The Pixel-Planes group built a series of image-generation engines, based on the concepts of pixel-parallelism and linear expression evaluation:
* Pixel-Planes 1-4 (1981-1986), which implemented a full-screen pixel parallel array.
* Pixel-Planes 5 (1987-1991), which implemented multiple 128x128 arrays connected by a high-speed ring network.
* PixelFlow (1991-1997), which implemented a parallel rendering system based on real-time depth-based image compositing.
These various architectures also pioneered concepts in programmable shading and antialiasing.
The most recent system, PixelFlow was a linearly scalable architecture--its performance increased linearly with the size of the system. It was based on five high-speed custom chips, and used experimental high-speed, low-voltage signaling technology to composite images at the rates required.
PixelFlow technology was licensed to Hewlett-Packard, Integrated Device Technology, Ivex Corporation, and PixelFusion Ltd. I took part in the development of a full-scale prototype PixelFlow system, done jointly with HP, and demonstrated at Siggraph '97. This system generated over 50 million polygons per second and rendering effects such as bump-mapping, shadows, procedural textures, and particle system smoke.
I'm currently at NVIDIA, working in their (amazing) architecture group, in the Durham, NC NVIDIA office.
I am co-chair of Graphics Hardware 2003, to be held in San Diego July 26-27, 2003. I was co-chair or program chair of the 2001, 1999, and 1997 conferences as well. I served on the SIGGRAPH 1999 papers committee.
