COMPUTER GRAPHICS SEMINAR
- Monday, March 21, 1988
Dr. Ken Musgrave, of Yale University, will speak on
``Ray Tracing Fractal Mountains, with Rainbows''.
TIME: 3:30 PM
ROOM: MC 6091A
ABSTRACT
A model of dispersive refraction for computer graphics
will be presented. This model is an extension of the
distributed ray tracing technique of Rob Cook. An
application of the dispersion model is the simulation
of atmospheric rainbows, which are probably most useful
for placement over simulated landscapes. To that end,
a new and very fast algorithm for ray tracing fractal
mountains created by the triangle subdivision technique
will be discussed. Best of all, some pretty pictures
created for B.B. Mandelbrot at Yale University will be
shown. These images include some novel textures and
atmospheric effects that create convincing
representations of water, clouds and haze.
