Detailed Description

Function Documentation

◆ equalizeTriAreas()

MRMESH_API bool MR::equalizeTriAreas	(	Mesh &	mesh,
		const MeshEqualizeTriAreasParams &	params = {},
		ProgressCallback	cb = {} )

applies given number of iterations with movement toward vertexPosEqualNeiAreas() to the whole mesh ( or some region if it is specified )

Returns: true if the operation completed succesfully, and false if it was interrupted by the progress callback.

◆ hardSmoothTetrahedrons()

MRMESH_API void MR::hardSmoothTetrahedrons	(	Mesh &	mesh,
		const VertBitSet *	region = nullptr )

move all region vertices with exactly three neighbor vertices in the center of the neighbors

◆ relax()

MRMESH_API bool MR::relax	(	Mesh &	mesh,
		const MeshRelaxParams &	params = {},
		ProgressCallback	cb = {} )

applies given number of relaxation iterations to the whole mesh ( or some region if it is specified )

Returns: true if was finished successfully, false if was interrupted by progress callback

◆ relaxApprox()

MRMESH_API bool MR::relaxApprox	(	Mesh &	mesh,
		const MeshApproxRelaxParams &	params = {},
		ProgressCallback	cb = {} )

applies given number of relaxation iterations to the whole mesh ( or some region if it is specified ) approx neighborhoods

Returns: true if the operation completed succesfully, and false if it was interrupted by the progress callback.

◆ relaxKeepVolume()

MRMESH_API bool MR::relaxKeepVolume	(	Mesh &	mesh,
		const MeshRelaxParams &	params = {},
		ProgressCallback	cb = {} )

applies given number of relaxation iterations to the whole mesh ( or some region if it is specified )
do not really keeps volume but tries hard

Returns: true if the operation completed succesfully, and false if it was interrupted by the progress callback.

◆ removeSpikes()

MRMESH_API void MR::removeSpikes	(	Mesh &	mesh,
		int	maxIterations,
		float	minSumAngle,
		const VertBitSet *	region = nullptr )

applies at most given number of relaxation iterations the spikes detected by given threshold

◆ smoothRegionBoundary()

MRMESH_API void MR::smoothRegionBoundary	(	Mesh &	mesh,
		const FaceBitSet &	regionFaces,
		int	numIters = 4 )

given a region of faces on the mesh, moves boundary vertices of the region to make the region contour much smoother with minor optimiziztion of mesh topology near region boundary;

Parameters

numIters >= 1 how many times to run the algorithm to achive a better quality, solution is typically oscillates back and forth so even number of iterations is recommended

◆ vertexPosEqualNeiAreas()

MRMESH_API Vector3f MR::vertexPosEqualNeiAreas	(	const Mesh &	mesh,
		VertId	v,
		bool	noShrinkage )

computes position of a vertex, when all neighbor triangles have almost equal areas, more precisely it minimizes sum_i (area_i)^2 by adjusting the position of this vertex only
