Fundamental algorithms for projective voxelization

We develop a voxel-based approach to volume modeling, in which the 3D object is represented as a set of voxels rather than a collection of surfaces. Interpretation with voxel-based representations is an intuitive paradigm, which has been shown to be theoretically sound and possesses enormous computational advantages over modeling with surface-based representations of 3D objects. However, there is no efficient algorithm for volume modeling of graphics primitives. In this paper, we attempt to bridge the gap by an efficient projective voxelization technique suitable for all existing 3D graphics primitives
