- Ikedo T. and Obuchi E., "A Realtime Rough Surface
Renderer" in Proceedings of the Computer Graphics International
Conference CGI2001, IEEE Computer Society Press, April 2001.
Abstract - A realtime
hardware renderer for light-reflected images with rough
surface properties has been developed as one of the graphics
functions embedded within a single chip. The renderer
comprises Phong and Cook/Torrance models on the basis
of empirical, physical or wave theory. To simplify hardware
architecture and avoid vector-normalization, every polygon
interpolation, surface normal, light-source direction,
view direction and bump normal is represented by angular
form. The renderer manipulates multiple light-source reflections
in directional, spot, and light-attenuation, producing
reflective images of rough surfaces within 0.8ns (1.25
billions pixels). The paper describes the new hardware-based
algorithms and architectures.

Abstract - Parims.org
has operating through host universities since 1994 for
R&D of multimedia engines, focusing on hardware architectures
especially for graphics processors. This website shows
various hardware oriented algorithms and architectures
for realtime graphics based upon empirical or physical
models. To generate a realtime virtual reality scene,
fine-grained hardware processing is indispensable. This
can be realized only by discovery of hardware algorithms
and their implementations, without reliance upon fake
technologies such as texture mapping. The site provides
engineers with the most recent and edged technologies
of graphics engine and renderer.
