OpenGL is set up to do texture maps. Our approach does true shear warp volume rendering. OpenGL does not have all the primitives or flexibility to handle this quality of volume visualization. For example, OpenGL can not handle per-sample gradient estimation or per-sample Phong lighting. There are many useful features of the board for which there is no easy mapping from OpenGL.
