WebDec 1, 2010 · A novel method called Progressive Sample Projection is introduced that can generate massive Poisson-disk samples on mesh surfaces in very short time by … WebAbstract. We solve the problem of generating a uniform Poisson-disk sampling that is both maximal and unbiased over bounded non-convex domains. To our knowledge this is the first provably correct algorithm with time and space dependent only on the number of points produced. Our method has two phases, both based on classical dart-throwing.
