This talk compares the procedural shaders used in feature animation such as the Perlin Noise function, brick and fur shaders, and their real-time counterparts, explaining the tradeoffs required to bring them to real time. The attendees learn how movie shaders and real-time shaders differ, the trade-offs that must be made for writing real-time shaders, and which shader techniques are transferrable from the movie domain and which are not.|
