Thickness-aware voxelization

Voxelization is a crucial process for many computer graphics applications such as collision detection, rendering of translucent objects, and global illumination. However, in some situations, although the mesh looks good, the voxelization result may be undesirable. In this paper, we describe a novel voxelization method that uses the graphics processing unit for surface voxelization. Our improvements on the voxelization algorithm can address a problem of state-of-the-art voxelization, which cannot deal with thin parts of the mesh object. We improve the quality of voxelization on both normal mediation and surface correction. Furthermore, we investigate our voxelization methods on indirect illumination, showing the improvement on the quality of real-time rendering.
