Alain Fournier, 1943-2000

An Appreciation

There are thinkers of great repute and intellect who would suggest that any objective measure of humankind is in fact a mismeasure. While I am not of a mood to argue the general point either...

Theory and application of specular path perturbation
Min Chen, James Arvo
Pages: 246-278
DOI: 10.1145/380666.380670
In this paper we apply perturbation methods to the problem of computing specular reflections in curved surfaces. The key idea is to generate families of closely related optical paths by expanding a given path into a high-dimensional Taylor...

A variational method to model G1 surfaces over triangular meshes of arbitrary topology in R3
Ramon F. Sarraga
Pages: 279-301
DOI: 10.1145/380666.380674
This article presents a method for constructing a G1-smooth surface, composed of independently parametrized triangular polynomial Bézier patches, to fit scattered data points triangulated in...

Texture-based visibility for efficient lighting simulation
Cyril Soler, F. X. Sillion
Pages: 302-342
DOI: 10.1145/380666.380679
Lighting simulations using hierarchical radiosity with clustering can be very slow when the computation of fine and artifact-free shadows is needed. To avoid the high cost of mesh refinement associated with fast variations of visibility across...
