Rendering method and corresponding apparatus

A rendering apparatus, comprising a processor and a memory;

• the memory stores code, the processor is configured to execute the code, wherein the code, when executed by the processor, instructs the apparatus to:
• obtain an angle of view in which a user browses a target scene;
• for each pixel in a first image, restore a color value of each pixel in each of P directions corresponding to the pixel based on compressed texture information, wherein the first image is a to-be-rendered image that is of the target scene and that corresponds to the angle of view, the P directions corresponding to each pixel are directions in which color values are sampled from a radiance field model of the target scene, P is an integer greater than 1, and the compressed texture information comprises compression information of the color values in the P directions corresponding to each pixel;
• and
• render the first image based on the color value of each pixel in the first image in each of the P directions corresponding to the pixel, to obtain a rendered second image.

A computer program product, comprising computer program code, wherein the computer program code, when run on a computer, instructs the computer to:

• obtain an angle of view in which a user browses a target scene;
• for each pixel in a first image, restore a color value of each pixel in each of P directions corresponding to the pixel based on compressed texture information, wherein the first image is a to-be-rendered image that is of the target scene and that corresponds to the angle of view, the P directions corresponding to each pixel are directions in which color values are sampled from a radiance field model of the target scene, P is an integer greater than 1, and the compressed texture information comprises compression information of the color values in the P directions corresponding to each pixel;
• and
• render the first image based on the color value of each pixel in the first image in each of the P directions corresponding to the pixel, to obtain a rendered second image.
