Online sculpting and visualization of multi-dexel volumes

Abstract

The idea of multi-dexel volumes is to use more than one dexel volume for representation of a solid. In this manner the difficulty of unequal sampling densities dependent on the slope of the surface relative to the direction of the dexels is overcome. We present algorithms for orthogonal 3-dexel volumes, which concern on-line sculpting by erasing and generating tools and direct rendering. The algorithms achieve computation times better than real time for simulation of milling processes in mechanical engineering.
