Octree-based CRT-buffers manager. This management method has a positive effect on data access in large-scale scene datasets, using the octagonal tree structure to manage the data in the entire scene, divide the scene data, and store the CRT-buffer data (Albedo maps, Direct lighting map, Normal map, Depth map, and Gl map) in the scene to each leaf node, which can effectively improve the system operation efficiency.
