Description

Technical Field

[0001] The present application relates to the field of image processing technology, and in particular to a rendering method, device, electronic device and computer-readable storage medium. Background Art

[0002] In modern rendering engines, except for mobile platforms and VR platforms, most rendering pipelines use deferred rendering. First, the relevant information of the rendered object is cached in a global buffer. Then, the content stored in the buffer and the lights in the scene are used for lighting calculations to finally generate the entire picture to be rendered. However, in existing technologies, pixel rendering information occupies too much memory, which reduces the efficiency of deferred rendering. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a rendering method, device, electronic device and computer-readable storage medium, which can effectively reduce the memory occupied by pixel rendering information, thereby improving the efficiency of delayed rendering.

[0004] The present application embodiment provides a rendering method, including:

[0005] Get pixel rendering information;

[0006] Get the parity of the pixel coordinates;

[0007] compressing and storing the pixel rendering information according to the parity of the pixel coordinates;

[0008] Delayed rendering is performed according to the compressed and stored pixel rendering information.

[0009] In the above implementation process, different from the prior art, the pixel rendering information is stored according to the parity of the pixel coordinates, and the adjacent pixel rendering information in the picture has similarity. The pixel rendering information is compressed and stored according to the parity of the pixel coordinates, which can effectively reduce the memory occupied by the pixel rendering information, reduce the bandwidth occupied by calling the pixel rendering information during the rendering process, and improve the rendering efficiency.

[0010] Further, the pixel rendering information includes: color information;

[0011] After the step of obtaining pixel rendering information, the method further includes:

[0012] Converting the color information based on a brightness color model;

[0013] The step of compressing and storing the pixel rendering information according to the parity of the pixel coordinates comprises:

[0014] The converted color information is compressed and stored according to the parity of the pixel coordinates.

[0015] In the above implementation process, brightness is high-frequency information and is an important factor in ensuring the quality of the rendered image. Therefore, converting the color information based on the brightness color model can preserve the brightness information to the greatest extent in the converted color information, so that the rendering quality is still maintained after the converted color information is subsequently compressed and stored.

[0016] Furthermore, the pixel rendering information also includes: normal information;

[0017] After the step of obtaining pixel rendering information, the method further includes:

[0018] compressing the normal information;

[0019] The step of compressing and storing the pixel rendering information according to the parity of the pixel coordinates comprises:

[0020] The compressed normal information is compressed and stored according to the parity of the pixel coordinates.

[0021] In the above implementation process, the pixel rendering information includes normal information, and the normal information is compressed after the pixel rendering information is obtained, so that the memory occupied by the pixel rendering information is further reduced, thereby improving the delayed rendering efficiency.

[0022] Furthermore, the step of converting the color information based on the brightness color model includes:

[0023] The coordinates of the color information are converted into coordinates corresponding to the Y'CbCr model.

[0024] In the above implementation process, the Y'CbCr brightness color model can extract the brightness information from the color information. Based on the above implementation, the rendering efficiency can be improved while ensuring the rendering quality.

[0025] Furthermore, the step of compressing the normal information comprises:

[0026] Construct an octahedral coordinate system;

[0027] The coordinate information in the normal information is converted into plane coordinates corresponding to the octahedral coordinate system.

[0028] In the above implementation process, a method for compressing normal information is proposed. Compared with the method of using a spherical coordinate system to represent normal information in the prior art, the use of an octahedral coordinate system can reduce the amount of calculation and the storage space of normal information, thereby improving rendering efficiency.

[0029] Further, the pixel rendering information is stored in a geometry storage area, and the geometry storage area includes: a first geometry storage area;

[0030] The step of compressing and storing the converted color information according to the parity of the pixel coordinates comprises:

[0031] When the parity of the horizontal coordinate and the vertical coordinate of the pixel coordinate is the same, storing the Y'Cb component in the converted color information in the first geometric storage area;

[0032] When the parities of the horizontal coordinate and the vertical coordinate of the pixel coordinate are different, the Y'Cr component in the converted color information is stored in the first geometry storage area.

[0033] In the above implementation process, each pixel will store different pixel rendering information from the pixels adjacent to the cross. However, each pixel will store brightness information. Since brightness information is high-frequency information, if it is restored using surrounding pixels, the error will be relatively large. If each pixel stores brightness information, the entire picture can be restored well.

[0034] Further, the pixel rendering information is stored in a geometry storage area, and the geometry storage area includes: a second geometry storage area and a third geometry storage area;

[0035] The step of compressing and storing the compressed normal information according to the parity of the pixel coordinates comprises:

[0036] When the parities of the horizontal coordinate and the vertical coordinate of the pixel coordinate are different, the horizontal coordinate of the compressed normal information is stored in the second geometric storage area, and the vertical coordinate of the compressed normal information is stored in the third geometric storage area.

[0037] In the above implementation process, each pixel stores different normal information from the pixels adjacent to the cross. Since the pixel rendering information corresponding to the pixels adjacent to the cross is similar, if the geometric storage area corresponding to the current pixel does not have normal information, it can be obtained through the normal information corresponding to the pixels adjacent to the cross.

[0038] Further, the pixel rendering information includes: metalness information and roughness information;

[0039] The pixel rendering information is stored in a geometry storage area, and the geometry storage area includes: a second geometry storage area and a third geometry storage area;

[0040] The step of compressing and storing the pixel rendering information according to the parity of the pixel coordinates comprises:

[0041] When the parity of the horizontal coordinate and the vertical coordinate of the pixel coordinate is the same, the roughness information is stored in the second geometry storage area, and the metalness information is stored in the third geometry storage area.

[0042] In the above implementation process, each pixel stores different metallicity information and roughness information with respect to the pixels adjacent to the cross. Since the pixel rendering information corresponding to the pixels adjacent to the cross is similar, if the geometric storage area corresponding to the current pixel does not have metallicity information and roughness information, it can be obtained through the metallicity information and roughness information corresponding to the pixels adjacent to the cross.

[0043] In a second aspect, an embodiment of the present application provides a rendering device, including:

[0044] A rendering information acquisition module, used to acquire pixel rendering information, wherein the pixel rendering information includes: color information;

[0045] A pixel coordinate acquisition module, used to obtain the parity of pixel coordinates;

[0046] A compression storage module, used for compressing and storing the pixel rendering information according to the parity of the pixel coordinates;

[0047] The delayed rendering module is used to perform delayed rendering according to the compressed and stored pixel rendering information.

[0048] In the above implementation process, different from the prior art, the pixel rendering information is stored according to the parity of the pixel coordinates, and the adjacent pixel rendering information in the picture has similarity. The pixel rendering information is compressed and stored according to the parity of the pixel coordinates, which can effectively reduce the memory occupied by the pixel rendering information, reduce the bandwidth occupied by calling the pixel rendering information during the rendering process, and improve the rendering efficiency.

[0049] In a third aspect, an embodiment of the present application provides an electronic device, comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the method described in any one of the first aspects when executing the computer program.

[0056] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0057] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0058] Example 1

[0059] See also Figure 1 , an embodiment of the present application provides a rendering method, comprising:

[0060] S1: Get pixel rendering information;

[0061] S2: Get the parity of the pixel coordinates;

[0062] The parity of pixel coordinates refers to the parity of the horizontal and vertical coordinates of the pixel coordinates.

[0063] S3: compress and store pixel rendering information according to the parity of pixel coordinates;

[0064] In the prior art, each pixel coordinate has its corresponding pixel rendering information, and compressed storage refers to the parity of the values ​​of the horizontal coordinate and the vertical coordinate of the pixel coordinate.

[0065] S4: Perform delayed rendering according to the compressed and stored pixel rendering information.

[0066] In the above embodiment, different from the prior art, the pixel rendering information is stored according to the parity of the pixel coordinates, and the adjacent pixel rendering information in the picture has similarity. The pixel rendering information is compressed and stored according to the parity of the pixel coordinates, which can effectively reduce the memory occupied by the pixel rendering information, reduce the bandwidth occupied by calling the pixel rendering information during the rendering process, and improve the rendering efficiency.

[0067] In a possible implementation, the rendering information includes: color information;

[0068] After step S1, it also includes:

[0069] Convert color information based on brightness color model;

[0070] S3 includes: compressing and storing the converted color information according to the parity of the pixel coordinates.

[0071] In the above implementation process, brightness is high-frequency information and is an important factor in ensuring the quality of the rendered image. Therefore, converting the color information based on the brightness color model can preserve the brightness information to the greatest extent in the converted color information, so that the rendering quality is still maintained after the converted color information is subsequently compressed and stored.

[0072] The embodiment of the present application provides a method for converting color information based on a brightness color model, including:

[0073] Convert the color information coordinates to the coordinates corresponding to the Y'CbCr model.

[0074] In a possible implementation, the Y'UV color model may also be used to represent color information.

[0075] In the above implementation process, the existing technology uses the RGB color model to represent color information, while the Y'CbCr brightness color model can extract brightness information from color information. Based on the above implementation, the rendering efficiency can be improved while ensuring the rendering quality.

[0076] Pixel rendering information is usually stored in the geometry storage area. The rendering process completes deferred rendering by calling the pixel rendering information in the geometry storage area (G-Buffer). The collection storage area usually includes the first geometry storage area (GBuffer.RG), the second geometry storage area (GBuffer.B) and the third geometry storage area (GBuffer.A).

[0077] Based on the method of using the Y'CbCr model to represent color information, the embodiment of the present application also provides a method for compressing and storing the converted color information, including:

[0078] When the parity of the horizontal coordinate and the vertical coordinate of the pixel coordinate is the same, the Y'Cb component in the converted color information is stored in the first geometric storage area;

[0079] When the parities of the horizontal coordinate and the vertical coordinate of the pixel coordinate are different, the Y'Cr component in the converted color information is stored in the first geometry storage area.

[0080] Wherein, Y' represents brightness information.

[0081] In the above implementation process, each pixel will store different pixel rendering information from the pixels adjacent to the cross. However, each pixel will store brightness information. Since brightness information is high-frequency information, if it is restored using surrounding pixels, the error will be relatively large. If each pixel stores brightness information, the entire picture can be restored well.

[0082] In a possible implementation, the pixel rendering information further includes: normal information;

[0083] After step S1, the process further includes: compressing normal information;

[0084] S3 includes: storing the compressed normal information according to the parity of the pixel coordinates.

[0085] In the above implementation process, the pixel rendering information includes normal information, and the normal information is compressed after the pixel rendering information is obtained, so that the memory occupied by the pixel rendering information is further reduced, thereby improving the delayed rendering efficiency.

[0086] In the prior art, a spherical coordinate system is usually used to represent normal information. Using coordinates corresponding to the spherical coordinate system to represent normal information requires 24 bits. Based on this, the present application proposes a method for compressing normal information, which includes:

[0087] Construct an octahedral coordinate system;

[0088] Exemplarily, the expression corresponding to the octahedron is |X|+|Y|+|Z|=1

[0089] The coordinate information in the normal information is converted into the plane coordinates corresponding to the octahedral coordinate system.

[0090] In the above embodiment, the coordinates in the plane coordinate system occupy 16 bits, and each coordinate occupies 8 bits.

[0091] In the above embodiment, a method for compressing normal information is proposed. Compared with the method of using a spherical coordinate system to represent normal information in the prior art, using an octahedral coordinate system can reduce the amount of calculation and the storage space of normal information, thereby improving rendering efficiency.

[0092] Based on the above-mentioned normal information compression method, the embodiment of the present application proposes a method for compressing and storing compressed normal information, including:

[0093] When the parities of the abscissa and the ordinate of the pixel coordinates are different, the abscissa of the compressed normal information is stored in the second geometry storage area, and the ordinate of the compressed normal information is stored in the third geometry storage area.

[0094] In the above embodiment, each pixel stores different normal information from the pixels adjacent to the cross. Since the pixel rendering information corresponding to the pixels adjacent to the cross is similar, if the geometric storage area corresponding to the current pixel has no normal information, it can be obtained through the normal information corresponding to the pixels adjacent to the cross.

[0095] In a possible implementation, the pixel rendering information includes: metalness information and roughness information;

[0096] Based on this, S3 includes: when the parity of the horizontal coordinate and the vertical coordinate of the pixel coordinate is the same, storing the roughness information in the second geometric storage area and storing the metalness information in the third geometric storage area.

[0097] In the above embodiment, each pixel stores different metallicity information and roughness information from the pixels adjacent to the cross. Since the pixel rendering information corresponding to the pixels adjacent to the cross is similar, if the geometric storage area corresponding to the current pixel does not have metallicity information and roughness information, it can be obtained through the metallicity information and roughness information corresponding to the pixels adjacent to the cross.
