An octree is a tree data structure in which each internal node has exactly eight children. Octrees are most often used to partition a three-dimensional...

sparse voxel octree (SVO) is a 3D computer graphics rendering technique using a raycasting or sometimes a ray tracing approach into an octree data representation...

linear octree is an octree that is represented by a linear array instead of a tree data structure. To simplify implementation, a linear octree is usually...
