Paolo Cignoni 28d838ca49 Corrected a small bug in the poisson sampling exact number helper. 2014-05-23 15:05:16 +00:00
Paolo Cignoni 3b7753ef20 Many Changes to point sampling: 
- Heavy refactoring (typename changes, declaration etc) for clarity and shortness
- add a reset() method to the sampler interface
- changed the way used to get a weight in the sampling process now the variance is used to map the 'metric' along 1 and <variance>; Made it uniform in poisson and montecarlo sampling.
- changed the way in which the weight is used/passed: now with attribute!
- added exact number poisson disk pruning.
- stats are always computed (no performance impact clearer code)

Paolo Cignoni 4be7b59a80 Added TrivialPointerSampler to sample a mesh returning pointers to the chosen vertexes. 
Added another poisson pruning wrapper to make even easier to choose a subset of vertexes from a mesh with good distribution.

Paolo Cignoni 2254e98779 slightly improved comments and a missing requirement 2014-03-04 00:39:27 +00:00
Marco Callieri 0ba814697c Poisson sampling was ignoring the DELETED flag, so when a part of a mesh was deleted but still in memory, would sample it. added a couple of if(!(*vi).IsD()) tests in [InitSpatialHashTable], [ComputePoissonSampleRadii] and [PoissonDiskPruning]. 
Seems to work, but please test it. 
Beware: there could be more places where this is needed; I only checked poisson.
