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 of 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." }
