Member Function Documentation

calcFromGrid()

None mrmeshpy.IFastWindingNumber.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 in mrmeshpy.FastWindingNumber.

calcFromGridWithDistances()

None mrmeshpy.IFastWindingNumber.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 in mrmeshpy.FastWindingNumber.

calcFromVector()

None mrmeshpy.IFastWindingNumber.calcFromVector	(		self,
		std_vector_float	res,
		std_vector_Vector3_float	points,
		float	beta,
		FaceId	skipFace = ...,
		func_bool_from_float	cb = '{}' )

calculates winding numbers in the points from given vector
\\param res resulting winding numbers, will be resized automatically
\\param points incoming points
\\param beta determines the precision of the approximation: the more the better, recommended value 2 or more
\\param skipFace this triangle (if it is close to `q`) will be skipped from summation

Reimplemented in mrmeshpy.FastWindingNumber.

calcSelfIntersections()

None mrmeshpy.IFastWindingNumber.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 in mrmeshpy.FastWindingNumber.
