ATI Tessellation demo

ATI tessellation demo showing how the GPU can take a relatively simple triangular mesh and use additional normal/displacement data to generate a more rich, detailed mesh on the fly. Extra tessellation detail is generated dynamically and passes straight through the GPU, requiring no extra video memory for the additional vertex data.
