Hardware accelerated voxelization

This paper presents a hardware accelerated approach to the voxelization of a wide range of 3D objects, including curves/surfaces, solids, and geometric and volumetric CSG models. The algorithms generate slices of the object models using a surface graphics processor to form the nal volume representations. Boolean operations in a volumetric CSG model are carried out using frame bu er blending functions. By storing the resulting volume in the 3D texture memory, the algorithms can also volume render the models in real time by 3D texture mapping. As a result, we are able to perform interactive object manipulations and Boolean operations in an intermixed environment of geometric and volumetric objects under a uni ed volume graphics framework.
