Function Documentation

template<class MeshType >

void vcg::tri::PoissonPruning	(	MeshType &	m,
		std::vector< typename MeshType::VertexPointer > &	poissonSamples,
		float	radius,
		unsigned int	randSeed = 0
	)

Low level wrapper for Poisson Disk Pruning.

This function simply takes a mesh and a radius and returns a vector of vertex pointers listing the "surviving" points.

template<class MeshType >

void vcg::tri::PoissonPruning	(	MeshType &	m,
		std::vector< typename MeshType::CoordType > &	poissonSamples,
		float	radius,
		unsigned int	randSeed = 0
	)

Low level wrapper for Poisson Disk Pruning.

This function simply takes a mesh containing a point cloud to be pruned and a radius It returns a vector of CoordType listing the "surviving" points.

Definition at line 2296 of file point_sampling.h.

template<class MeshType >

void vcg::tri::PoissonPruningExact	(	MeshType &	m,
		std::vector< typename MeshType::VertexPointer > &	poissonSamples,
		typename MeshType::ScalarType &	radius,
		int	sampleNum,
		float	tolerance = 0.04,
		int	maxIter = 20,
		unsigned int	randSeed = 0
	)

Very simple wrapping for the Exact Poisson Disk Pruning.

This function simply takes a mesh and an expected number of points and returns vector of points. It performs multiple attempts with varius radii to correctly get the expected number of samples. It is obviously much slower than the other versions...

Parameters

poissonSamples	the mesh that has to be pruned
radius	the vector that will contain the chosen set of points
