                         rendering the elements.We achieve interactive rates by storing the 
                         model in texturememory and avoiding redundant projections of 
                         implementationsusing vertex shaders. Our algorithm is capable 
                         ofrendering over 2.0 M Tets/s on current graphics hardware,making 
                         it competitive with recent ray-casting approches,while occupying a
