Paolo Cignoni b572187a63 added yet another wrapper for the Allocator Add face. it is quite useful to add faces just with indexes... 2014-05-15 16:31:39 +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)

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.
 2014-01-21 14:59:45 +00:00
Marco Callieri 17ed6bdac4 in the function used to compute normals for pointclouds, added a check during consensus propagation to avoid flipping normals backface w.r.t. the specified wiewposition. 
It does seem redundant, but it may happen, by mere chance, that the starting point used for consensus propagation, forces other points to flip even if the resulting flip places them backface w.r.t. the specified wiewposition
--to be tested--

Paolo Cignoni 993a9a2c5b Tricky Change to the refine interface. Now the edge and midpoint predicate are passed as reference so if you need you can make predicate with state. This is useful when the edge and midpoint predicate share a lot of common information and you want exploit the computation done in the edge predicate (e.g. sometimes when you decide if an edge has to be split you already know where the vertex should be placed). 2013-11-28 23:29:06 +00:00
