Figure 4 As shown, a VR rendering method provided in an embodiment of the present application is applied to the server 200. The VR rendering method may include steps S401 to S403, and these steps are described in detail below.

[0076] S401 , rendering a static scene of a target virtual space at different moving positions in a moving two-dimensional plane to obtain cubemaps corresponding to the different moving positions.

[0077] In the embodiment of the present application, the target virtual space is a VR virtual space to be rendered, which includes static scenes and moving objects. The moving two-dimensional plane is the two-dimensional plane where the moving object moves when it moves in the target virtual space.

[0078] The mobile terminal 200 determines multiple possible moving positions of the moving object in the moving two-dimensional plane, and then renders the static scene at each moving position to obtain a cube map corresponding to each moving position. The cube map serves as the background for subsequent calculation of the two-dimensional map of the moving object at a certain position (i.e., the subsequent target moving position) and a certain perspective (i.e., the subsequent target perspective).

[0079] In one possible implementation, the moving two-dimensional plane can be divided into multiple grid areas, and then the static scene is rendered under each grid area to obtain the texture cube map and depth cube map corresponding to each grid area. Figure 5 , Figure 5 This is a partial flow chart of a VR rendering method provided in an embodiment of the present application. Figure 5 As shown, an embodiment of the present application provides a VR rendering method, wherein step S401 "renders a static scene of a target virtual space at different moving positions in a moving two-dimensional plane to obtain cube maps corresponding to different moving positions" may include steps S4011 to S4014, and these steps are described in detail below.

[0080] S4011, dividing the moving two-dimensional plane into a plurality of grid areas.

[0081] In the embodiment of the present application, the size of a single grid area can be determined according to the positioning accuracy of the target virtual space. , assuming that the moving two-dimensional plane The minimum value of the direction is 0 and the maximum value is , continue to assume that the moving two-dimensional plane The minimum value of the direction is 0 and the maximum value is , then the size of a single grid area is By dividing the moving two-dimensional plane, we can obtain Directional grid area, Directional grid area, you can define The direction of indivual, The direction of The grid area is ,in The value range is 、 The value range is .

[0082] S4012, rendering a texture cube map of each grid area in a static scene at a preset height, where the texture cube map covers a 360° viewing angle.

[0083] In this embodiment, the height of the virtual camera when rendering a static scene is set to a preset height. For each grid area in the moving two-dimensional plane, the virtual camera is placed at the center of the grid area at the preset height, and the texture cubemap corresponding to the grid area is obtained using engine rendering. The texture cubemap covers a 360-degree viewing angle.

[0084] S4013 , during the rendering process of the texture cube map of each grid area, obtaining the depth value of each grid area and writing it into the image to synthesize the depth cube map of each grid area.

[0085] In an embodiment of the present application, for each grid area in the moving two-dimensional plane, during the rendering process of the texture cube map corresponding to the grid area, the depth value of the depth buffer can be synchronously written into the image to synthesize the depth cube map.

[0086] S4014: Establish a mapping relationship between each grid area and its texture cube map and depth cube map.

[0087] In the embodiment of the present application, for each grid area in the moving two-dimensional plane, a mapping relationship is established between the grid area and its corresponding texture cube map and depth cube map. Specifically, the mapping relationship can be expressed as ,in, Represented as a grid area the corresponding texture cubemap, Represented as a grid area The corresponding depth cubemap.

[0088] Subsequently, based on the above mapping relationship, the texture cube map and depth cube map corresponding to the specified grid area can be indexed.

[0089] In one possible implementation, the texture cubemap and depth cubemap corresponding to each grid area may be compressed and stored to reduce the storage resource usage of the server 200. In this regard, an embodiment of the present application provides a VR rendering method, wherein step S401 of "rendering a static scene in a target virtual space at different moving positions in a moving two-dimensional plane to obtain cubemaps corresponding to different moving positions" may further include the following steps:

[0090] Based on the mapping relationship, the texture cube map and depth cube map corresponding to each grid area are compressed and stored.

[0091] In an embodiment of the present application, based on the above mapping relationship, the texture cube map and depth cube map corresponding to each grid area can be compressed using ASTC or H.265 compression and stored in a storage system.

[0092] S402, receiving a rendering request sent by the VR terminal, where the rendering request includes a target moving position and a target viewing angle of a moving object in a target virtual space in a moving two-dimensional plane when the moving object is rendered by the VR terminal, and a rendering result of the moving object by the VR terminal includes a first two-dimensional map.

[0093] In the embodiment of the present application, during the user usage phase, the VR terminal 100 initializes the dynamic scene configuration (including configuration of the virtual FOV resolution, etc.) and synchronizes the virtual and real positions and perspectives (i.e., the orientation of the VR glasses) within the positioning solution. The VR terminal obtains the rendering result of the moving object in the current frame through front-end real-time rendering. The rendering result includes a two-dimensional map (i.e., a first two-dimensional map). The VR terminal then places the position (i.e., the target moving position) and perspective (i.e., the target perspective) of the moving object in the current frame in the moving two-dimensional plane in a rendering request, which is sent to the server 200.

[0094] In this regard, after receiving the rendering request sent by the VR terminal 100, the server 200 can parse it to obtain the target moving position and target viewing angle corresponding to the current frame.

[0095] S403 , determining a target cubemap corresponding to the target moving position, and calculating a second two-dimensional map of the target cubemap under the target viewing angle.

[0096] In the embodiment of the present application, the server 200 obtains cubemaps at different moving positions in advance, and can determine the target cubemap corresponding to the target moving position therefrom, and synchronize the target perspective to the virtual camera. By overlaying the target cubemap on the inner surface of a spherical mesh, a rendering background layer is generated, and a three-dimensional rendering process (which can use the currently mature transformation and rasterization calculation process) is used to calculate the two-dimensional texture (i.e., the second two-dimensional texture) of the rendering background layer recorded by the virtual camera.

[0097] In a possible implementation, when the moving two-dimensional plane is divided into a plurality of grid areas, the "determining the target cubemap corresponding to the target moving position" in step S403 may be performed as follows:

[0098] A target grid area where the target movement position is located is determined, and a target texture cube map and a target depth cube map corresponding to the target grid area are determined based on the mapping relationship.

[0099] In the embodiment of the present application, according to the size of a single grid area The grid area where the target moving position is located (i.e., the target grid area) can be calculated, and then the texture cube map (i.e., the target texture cube map) and the depth cube map (i.e., the target depth cube map) corresponding to the target grid area can be determined based on the above mapping relationship.

[0100] S404: Send the second two-dimensional texture to the VR terminal, so that the VR terminal synthesizes the screen content according to the first two-dimensional texture and the second two-dimensional texture.

[0101] In an embodiment of the present application, after obtaining the second two-dimensional map, the server 200 can send the second two-dimensional map to the VR terminal 100, and the VR terminal 100 synthesizes the first two-dimensional map and the second two-dimensional map to obtain the picture content of the current frame.

[0102] In a possible implementation, the rendering result of the current frame rendered by the VR terminal 100 includes a texture map (i.e., a first texture map), a depth map (i.e., a first depth map), and a transparency map. The first texture map records the texture value of each pixel when the moving object is rendered; the first depth map records the depth value of each pixel when the moving object is rendered; the transparency map records the transparency value of each pixel when the moving object is rendered, and the transparency value range is When the transparency value is 1, it means it is not transparent, and when the transparency value is 0, it means it is fully transparent.

[0103] The cubemap includes a texture cubemap and a depth cubemap, and the target cubemap corresponding to the target moving position includes a target texture cubemap and a target depth cubemap. The server 200 can sequentially use the target texture cubemap and the target depth cubemap as rendering background layers, thereby obtaining a second two-dimensional map including a second texture map and a second depth map. The second texture map records the texture value of each pixel in the static scene at the target moving position and the target viewing angle; the second depth map records the depth value of each pixel in the static scene at the target moving position and the target viewing angle.

[0104] In this regard, an embodiment of the present application provides a VR rendering method, wherein in step S403, "calculating a second two-dimensional map of the target cube map at the target perspective" can be performed using the following steps:

[0105] A first rendering background layer is generated by overlaying the target texture cube map onto the inner surface of the first spherical mesh, and a second texture map of the first rendering background layer at the target perspective is calculated. A second rendering background layer is generated by overlaying the target depth cube map onto the inner surface of the second spherical mesh, and a second depth map of the second rendering background layer at the target perspective is calculated.

[0106] In an embodiment of the present application, after obtaining a target texture cubemap and a target depth cubemap, the target perspective is synchronized with the virtual camera. On the one hand, a rendering background layer (i.e., a first rendering background layer) is generated by overlaying the target texture cubemap onto the inner surface of a spherical mesh (i.e., a first spherical mesh), and a 3D rendering process is used to calculate the texture map (i.e., a second texture map) of the first rendering background layer as recorded by the virtual camera. On the other hand, a rendering background layer (i.e., a second rendering background layer) is generated by overlaying the target depth cubemap onto the inner surface of a spherical mesh (i.e., a second spherical mesh), and a 3D rendering process is used to calculate the depth map (i.e., a second depth map) of the second rendering background layer as recorded by the virtual camera.

[0107] Accordingly, step S404 of "sending the second two-dimensional texture to the VR terminal so that the VR terminal synthesizes the screen content according to the first two-dimensional texture and the second two-dimensional texture" can be performed using the following steps:

[0108] The second texture map and the second depth map are sent to the VR terminal to achieve:

[0109] The VR terminal determines the opaque area and the transparent area based on the transparency map; for each pixel in the opaque area, determines the first depth value of the pixel in the first depth map and the second depth value of the pixel in the second depth map; if the first depth value is less than the second depth value, determines the first texture value of the pixel in the first texture map and outputs it for display; if the first depth value is greater than or equal to the second depth value, determines the second texture value of the pixel in the second texture map and outputs it for display; for each pixel in the transparent area, determines the third texture value of the pixel in the first texture map and the fourth texture value in the second texture map; determines the transparency value of the pixel in the transparency map; calculates the actual texture value of the pixel based on the transparency value, the third texture value and the fourth texture value, and outputs it for display.

[0110] In the embodiment of the present application, the server 200 can compress and transmit the second texture map and the second depth map to the VR terminal 100, and the VR terminal 100 can obtain the second texture map and the second depth map after decompression.

[0111] During the process of synthesizing the picture content of the current frame, the VR terminal 100 first determines the impermeable area and the transparent area based on the transparency map, wherein the transparency value of the pixel points in the impermeable area is greater than the transparency value of the pixel points in the transparent area. For example, the transparency value of the pixel points in the impermeable area is 1, and the transparency value of the pixel points in the transparent area is less than 1.

[0112] For each pixel in the impermeable area, determine the depth value of the pixel in the first depth map (i.e., the first depth value) and the depth value of the pixel in the second depth map (i.e., the second depth value), and compare the first depth value with the second depth value; if the first depth value is less than the second depth value, it means that the moving object is closer to the VR glasses. At this time, the texture value of the pixel in the first texture map (i.e., the first texture value) is determined, and the first texture value is output and displayed; if the first depth value is greater than or equal to the second depth value, it means that the static scene is closer to the VR glasses (i.e., the moving object is blocked by the static scene). At this time, the second texture value of the pixel in the second texture map is determined, and the second texture value is output and displayed.

[0113] For each pixel in the transparent area, the texture value of the pixel in the first texture map (i.e., the third texture value) and the texture value of the pixel in the second texture map (i.e., the fourth texture value) can be determined, and then the transparency value of the pixel in the transparency map can be determined. The actual texture value of the pixel is calculated based on the transparency value, the third texture value, and the fourth texture value, and the actual texture value is output and displayed. Specifically, assuming that the third texture value corresponding to the pixel is , the fourth texture value is , transparent value is , then the actual texture value of the pixel is .

[0114] Based on this, the texture value of each pixel in the current frame can be output to form the picture content.

[0115] As described above, the VR rendering method provided in the embodiment of the present application is different from traditional full-scene real-time rendering or perspective-by-perspective pre-rendering. Through two-dimensional grid sampling and cube map mapping, only fewer rendering resources are required to support a continuous immersive experience of large-space perspective rotation, occupying fewer server resources and ensuring rendering effects, especially reducing the VR rendering cost of large spaces.
