Abstract

When rendering huge point clouds (Euclideon, potree), the impression of a surface can be generated by blending splats with their neighbors. However, without having the surface connectivity, many occluded points are unnecessarily loaded from the octree on disk, generating high latency accesses. By inferring that connectivity from arbitrary levels in an augmented octree, we can avoid loading occluded nodes and unnecessary detail, thus limiting loaded data size to screen resolution.
