Title:
SCENE RENDERING METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/231215
Kind Code:
A1
Abstract:
The present disclosure provides a scene rendering method and apparatus, an electronic device, and a storage medium. The method comprises: obtaining an environment map; processing the environment map to obtain a first cube map; for a first pixel point in each plane of the first cube map, calculating a target color value of the first pixel point on the basis of a color value of the first pixel point and color values of second pixel points in other planes to obtain a second cube map; on the basis of a first low-discrepancy sequence algorithm, sampling, by means of light in a scene to be rendered, pixel points comprised in the second cube map to obtain a sampling point; determining a maximum brightness value of the pixel points in a brightness sub-area pointed by the light in said scene, and determining the maximum brightness value as a brightness value of the sampling point; and rendering said scene on the basis of the target color value and the maximum brightness value of the sampling point. Therefore, the rendering efficiency can be improved, and it is ensured that the sampling is uniform and random, and the rendering effect picture is real and natural.
