(English Abstract)
The voxel cone tracing algorithm based on the sparse octree stores indirect lighting attributes in a volume, and efficiently traces the volume for indirect illumination and reflections. However, as the volume resolution becomes higher, the amounts of memory and performance overhead significantly increase for the voxel cone tracing. In this paper, we propose a hybrid octree data structure, where sparse leaf nodes use primitive lists while dense leaf nodes still use voxels, and a hybrid tracing algorithm that adaptively performs the cone tracing and ray tracing. Our real-time solution outperforms the existing voxel cone tracing algorithm for high-quality indirect illumination.
