ABSTRACT
Largely orthogonal to this encoding, two main flavors of voxelizations can be distinguished (see Figure 2.1). In a surface voxelization (also called boundary voxelization), the scene is interpreted as consisting solely of surfaces, that is, all closed objects are assumed hollow. Therefore, only voxels overlapped by a surface (like a scene triangle) will be nonempty. By contrast, a solid voxelization treats all objects as solids, and hence, any voxel interior to an object will be set. Note that this basically requires the objects to be closed.
