Detailed Description

Abstract class for fast approximate computation of generalized winding number for a mesh (using its AABB tree) Generated from class MR::IFastWindingNumber. Derived classes: Direct: (non-virtual) MR::Cuda::FastWindingNumber MR::FastWindingNumber

Instances created here own their C++ objects, see CppObject.

Constructor & Destructor Documentation

IFastWindingNumber()

meshlib.IFastWindingNumber.IFastWindingNumber	(	java.lang.foreign.MemorySegment	ptr,
		boolean	owned,
		java.lang.Object	owner )

Wraps a pointer from the C bindings. If owned, the object is destroyed when the wrapper dies. owner is kept alive as long as this wrapper is. Not for normal use.

Member Function Documentation

calcFromGrid()

void meshlib.IFastWindingNumber.calcFromGrid	(	meshlib.std_vector_float	res,
		meshlib.Vector3i	dims,
		meshlib.AffineXf3f	gridToMeshXf,
		float	beta,
		meshlib.std_function_bool_from_float	cb )

calculates winding numbers in each point from a three-dimensional grid

Parameters

res	resulting winding numbers, will be resized automatically
dims	dimensions of the grid
gridToMeshXf	transform from integer grid locations to voxel's centers in mesh reference frame
beta	determines the precision of the approximation: the more the better, recommended value 2 or more Generated from method MR::IFastWindingNumber::calcFromGrid.

Calls MR_IFastWindingNumber_calcFromGrid(). The C++ function returns expected<void, std::string>: the value is returned and an error is thrown as UnexpectedResultException.

calcFromGridWithDistances()

void meshlib.IFastWindingNumber.calcFromGridWithDistances	(	meshlib.VoxelScalars	res,
		meshlib.Vector3i	dims,
		meshlib.AffineXf3f	gridToMeshXf,
		meshlib.DistanceToMeshOptions	options,
		meshlib.std_function_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

Parameters

res	resulting signed distances, will be resized automatically
dims	dimensions of the grid Generated from method MR::IFastWindingNumber::calcFromGridWithDistances.

Calls MR_IFastWindingNumber_calcFromGridWithDistances(). The C++ function returns expected<void, std::string>: the value is returned and an error is thrown as UnexpectedResultException.

calcFromVector()

void meshlib.IFastWindingNumber.calcFromVector	(	meshlib.std_vector_float	res,
		meshlib.std_vector_MR_Vector3f	points,
		float	beta,
		meshlib.FaceId	skipFace,
		meshlib.std_function_bool_from_float	cb )

calculates winding numbers in the points from given vector

Parameters

res	resulting winding numbers, will be resized automatically
points	incoming points
beta	determines the precision of the approximation: the more the better, recommended value 2 or more
skipFace	this triangle (if it is close to q) will be skipped from summation Generated from method MR::IFastWindingNumber::calcFromVector.

Calls MR_IFastWindingNumber_calcFromVector(). The C++ function returns expected<void, std::string>: the value is returned and an error is thrown as UnexpectedResultException.

calcSelfIntersections()

void meshlib.IFastWindingNumber.calcSelfIntersections	(	meshlib.FaceBitSet	res,
		float	beta,
		meshlib.std_function_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

Parameters

res	resulting bit set
beta	determines the precision of the approximation: the more the better, recommended value 2 or more Generated from method MR::IFastWindingNumber::calcSelfIntersections.

Calls MR_IFastWindingNumber_calcSelfIntersections(). The C++ function returns expected<void, std::string>: the value is returned and an error is thrown as UnexpectedResultException.
