Further experience with controller-based automatic motion synthesis for articulated figures
Joel Auslander, Alex Fukunaga, Hadi Partovi, Jon Christensen, Lloyd Hsu, Peter Reiss, Andrew Shuman, Joe Marks, J. Thomas Ngo
Pages: 311-336
DOI: 10.1145/225294.225295
We extend an earlier automatic motion-synthesis algorithm for physically realistic articulated figures in several ways. First, we summarize several incremental improvements to the original algorithm that improve its efficiency significantly and...

Smooth B-spline illumination maps for bidirectional ray tracing
Richard A. Redner, Mark E. Lee, Samuel P. Uselton
Pages: 337-362
DOI: 10.1145/225294.225296
In this paper we introduce B-spline illumination maps and their generalizations and extensions for use in realistic image generation algorithms. The B-spline lighting functions (i.e., illumination maps) are defined as weighted probability...

Hierarchical triangulation for multiresolution surface description
Leila De Floriani, Enrico Puppo
Pages: 363-411
DOI: 10.1145/225294.225297
A new hierarchical triangle-based model for representing surfaces over sampled data is proposed, which is based on the subdivision of the surface domain into nested triangulations, called a hierarchical triangulation (HT). The...
