Abstract
A method and apparatus for recognizing a pixel point, an illumination rendering method and apparatus, an electronic device, and a storage medium, which is used to effectively detect a pixel point located in a shadow region, to improve the quality of lightmap rendering. The method includes: obtaining a lightmap of a target object in a target scene; determining, according to a distance between each adjacent pixel point of a pixel point in the lightmap and the pixel point, a coverage radius corresponding to the pixel point; and determining, by using the pixel point as a starting point, that when a ray emitted along at least one tangential direction of the pixel point intersects an unlighted surface of an object in the target scene and a length of the ray is the same as the coverage radius, the pixel point is located in the shadow region.
