted to represent a richness of the wrinkled surface. As shown in the following formula (1), the normal of each pixel, the camera direction vector, and a preset facing formula can be substituted into the preset facing formula to directly calculate the degree to which each pixel faces the camera. At this time, the step A1 can specifically include: calculating the degree to which each pixel faces the camera according to the normal of each pixel, the camera direction vector, and the preset facing formula. Similarly, the degree to which each pixel in the wrinkled surface to be rendered faces the camera can be obtained. The preset facing formula is as follows:

[0104] P1 = K1 * dot(Normal, CameraVector) Formula (1)

[0105] In formula (1), dot(Normal, CameraVector) represents the dot product of the normal of each pixel and the camera direction vector, K1 is a facing coefficient, K1 is used to adjust the degree to which each pixel faces the camera, and P1 represents the degree to which each pixel faces the camera.

[0106] In some embodiments, when the degree to which each pixel faces the camera is calculated, the facing coefficient K1 used by each pixel in the wrinkled surface to be rendered can have the same value.

[0107] In other embodiments, when the degree to which each pixel faces the camera is calculated, the facing coefficient K1 used by each pixel in the wrinkled surface to be rendered can also have different values.

[0108] A2, taking the degree to which each pixel faces the camera as a relative position between each pixel and the rendering camera.

[0109] By taking the camera-facing degree of each pixel as the relative position between each pixel and the rendering camera, the camera-facing degree of each pixel can be changed by adjusting the size of the facing coefficient K1, so as to enhance or weaken the visual angle between each pixel and the rendering camera, and finally act on the basic color of each pixel in combination with step 1032A, so as to improve the richness of the rendered wrinkle surface. Therefore, based on the camera-facing degree of each pixel as the relative position between each pixel and the rendering camera, the richness of the wrinkle surface to be rendered can be improved at the level of the visual angle of the pixel facing the camera.

[0110] ②Taking the degree of each pixel facing away from the rendering camera (i.e., the camera-facing degree of each pixel) as the relative position between each pixel and the rendering camera. At this time, step 1031A can specifically include the following steps B1-B2:

[0111] B1, obtaining the camera-facing degree of each pixel by performing dot product on the normal of each pixel and the camera direction vector.

[0112] Wherein, the camera-facing degree of each pixel is used to reflect the degree of each pixel facing away from the rendering camera. By changing the camera-facing degree of each pixel, the visual angle between each pixel and the rendering camera can be enhanced or weakened, and acts on the basic color of each pixel, so as to show the richness of the wrinkle surface.

[0113] Wherein, the dot product of the normal of each pixel and the camera direction vector (denoted as "dot(Normal,CameraVector)") is the dot product of two vectors (normal vector and camera direction vector), which can be used to describe the angle between two directions in graphics rendering. Therefore, (1-dot(Normal,CameraVector)) reflects the degree of each pixel facing away from the rendering camera; multiplying (1-dot(Normal,CameraVector)) by a facing coefficient (denoted as "K2"), the degree of each pixel facing away from the rendering camera can be adjusted by adjusting the size of the facing coefficient K2, so as to show the richness of the wrinkle surface. As shown in the following formula (2), the normal of each pixel and the camera direction vector can be directly calculated to obtain the camera-facing degree of each pixel by substituting them into the preset facing formula. At this time, step B1 can specifically include: calculating the camera-facing degree of each pixel according to the normal of each pixel, the camera direction vector and the preset facing formula. Wherein, the preset facing formula is as follows:

[0114] P2=K2*(1-dot(Normal,CameraVector) Formula (2)

[0115] In formula (2), dot(Normal, CameraVector) represents the dot product of the normal of each pixel and the camera direction vector, K2 is a back coefficient, K2 is used to adjust the back camera degree of each pixel, and P2 represents the back camera degree of each pixel.

[0116] In some embodiments, the same value of the back coefficient K2 can be used for each pixel in the wrinkle surface to be rendered when calculating the back camera degree of each pixel.

[0117] In other embodiments, the back coefficient K2 used by each pixel in the wrinkle surface to be rendered can also take different values when calculating the back camera degree of each pixel.

[0118] B2, taking the back camera degree of each pixel as the relative position between each pixel and the rendering camera.

[0119] By taking the back camera degree of each pixel as the relative position between each pixel and the rendering camera, the back camera degree of each pixel can be changed by adjusting the size of the back coefficient K2 to enhance or weaken the visual angle between each pixel and the rendering camera, and finally acts on the basic color of each pixel in combination with step 1032A, thereby improving the richness of the rendered wrinkle surface. Therefore, determining the relative position between each pixel and the rendering camera based on the back camera degree of each pixel can improve the richness of the wrinkle surface to be rendered at the level of the visual angle of the pixel back camera.

[0120] ③ Based on the degree of each pixel towards the rendering camera and the degree of each pixel away from the rendering camera, determine the relative position between each pixel and the rendering camera. At this time, step 1031A can specifically include the following steps C1-C3:

[0121] C1, obtain the camera degree of each pixel by dot product of the normal of each pixel and the camera direction vector.

[0122] The way of obtaining the camera degree of each pixel in step C1 is similar to the way of obtaining the camera degree of each pixel in step A1 described above, and specific reference can be made to the related description in step A1 described above, which will not be repeated here.

[0123] For example, the normal of each pixel and the camera direction vector can be substituted into the above formula (1) to calculate the camera degree of each pixel.

[0124] C2, obtain the back camera degree of each pixel by dot product of the normal of each pixel and the camera direction vector.

[0125] The back camera degree of each pixel in step C2 is obtained in a similar manner to the back camera degree of each pixel obtained in step B1 described above, and details can be referred to the description of step A1 above, which will not be repeated here.

[0126] For example, the normal vector of each pixel and the camera direction vector can be substituted into formula (2) above to calculate the back camera degree of each pixel.

[0127] C3, determining the relative position between each pixel and the rendering camera according to the camera facing degree of each pixel and the back camera degree of each pixel.

[0128] For example, the camera facing degree of each pixel and the back camera degree of each pixel can be added together as the relative position between each pixel and the rendering camera. For example, the camera facing degree of each pixel, the back camera degree of each pixel can be substituted into formula (3) as follows to calculate the relative position between each pixel and the rendering camera.

[0129] P = P1 + P2 Formula (3)

[0130] In formula (3), P1 represents the camera facing degree of each pixel, P2 represents the back camera degree of each pixel, and P represents the relative position between each pixel and the rendering camera.

[0131] In steps C1-C3, on the one hand, the dot product of the normal of each pixel and the camera direction vector (dot(Normal, CameraVector)) reflects the degree to which each pixel faces the rendering camera; the dot product of the normal of each pixel and the camera direction vector is multiplied by a facing coefficient K1, and by adjusting the size of the facing coefficient K1, the degree to which each pixel faces the rendering camera can be adjusted; thus, based on the degree to which each pixel faces the camera, the relative position between each pixel and the rendering camera is determined, which can improve the richness of the to-be-rendered wrinkled surface in the visual angle of the pixel facing the camera. On the other hand, (1-dot(Normal, CameraVector)) reflects the degree to which each pixel faces away from the rendering camera; (1-dot(Normal, CameraVector)) is multiplied by a facing-away coefficient K2, and by adjusting the size of the facing-away coefficient K2, the degree to which each pixel faces away from the rendering camera can be adjusted; thus, based on the degree to which each pixel faces away from the camera, the relative position between each pixel and the rendering camera is determined, which can improve the richness of the to-be-rendered wrinkled surface in the visual angle of the pixel facing away from the camera. Therefore, by determining the relative position between each pixel and the rendering camera according to the degree to which each pixel faces the camera and the degree to which each pixel faces away from the camera, the richness of the to-be-rendered wrinkled surface can be improved in the visual angles of the pixel facing and facing away from the camera, so that the to-be-rendered wrinkled surface is more richly represented.

[0132] 1032A, multiplying the relative position between each pixel and the rendering camera and the basic color of each pixel to obtain the final rendering color of each pixel.

[0133] According to different determination methods of the relative position between each pixel and the rendering camera, there are various methods for obtaining the final rendering color of each pixel in step 1032A, which exemplarily include:

[0134] 1) The degree to which each pixel faces the rendering camera (i.e., the degree to which each pixel faces the camera) is taken as the relative position between each pixel and the rendering camera. Exemplarily, as shown in the following formula (4), step 1032A can specifically include: multiplying the degree to which each pixel faces the camera and the basic color of each pixel to obtain the final rendering color of each pixel.

[0135] FinalColor = Color*P1 Formula (4)

[0136] In formula (4), FinalColor represents the final rendering color of each pixel, Color represents the basic color of each pixel, and P1 represents the degree to which each pixel faces the camera.

[0137] Since the degree of each pixel facing the camera can improve the richness of the creased surface to be rendered on the level of the visual angle of the pixel facing the camera, by taking the result of multiplying the degree of each pixel facing the camera and the basic color of each pixel as the final rendering color of each pixel, the visual angle of each pixel facing the camera can be effectively applied to the basic color of each pixel, thereby effectively improving the richness of the creased surface.

[0138] 2) Taking the degree of each pixel facing away from the rendering camera (i.e., the degree of each pixel facing away from the camera) as the relative position between each pixel and the rendering camera. Exemplarily, as shown in the following formula (5), step 1032A can specifically include taking the result of multiplying the degree of each pixel facing away from the camera and the basic color of each pixel as the final rendering color of each pixel.

[0139] FinalColor = Color * P2 Formula (5)

[0140] In formula (5), FinalColor represents the final rendering color of each pixel, Color represents the basic color of each pixel, and P2 represents the degree of each pixel facing away from the camera.

[0141] Since the degree of each pixel facing away from the camera can improve the richness of the creased surface to be rendered on the level of the visual angle of the pixel facing away from the camera, by taking the result of multiplying the degree of each pixel facing away from the camera and the basic color of each pixel as the final rendering color of each pixel, the visual angle of each pixel facing away from the camera can be effectively applied to the basic color of each pixel, thereby effectively improving the richness of the creased surface.

[0142] 3) Based on the degree of each pixel facing the rendering camera and the degree of each pixel facing away from the rendering camera, determining the relative position between each pixel and the rendering camera. Exemplarily, as shown in the following formula (6), step 1032A can specifically include taking the result of multiplying the result of adding the degree of each pixel facing the camera and the degree of each pixel facing away from the camera and the basic color of each pixel as the final rendering color of each pixel.

[0143] FinalColor = Color * (P1 + P2) Formula (6)

[0144] In formula (6), FinalColor represents the final rendering color of each pixel, Color represents the basic color of each pixel, P1 represents the degree of each pixel facing the camera, and P2 represents the degree of each pixel facing away from the camera.

[0145] On the one hand, the degree of each pixel facing the camera can improve the richness of the wrinkle surface to be rendered on the level of the visual angle of the pixel facing the camera; on the other hand, the degree of each pixel facing away from the camera can improve the richness of the wrinkle surface to be rendered on the level of the visual angle of the pixel facing away from the camera; therefore, the result obtained by adding the degree of each pixel facing the camera and the degree of each pixel facing away from the camera, and the result of multiplying the basic color of each pixel, as the final rendering color of each pixel, can effectively act the visual angle of each pixel facing the camera on the basic color of each pixel, and effectively act the visual angle of each pixel facing away from the camera on the basic color of each pixel, thereby more comprehensively and effectively improving the richness of the wrinkle surface.

[0146] (ii) substituting the basic color, the normal, and the camera direction vector of each pixel into a preset formula to directly calculate the final rendering color.

[0147] (iv) the preset formula is a formula in which the degree of each pixel facing the rendering camera and the degree of each pixel facing away from the rendering camera finally act on the basic color of each pixel. Illustratively, at this time, step 103 can specifically include the following step 1031B:

[0148] 1031B, according to the normal of each pixel, the camera direction vector, the basic color of each pixel, and the first preset formula, the final rendering color of each pixel is calculated.

[0149] wherein the first preset formula is shown in the following formula (7):

[0150] FinalColor = Color * (K1 * dot(Normal, CameraVector) + K2 * (1-dot(Normal, CameraVector))) formula (7)

[0151] wherein dot(Normal, CameraVector) represents the dot product of the normal of each pixel and the camera direction vector, K1 is a facing coefficient, K2 is an away-from coefficient, K1 is used to adjust the degree of each pixel facing the camera, K2 is used to adjust the degree of each pixel facing away from the camera, Color represents the basic color of each pixel, and FinalColor represents the final rendering color of each pixel.

[0152] Specifically, after the base color of each pixel of the creased surface to be rendered is obtained in step 101 and the normal of each pixel of the creased surface to be rendered is obtained in step 102, in step 1031B, the base color of each pixel of the creased surface to be rendered obtained in step 101, the normal of each pixel of the creased surface to be rendered obtained in step 102, and the camera direction vector of the rendering camera are substituted into the first preset formula, the calculation of the first preset formula is performed, and the calculation result of the first preset formula, i.e., the final rendering color of each pixel, is obtained.

[0153] In step 1031B, in the first aspect, since K1*dot(Normal,CameraVector) reflects the visual angle of each pixel toward the camera and K2*(1-dot(Normal,CameraVector)) reflects the visual angle of each pixel away from the camera, the visual angle of each pixel toward the camera and the visual angle of each pixel away from the camera can be effectively applied to the base color of each pixel through the first preset formula, thereby effectively improving the richness of the creased surface. In the second aspect, by substituting the base color of each pixel of the creased surface to be rendered, the normal of each pixel, and the camera direction vector of the rendering camera into the first preset formula for calculation, the final rendering color of each pixel is obtained. Since one formula calculation is performed, the final rendering color of each pixel can be quickly calculated, and the rendering speed of the creased surface to be rendered can be improved.

[0154] ⑤The preset formula is a formula for finally applying the degree of each pixel toward the rendering camera to the base color of each pixel. Illustratively, at this time, step 103 can specifically include the following step 1031C:

[0155] 1031C, according to the normal of each pixel, the camera direction vector, the base color of each pixel, and the second preset formula, the final rendering color of each pixel is calculated.

[0156] The second preset formula is shown in the following formula (8):

[0157] FinalColor = Color*(K1*dot(Normal,CameraVector)) formula (8)

[0158] Wherein, dot(Normal,CameraVector) represents the dot product of the normal of each pixel and the camera direction vector, K1 is the orientation coefficient, K1 is used to adjust the degree of each pixel toward the camera, Color represents the base color of each pixel, and FinalColor represents the final rendering color of each pixel.

[0159] Specifically, after the base color of each pixel of the creased surface to be rendered is obtained in step 101 and the normal of each pixel of the creased surface to be rendered is obtained in step 102, in step 1031C, the base color of each pixel of the creased surface to be rendered obtained in step 101, the normal of each pixel of the creased surface to be rendered obtained in step 102, and the camera direction vector of the rendering camera are substituted into the second preset formula, the calculation of the second preset formula is performed, and the calculation result of the second preset formula, i.e., the final rendering color of each pixel, is obtained.

[0160] In step 1031C, first, since K1*dot(Normal,CameraVector) reflects the visual angle of each pixel toward the camera, the visual angle of each pixel toward the camera can be effectively applied to the base color of each pixel by the second preset formula, thereby effectively improving the richness of the creased surface. Second, by substituting the base color of each pixel of the creased surface to be rendered, the normal of each pixel, and the camera direction vector of the rendering camera into the second preset formula for calculation, the final rendering color of each pixel is obtained. Since one formula calculation is performed, the final rendering color of each pixel can be quickly calculated, and the rendering speed of the creased surface to be rendered can be improved.

[0161] ⑥The preset formula is a formula for finally applying the degree of each pixel facing away from the rendering camera to the base color of each pixel. Exemplarily, at this time, step 103 can specifically include the following step 1031D:

[0162] 1031D, according to the normal of each pixel, the camera direction vector, the base color of each pixel, and the third preset formula, the final rendering color of each pixel is calculated.

[0163] The third preset formula is shown in the following formula (9):

[0164] FinalColor = Color * (K2 * (1-dot(Normal,CameraVector))) formula (9)

[0165] Wherein, dot(Normal,CameraVector) represents the dot product of the normal of each pixel and the camera direction vector, K2 is a back coefficient, K2 is used to adjust the degree of each pixel facing away from the camera, Color represents the base color of each pixel, and FinalColor represents the final rendering color of each pixel.

[0166] Specifically, after the base color of each pixel of the to-be-rendered wrinkled surface is obtained in step 101 and the normal of each pixel of the to-be-rendered wrinkled surface is obtained in step 102, in step 1031B, the base color of each pixel of the to-be-rendered wrinkled surface obtained in step 101, the normal of each pixel of the to-be-rendered wrinkled surface obtained in step 102, and the camera direction vector of the rendering camera are substituted into a third preset formula, a calculation of the third preset formula is performed, and a result of the calculation of the third preset formula, that is, a final rendering color of each pixel, is obtained.

[0167] In step 1031B, first, since K2*(1-dot(Normal,CameraVector)) reflects the visual angle of each pixel facing away from the camera, the visual angle of each pixel facing away from the camera can be effectively reflected on the base color of each pixel by the third preset formula, so that the richness of the wrinkled surface is effectively improved. Second, by substituting the base color of each pixel of the to-be-rendered wrinkled surface, the normal of each pixel, and the camera direction vector of the rendering camera into the third preset formula for calculation, the final rendering color of each pixel is obtained. Since only one formula calculation is performed, the final rendering color of each pixel can be quickly calculated, and the rendering speed of the to-be-rendered wrinkled surface can be improved.

[0168] 104. rendering the to-be-rendered wrinkled surface according to the final rendering color of each pixel to obtain a final rendering effect of the to-be-rendered wrinkled surface.

[0169] The final rendering color of each pixel is used to improve the display effect of the to-be-rendered wrinkled surface.

[0170] For example, in step 104, during rendering, the final rendering color of each pixel is rendered to the corresponding position of the to-be-rendered wrinkled surface. When the final rendering color of each pixel of the to-be-rendered wrinkled surface is rendered to the corresponding position of the to-be-rendered wrinkled surface, the final rendering effect of the to-be-rendered wrinkled surface is obtained, and is sent to the screen for display. At this time, the final rendering effect of the to-be-rendered wrinkled surface will be enhanced or weakened in the visual angle of each pixel facing toward or away from the camera, so as to improve the richness of the wrinkled surface.

[0171] In order to better understand the graphic rendering method of the embodiment of the present application, the graphic rendering process is described below by taking the to-be-rendered wrinkled surface as a moss surface in a game scene and the rendering camera as a game main camera of the game scene as examples. Please refer to Figure 4 , Figure 4 is an embodiment of the graphic rendering process provided in the embodiment of the present application, and the graphic rendering process can specifically include the following steps 401-405.

[0172] 401. provide a moss surface with a color map, and extract a base color (denoted as Color) of each pixel of the moss surface from the color map of the moss surface.

[0173] wherein the color map of the moss surface is the base color of the moss surface.

[0174] 402. provide a moss surface with a normal map, and extract a normal (denoted as Normal) of each pixel of the moss surface from the normal map of the moss surface.

[0175] 403. obtain a camera direction vector of a game main camera of a game scene.

[0176] 404. substitute the base color of each pixel of the moss surface, the normal of each pixel of the moss surface, and the camera direction vector of the game main camera into a first preset formula, and calculate to obtain a final rendering color of each pixel of the moss surface.

[0177] The implementation of step 404 is similar to the implementation of step 1031B described above, and specific reference can be made to the related description of step 1031B described above. For the sake of simplifying the description, no further description is given here.

[0178] 405. render the moss surface according to the final rendering color of each pixel of the moss surface, and obtain a final rendering effect of the moss surface.

[0179] The implementation of step 405 is similar to the implementation of step 104 described above, and specific reference can be made to the related description of step 104 described above. For the sake of simplifying the description, no further description is given here.

[0180] As can be seen from the above, by obtaining a final rendering color of each pixel of the to-be-rendered wrinkled surface according to a normal of each pixel of the to-be-rendered wrinkled surface, a camera direction vector of a rendering camera of the to-be-rendered wrinkled surface, and a base color of each pixel of the to-be-rendered wrinkled surface, rendering the to-be-rendered wrinkled surface to obtain a final rendering effect of the to-be-rendered wrinkled surface; in the first aspect, since the visual angle between each pixel and the rendering camera can be applied to the base color of each pixel, the visual angle between each pixel and the rendering camera on the to-be-rendered wrinkled surface can be enhanced or weakened by artificially adjusting the visual angle between each pixel and the rendering camera, thereby improving the richness of the wrinkled surface; in the second aspect, since the final rendering effect of the to-be-rendered wrinkled surface is only related to the normal of each pixel and the camera direction vector, and is not related to the light, the inevitable association between the wrinkled effect and the light can be avoided, thereby effectively improving the wrinkled feeling of the wrinkled surface in the absence of light; in the third aspect, since the number of faces of the model does not need to be increased to improve the display effect of the wrinkled surface, the display effect of the wrinkled surface is effectively improved under the condition of reducing the pressure of graphic rendering.

[0181] To better implement the above method, an embodiment of the present application further provides a graphics rendering device, which can be specifically integrated in an electronic device, such as a computer device, which can be a terminal, a server or the like.

[0204] FinalColor = Color * (K1 * dot(Normal, CameraVector) + K2 * (1-dot(Normal, CameraVector)));
