Correction of Voxelization Artifacts by Revoxelization
Earlier proposed antialiasing techniques for voxelization of geometric objects in some cases do not result in completely alias-free data and image renditions. This is often the case for some implicit solids and CSG trees. In this paper we propose a set of operations, which can correct such corrupted data sets and subsequently lead to alias-free image renditions.
