DEPARTMENT OF COMPUTER SCIENCE
UNIVERSITY OF WATERLOO
COMPUTER SCIENCE COLLOQUIUM - Wednesday, November 3, 1982.
Mr. Al Paeth of Xerox Palo Alto Research Center will
speak on "PIXELPLANES - Adding a New Dimension to
VLSI-based Computer Graphics".
TIME: 7:00 PM (Please Note)
ROOM: M&C 5158
ABSTRACT
This talk describes Pixelplanes, a high-performance,
VLSI-based graphics system, designed and implemented
at the PARC/VLSI Systems Design Area in collaboration
with the University of North Carolina at Chapel Hill.
Pixelplanes employs algorithms which are a departure
from traditional rendering methods, but are nonethe-
less quite amenable to wafer-scale hardware implemen-
tations. Our device hardware supports one unifying
algorithm, which in turn provides area filling, hid-
den surface elimination, viewport clipping and color
shading, with running time proportional to scene com-
plexity and independent of image size.
The talk will give an overview of some traditional
problems of 3D scene rendering, discuss the Pixel-
plane architecture and software in detail, and con-
clude with a discussion of the implications of the
existence of such a system.
Coffee and refreshments will be served at 6:30 PM.
