A sparse voxel octree (SVO) is a hierarchical octree data structure in which voxels recursively subdivide space into octants, storing only occupied or surface-intersecting regions, making it compact for raycasting and sometimes ray tracing in 3D computer graphics rendering. The technique generally relies on generating and processing the hull of points (sparse voxels) which are visible, or may be visible, given the resolution and size of the screen.
