  1. FF Variable Radii Poisson-Disk Sampling Scott A. Mitchell, Alexander Rand, Mohamed S. Ebeida, Chandrajit Bajaj Session 4B, Thursday Aug 9, 11:30-11:50 • Maximal Poisson-Disk Sampling is a particular statistical process for generating separated-yet-dense point clouds • Similar-yet-different from Delaunay Refinement and sphere packingsbetter output properties for certain apps • Motivation • Hot topic in Computer Graphics • for texture synthesis • Voronoi meshes for fracture mechanics • Two Contributions • Lipschitz conditions for spatially varying radii • Necessary condition for certain Graphics algs to work • New two-radii definition decoupled coverage and inhibition radii • Better “blue noise” • More random refinements Classic MPS coverage Two-radii MPS x exclusion
