1. An illumination rendering method, performed by a computing device, comprising:
determining a current scene shading point;
emitting, according to the current scene shading point, a virtual marching ray;
determining, according to scene signed-distance-field information corresponding to a current frame, a marching length corresponding to the virtual marching ray;
determining at least one scene intersection point by controlling the virtual marching ray to extend into a scene, wherein the virtual marching ray is controlled to extend into the scene according to the marching length; and
determining, according to incident light information and material information of the scene intersection point, color information of the scene intersection point, wherein the color information is used for indirect illumination calculation.
