Abstract
We present the first, view-independent cell projection algorithm for off-the-shelf programmable graphics hardware. Our implementation performs all computations for the projection and scan conversion of a set of tetrahedra on the graphics hardware and is therefore compatible with many of the hardware-accelerated optimizations for polygonal graphics, e.g. OpenGL vertex arrays and display lists. Apart from our actual implementation, we discuss potential improvements on future, more flexible graphics hardware and applications to interactive volume visualization of unstructured meshes.Keywords
