AbstractWe present a practical approach for implementing theProjected Tetrahedra (PT) algorithm for interactive volumerendering of unstructured data using programmable graphicscards. Unlike similar works reported earlier, our methodemploys two fragment shaders, one for computing the tetrahedraprojections and another for 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 substantially smaller memory footprint.
