Abstract: We present a practical implementation of a cell projection algorithm for interactive visualization of large volumetric data sets using programmable graphics cards. By taking advantage of the data regularity, we can avoid computing some steps of the original algorithm with no quality loss. Furthermore, performance is increased since more than half the processing time is dedicated only for rendering. We also provide two tools for better user interactivity, one for transfer function editing and another for volume clipping. Our algorithm generates high quality images at a rendering speed of over 5.0 M Tet/s on current graphics hardware.
