1. A method, comprising:
identifying a set of parameters for one or more virtual objects in a 3D scene of a video;
determining a spatial boundary of an intermediate structure for each of the one or more virtual objects in the 3D scene based on a respective object type and a respective object importance weight parameter;
determining an illumination contribution for each plane of the spatial boundary of the intermediate structure for each of the one or more virtual objects in the 3D scene; and
generating the 3D scene of the video based on the determined spatial boundary and the determined illumination contribution for each plane of the spatial boundary of the intermediate structure for each of the one or more objects in the 3D scene.
