several frames as the camera does a complete rotation around each of the principal
axis for an equal amount of frames. As the animation progresses, we observe that
the Hausdorff distance decreases as the process converges to a full voxelization.
6.6 Limitations
One limitation of our method is that the cleanup phase will only remove invalid
voxels that are visible in any of the current image buffers (camera multiple ren-
der targets and light RSMs). The visible invalid voxels will be removed from the
voxelization the next time they appear in the image buffers. However, the cor-
rectness of the voxelization cannot be guaranteed for existing ...
