September 11, 2001: update to chapter 13
Procedural shading, long valued for off-line rendering and production animation, is just becoming possible on interactive graphics hardware. A wide spectrum of interactive applications are poised to use it -- scientific visualization, product design, game development, and more. This course (formerly titled "Approaches for Procedural Shading on Graphics Hardware") explains the variety of techniques behind shading on current and future graphics hardware. These range from full procedural shading on advanced specialized hardware to limited, yet still surprisingly flexible, shading on unextended OpenGL, to the latest in PC graphics accelerators. Participants will see several of the systems in action and will learn the basic techniques in a series of technology overviews. The course will conclude with a panel session allowing the speakers and audience to discuss the relative merits and pitfalls of the different methods.

Member of Technical Staff
SGI |
Marc Olano is the technical lead and compiler architect for the OpenGL Shader project at SGI. Olano received his Ph.D. in computer science from the University of North Carolina in Chapel Hill under Anselmo Lastra. His dissertation was on a shading language for the PixelFlow graphics system, the first full procedural shading language to run on graphics hardware. In addition to his work on shading algorithms for current and future graphics hardware, he has also done research on shading models, rendering algorithms, model simplification and scientific visualization.
John C. Hart

Associate Professor
Department of Computer Science University of Illinois, Urbana-Champaign |
John C. Hart has worked with Evans & Sutherland on advanced shading techniques for consumer graphics cards, focusing on real-time procedural solid texturing. He received his MS (1989) and Ph.D. (1991) from the EVL at UIC, where he worked on rendering procedurally-generated fractal models on the AT&T Pixel Machine. He currently serves on the SIGGRAPH 2001 Papers Committee and on the editorial board of ACM Transactions on Graphics. Hart served five years on the SIGGRAPH Executive Committee, and as an Executive Producer for the documentary "The Story of Computer Graphics."

Research Associate
Computer Graphics Laboratory Stanford University |
Bill Mark is a research associate in the computer graphics laboratory at Stanford University. He is co-developing a system for real-time programmable shading, and is the project manager for the Stanford Immersive Television project. He received his Ph.D. from the University of North Carolina in May 1999. At UNC he explored the use of image-based rendering techniques to accelerate conventional rendering ("post-rendering warping"). He has also co-developed a software library for force-feedback devices, and taught a one-semester undergraduate course in computer architecture and implementation.

Associate Professor
Department of Computer Science NYU |
Ken Perlin is an Associate Professor in the Department of Computer Science and the director of the Media Research Laboratory at the Courant Institute of Mathematical Sciences of New York University. He is also the director of the NYU Center of Advanced Technology, sponsored by the New York State Science and Technology Foundation. He received his Ph.D. in Computer Science at the Courant Institute and his B.A. in Theoretical Mathematics at Harvard University. In 1991 he was a recipient of a Presidential Young Investigator Award. In 1997 he received a Technical Achievement Award from the Academy of Motion Picture Arts and Sciences for his noise and turbulence procedural texturing techniques, which are widely used in feature films and television.
Dr. Perlin was Head of Software Development at R/GREENBERG Associates in New York, NY from 1984 through 1987. Prior to that, from 1979 to 1984, he was the System Architect for computer generated animation at Mathematical Applications Group, Inc., Elmsford, NY. He has served on the Board of Directors of the New York chapter of ACM/SIGGRAPH.
