Method and system for rendering light and shadow dynamics of animation scene

The application provides an animation scene light and shadow dynamic rendering method and system, and relates to the technical field of animation production. First, the light and shadow correlation relationship between each scene element (including scene static structure elements and scene dynamic role elements) in an animation scene is established to obtain a scene element light and shadow correlation graph containing hierarchical division and correlation weight. Based on the scene element light and shadow correlation graph, light and shadow dynamic response rules are generated in combination with atmosphere types. According to the rules, initial light and shadow rendering schemes are generated in combination with current frame scene element state data and atmosphere type identifiers. The interactive influence of the light and shadow effects of each scene element in the initial light and shadow rendering scheme is analyzed. The final light and shadow rendering scheme is generated by adjusting and optimizing the light and shadow parameters through multiple rounds of iteration and is applied to the current frame rendering. Finally, the key light and shadow parameters of the current frame are extracted and analyzed for continuity with the previous frame. Frame-to-frame light and shadow transition parameters are generated for smooth connection of the next frame light and shadow, thereby bringing a smoother and more comfortable visual experience to the audience.
