Abstract :
We present a new approach for voxelization of implicit solids which contain sharp details. If such objects are processed by common techniques, voxelization artifacts may appear, resulting, among others, in jaggy edges in rendered images. To cope with this problem we proposed a technique called sharp details correction. The main idea is to modify objects during the process of voxelization according to the representability criterion. This means that sharp edges end vertices are rounded to a curvature, which depends on the grid resolution. Thus, we obtain artifact-free voxelized solids which produce alias-free images.
