Variable Radii Poisson-Disk Sampling Scott A. Mitchell, Alexander Rand, Mohamed S. Ebeida and Chadrajit Bajaj In proceedings of 24th Canadian Conference on Computational Geometry 2012 Just-this-paper downloads: faster local mirror print and online; of conference site print and online. The print version is 6-pages in black and white. The online version is in color with better figures and an appendix with proofs and experiments. Both versions are part of the official CCCG proceedings. I also described this spatial statistics open problem of characterizing the spectrum of Poisson-disk packings, and Delaunay Refinement output, and defining an ideal spectrum for computer graphics. talk slides pptx and keynote and pdf --- preview slide pdf and pptx. bibtex-print and bibtex-online |
