GRAPHIC & INTERACTION SEMINAR
GB221, at 3:00 p.m., Tuesday 21 November 1989
Mr. Francois Sillion
Cornell University
"Allowing Interaction with Realistic Synthetic"
This talk will concentrate on some advanced features for lighting
simulation programs, and the competition between realism and interactivity.
A general two-pass method for the calculation of realistic synthetic
pictures is presented, that combines the respective strengths of ray
tracing and radiosity, and allows the simulation of both diffuse and
specular interreflection of light.
Yet improving the realism of computer-generated pictures is not enough,
since most serious applications of computer graphics also require some
level of interaction with the user. Some techniques allowing a short
``response time'' from a lighting simulation software are presented, and a
discussion of the respective application areas of the different lighting
calculation models is proposed.
