In this chapter, I discuss a fast, hardware-accelerated method for projecting tetrahedra. My algorithm runs efficiently on the current generation of graphics hardware, which is called the DirectX-9 class of graphics cards [61]. Furthermore, I expect the method will be applicable for many generations to come.
I start this chapter by reviewing the cell projection algorithm on which I base my work. I then make improvements on the algorithm that shall significantly improve the rendering speed. Finally, I make extensions to the algorithm that can increase the overall accuracy of the rendering system.
