Global Illumination Using DirectX10.1 • Complex solution to compute global illumination With photon mapping and radiance estimation • High quality global illumination evaluated at run-time using spherical harmonics based lighting 3 rd order SH lighting using FP16 260 instructions per pixel to evaluate Albedo Static lighting Dynamic lights Transparent objects Post-process 22
Performance on ATI Radeon HD 4800 • Staggering polygon count at interactive rates (>20fps) – From 900 polygons -> 6K -> 1.6M at the closest tessellated level of details –Up to 18M triangles per frame at fast interactive rates – 6M-8M triangles on average at 20-25 fps • Full high quality lighting and shadowing solution – Rendering all objects into multiple shadow maps more than doubles polygon count per frame • Rendering and simulating high quality detailed 3K froblins at 22 fps on average 23
