We propose an indirect empty volume representation that encodes void octree cells on a regular scalar grid. Our unbounding volume hierarchy is either applied as a standalone acceleration structure for ray marching implicitly defined volumes or to augment sampled implicit function value grids as an additional scalar per voxel. Empty regions are iden...

Difference hierarchies were originally introduced by Hausdorff and they play an important role in descriptive set theory. In this survey paper, we study difference hierarchies of regular languages. The first sections describe standard techniques on difference hierarchies, mostly due to Hausdorff. We illustrate these techniques by giving decidabilit...
