                         works reported earlier, our methodemploys two fragment shaders,

                         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
