[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0050] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] 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, further definition and explanation thereof is not required in subsequent drawings.

[0052] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear to indicate an orientation or position relationship, they are based on the orientation or position relationship shown in the accompanying drawings, or are the orientation or position relationship in which the product of the invention is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0053] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0054] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0055] In shader-based rendering, during the vertex rendering stage, the displacement map is sampled to obtain the vertex offset and applied to the original vertex position to achieve a realistic bump effect or to use another color map to blend with the original map.

[0056] This method of using displacement maps has relatively high requirements on the number of model faces, and mobile devices such as mobile phones have inconsistent support for texture sampling at the vertex stage. The solution of using color maps to mix with original maps has relatively poor performance.

[0057] In view of this, the present embodiment provides a dent effect rendering method, device, electronic device and computer-readable storage medium, which can not only obtain a better rendering effect, but also reduce resource consumption and computing cost, which will be described in detail below.

[0058] Please refer to Figure 1 , Figure 1 An example of the process of the dent effect rendering method provided in this embodiment Figure 1 , the method comprises the following steps:

[0059] Step S101 : determining an impact position according to an impact operation performed on a target object.

[0060] In this embodiment, the target object may be a character, object, or NPC (Non-Player Character) in the game scene. The collision operation may be a skill released by a game player in the game, or a collision operation performed by a user on a target object in a virtual reality scene. The collision position may be determined according to the direction of the collision operation, or according to the direction and intensity of the collision operation. For example, in a game scene, the collision position may be determined according to the direction of the skill released, or according to the direction and intensity level of the skill released.

[0061] Step S102, determining a height map and a color map that match the impact position, wherein the height map represents information about the degree of depression, and the color map represents color information of the target object in a depressed state.

[0062] In this embodiment, due to the different degrees of depression, different height visions are visually presented, and different degrees of depression can be represented by the pixel value of each pixel of the height map, and the pixel value of each pixel of the height map ranges from 0 to 1, 1 represents no depression, and 0 represents the maximum degree of depression. The color map represents the color and texture detail information of the concave surface of the target object, and the color value of each pixel in the color map directly corresponds to the color of the corresponding position on the surface of the 3D model.

[0063] Step S103, rendering a dent effect at the impact position according to the height map and the color map.

[0064] In this embodiment, since the height map can represent information about the degree of the dent, and the color map can represent information such as the texture and color of the dent, rendering based on the height map and the color map can obtain a more realistic dent effect at the impact position.

[0065] The above method provided in this embodiment renders the dent effect at the impact position according to the height map and the color map, thereby avoiding high resource consumption and high cost caused by complex shader calculations, and achieving realistic dent effects at a lower computing cost while controllable resource consumption.

[0066] In an optional implementation, the distance between the impact operation and the target object is different, which will affect the visual effect of the dent on the target object. For example, the closer the distance between the two is, the clearer the color and texture of the dent will be, and vice versa. In order to render a dent effect that matches the distance according to the change in the distance between the impact operation and the target object, and further improve the realism of the dent effect, this embodiment provides a method for determining a height map and a color map that match the impact position:

[0067] First, the interaction distance between the impact position and the virtual camera is calculated;

[0068] In this embodiment, the virtual camera is used to capture and display the perspective of the virtual world. In the game scene, the virtual camera is an object with properties such as position, direction and field of view, which not only determines the content seen by the player, but also affects the immersion and interactive experience of the game.

[0069] In this embodiment, the dent effect seen from the perspective of the game player will be different due to different interaction distances.

[0070] Secondly, determining a target preset map group whose interaction distance is within a corresponding preset distance range from the plurality of preset map groups;

[0071] In this embodiment, LOD (Level Of Detail) can be determined according to the needs of the actual scene. For each LOD level, multiple preset map groups can be pre-stored. Different preset map groups correspond to different preset distance ranges. Each preset map group includes a height map and a color map within the corresponding preset distance range and within the field of view of the virtual camera.

[0072] Finally, the height map and color map in the target preset map group are used as the height map and color map that match the impact position respectively.

[0073] In an optional implementation manner, in order to minimize the amount of calculation, this embodiment is based on Figure 1 , provides a way to render the dent effect at the impact position based on the height map and color map, please refer to Figure 2 , Figure 2 An example of the process of the dent effect rendering method provided in this embodiment Figure 2 , step S103 includes the following sub-steps:

[0074] Sub-step S1031, constructing a target cube with the impact position as the center point and a preset length as the side length;

[0075] In this embodiment, the preset length can be set according to actual needs. For example, the preset length is 1, and the unit of the side length can be set according to the proportional relationship between the actual game scene and the real world.

[0076] Sub-step S1032, determining the model space position of each pixel point in the screen area covered by the target cube in the model space of the target cube according to the preset depth map;

[0077] In this embodiment, the pixel value of each pixel in the preset depth map represents the depth information of the pixel in the image of the scene to be rendered. As an implementation method, the image of the scene to be rendered displayed on the screen can be obtained, and then the depth information can be estimated by a preset depth estimation algorithm, and the preset depth map corresponding to the image can be obtained according to the depth information.

[0078] In this embodiment, in order to render a more realistic three-dimensional effect, it is necessary to convert the two-dimensional pixel position of each pixel point in the screen area covered by the target cube into a three-dimensional model space position in the model space of the target cube.

[0079] Sub-step S1033, determining the sampling position of each pixel point according to the height map and the model space position of each pixel point;

[0080] In this embodiment, different degrees of depression, different angles and different directions of depression will cause the color of the depressed state after the impact to be shifted compared to the color before the impact. The sampling position is used to locate the position of the color corresponding to the model space position when sampling.

[0081] Sub-step S1034, sampling the color information of each pixel from the color map according to the sampling position of each pixel;

[0082] Sub-step S1035 , rendering the color of each pixel at the model space position according to the color information of each pixel, and finally obtaining the dent effect at the impact position.

[0083] In an optional implementation manner, in order to accurately determine the model space position of each pixel point in the model space of the target cube, this embodiment provides an implementation method:

[0084] First, the pixel coordinates of each pixel are normalized to obtain the normalized coordinates of each pixel;

[0085] In this embodiment, the normalized coordinates are NDC (Normalized Device Coordinates, NDC normalized device coordinates) coordinates. NDC is a standardized coordinate system ranging from (-1, -1) to (1, 1), and the origin of the NDC coordinate system is at the center of the screen.

[0086] One normalization implementation method is: obtain the screen pixel size and the pixel position of each pixel in the screen area covered by the target cube; calculate the normalized coordinates of each pixel according to the pixel position of each pixel and the screen pixel size. For any pixel, the normalized coordinates can be calculated using the following formula:

[0087] x_NDC=(x_Screen / width)*2–1

[0088] y_NDC=(y_Screen / height)*2-1

[0089] Where x_Screen and y_Screen are the x and y components of the pixel position of the pixel, and width and height are the width and height of the screen pixel size, respectively.

[0090] Secondly, the depth value of each pixel is obtained from the preset depth map according to the normalized coordinates of each pixel;

[0091] Third, construct the standard spatial position of each pixel in the preset standard space according to the normalized coordinates of each pixel and its depth value;

[0092] In this embodiment, since the normalized coordinates are coordinates in a two-dimensional space, by adding the depth value, three-dimensional coordinates in a three-dimensional preset standard space can be constructed.

[0093] Finally, the model space position of each pixel is calculated according to the standard space position of each pixel and the preset transformation matrix, and the preset transformation matrix represents the mapping relationship between the preset standard space and the model space determined by the target cube.

[0094] In this embodiment, the preset conversion matrix may be an inverse matrix of the MVP matrix, and the MVP matrix is ​​usually obtained by multiplying a model matrix (Model Matrix), a view matrix (View Matrix) and a projection matrix (Projection Matrix).

[0095] In an optional implementation manner, in order to more quickly determine the sampling position of each pixel point, this embodiment provides an implementation method:

[0096] (1) Determine the original sampling position of each pixel point according to the model space position of each pixel point;

[0097] In this embodiment, the model space position includes the X-axis coordinate and the Z-axis coordinate in the model space coordinate system. The model space coordinate system takes the center point of the target cube as the origin and the direction of the collision operation as the Y-axis. This embodiment uses any pixel point to illustrate the method of determining the original sampling position:

[0098] The offset unit is determined according to the side length of the target cube; the X-axis coordinate and the Z-axis coordinate of the pixel point are offset by the determined offset units to obtain the offset X-axis coordinate and the offset Z-axis coordinate of the pixel point; the original sampling position of the pixel point is determined according to the offset X-axis coordinate and the offset Z-axis coordinate of the pixel point.

[0099] In this embodiment, if the side length of the target cube is 1, the offset unit is 0.5, and the offset X-axis coordinate and the offset Z-axis coordinate can be obtained by adding 0.5 to the X-axis coordinate and the Z-axis coordinate, respectively. As an implementation method, the offset X-axis coordinate and the offset Z-axis coordinate can be used as the U coordinate in the U direction and the V coordinate in the V direction in the texture coordinate system. The texture coordinate system usually ranges from (0,0) to (1,1). These coordinates are used to locate specific pixels in the texture image. U direction: represents the horizontal direction of the texture image. V direction: represents the vertical direction of the texture image. The coordinate position determined by the U coordinate and the V coordinate is used as the original sampling position.

[0100] (2) Determine the offset of each pixel based on the model space position and height map of each pixel;

[0101] In this embodiment, the direction vector of the virtual camera can be determined first, the height value of each pixel in the height map can be obtained, and the offset of each pixel can be determined according to the direction vector of the virtual camera and the height value of each pixel.

[0102] It should be noted that in order to more realistically simulate the depression effects corresponding to different impact forces, the force of the impact operation can also be obtained, such as obtaining the different force levels of the skills released by the player. Different force levels correspond to different amplification factors. According to the different force levels, the height values ​​obtained from the height map are amplified according to the corresponding amplification factors, so that the final depression effect matches the force, so that the depression effect can be dynamically adjusted according to the force level, which is more realistic.

[0103] (3) Determine the sampling position of each pixel based on the original sampling position and offset of each pixel.
