GPU Point List Generation through Histogram Pyramids.

Video 2.1: Dicer demo (single pot). 

This footage shows how a teapot model is converted to a point cloud, 
and which intermediate data representations are involved.
The teapot was created using glutTeapot(0.6), centered in a world space cube
of [-1,-1,-1] to [1,1,1]. It was then subdivided using a voxel space of
256x256x256, represented as a tiled 2D volume texture.
