Detailed Description

Generated from:  MR::FastWindingNumber

the class for fast approximate computation of winding number for a mesh (using its AABB tree)
Note, this used to be `[[nodiscard]]`, but GCC 12 doesn't understand both `[[...]]` and `__attribute__(...)` on the same class.
A possible fix is to change `MRMESH_CLASS` globally to `[[__gnu__::__visibility__("default")]]`.

Constructor & Destructor Documentation

__init__() [1/3]

None mrmeshpy.FastWindingNumber.__init__ ( * args, ** kwargs )

static

__init__() [2/3]

None mrmeshpy.FastWindingNumber.__init__	(		self,
		Mesh	mesh )

constructs this from AABB tree of given mesh;
this remains valid only if tree is valid

Implicit copy constructor.

Member Function Documentation

calcFromGrid()

None mrmeshpy.FastWindingNumber.calcFromGrid	(		self,
		std_vector_float	res,
		Vector3i	dims,
		AffineXf3f	gridToMeshXf,
		float	beta,
		func_bool_from_float	cb )

calculates winding numbers in each point from a three-dimensional grid
\\param res resulting winding numbers, will be resized automatically
\\param dims dimensions of the grid
\\param gridToMeshXf transform from integer grid locations to voxel's centers in mesh reference frame
\\param beta determines the precision of the approximation: the more the better, recommended value 2 or more

Reimplemented from mrmeshpy.IFastWindingNumber.

calcFromGridWithDistances()

None mrmeshpy.FastWindingNumber.calcFromGridWithDistances	(		self,
		std_vector_float	res,
		Vector3i	dims,
		AffineXf3f	gridToMeshXf,
		DistanceToMeshOptions	options,
		func_bool_from_float	cb )

calculates distances with the sign obtained from generalized winding number in each point from a three-dimensional grid;
if sqr(res) < minDistSq or sqr(res) >= maxDistSq, then NaN is returned for such point
\\param res resulting signed distances, will be resized automatically
\\param dims dimensions of the grid

Reimplemented from mrmeshpy.IFastWindingNumber.

calcFromVector()

None mrmeshpy.FastWindingNumber.calcFromVector	(		self,
		std_vector_float	res,
		std_vector_Vector3_float	points,
		float	beta,
		FaceId	skipFace,
		func_bool_from_float	cb )

see methods' descriptions in IFastWindingNumber

Reimplemented from mrmeshpy.IFastWindingNumber.

calcSelfIntersections()

None mrmeshpy.FastWindingNumber.calcSelfIntersections	(		self,
		FaceBitSet	res,
		float	beta,
		func_bool_from_float	cb )

calculates winding numbers for all centers of mesh's triangles. if winding number is less than 0 or greater then 1, that face is marked as self-intersected
\\param res resulting bit set
\\param beta determines the precision of the approximation: the more the better, recommended value 2 or more

Reimplemented from mrmeshpy.IFastWindingNumber.

calcWithDistances()

float mrmeshpy.FastWindingNumber.calcWithDistances	(		self,
		Vector3f	p,
		DistanceToMeshOptions	options )
