Theoretical Developments on Polygonal Approximation of Parametric Surfaces for Ray Tracing
(Blackwell Publishing Ltd and the Eurographics Association, 1988)
Some theoretical extensions are brought to Koparkar and Mudur s method which deals with a polygonal approximation of parametric surfaces using potential extrema. The proposed extensions allow the determination of both the ...
A New Algorithm of Space Tracing Using a CSG Model
(Eurographics Association, 1987)
This paper describes a new algorithm of space tracing. Scenes are modeled by a CSG tree. Space is subdivided regularly into 3D regions called boxes. With each box is associated a subtree which is the restriction of the ...
A VLSI Chip for Ray Tracing Bicubic Patches
(Eurographics Association, 1989)
This paper deals with the integration of a VLSI chip dedicated to ray tracing bicubic patches. A recursive subdivision algorithm is embedded in this chip. The recursion stops when the termination conditions are met. A ...
Experimenting with a Parallel Ray-Tracing Algorithm on a Hypercube Machine
(Eurographics Association, 1988)
A parallel space tracing algorithm is presented. It subdivides the scene into regions. These latter are distributed among the processors of an iPSC hypercube machine designed by Intel company. Each processor subdivides its ...
