Boolean operations of 2-manifolds through vertex neighborhood classification
Martti Mäntylä
Pages: 1-29
DOI: 10.1145/7529.7530
A topologically complete set operations algorithm for planar polyhedral Z-manifold objects is described; that is, under the assumption that all numerical tests required can be correctly evaluated, the algorithm is capable of solving all...

An experimental evaluation of computer graphics imagery
Gary W. Meyer, Holly E. Rushmeier, Michael F. Cohen, Donald P. Greenberg, Kenneth E. Torrance
Pages: 30-50
DOI: 10.1145/7529.7920
Accurate simulation of light propagation within an environment and perceptually based imaging techniques are necessary for the creation of realistic images. A physical experiment that verifies the simulation of reflected light intensities for...

Stochastic sampling in computer graphics
Robert L. Cook
Pages: 51-72
DOI: 10.1145/7529.8927
Ray tracing, ray casting, and other forms of point sampling are important techniques in computer graphics, but their usefulness has been undermined by aliasing artifacts. In this paper it is shown that these artifacts are not an inherent part of...
