A Technique for Volumetric CSG based on Morphology

Abstract

In this paper, a new technique for volumetric CSG is presented. The technique requires the input volumes to correspond to solids which fulfill a voxelization suitability criterion. Assume the CSG operation is union. The volumetric union ot two such volumes is defined in terms of the voxelization of the union of the two original solids. The theory behind the new technique is discussed, the algorithm and implementation are presented. Finally, we present images and timings.
