calcFromGrid()

virtual Expected< void > MR::IFastWindingNumber::calcFromGrid ( std::vector< float > & res, const Vector3i & dims, const AffineXf3f & gridToMeshXf, float beta, const ProgressCallback & cb = {} )

pure virtual

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

Implemented in MR::Cuda::FastWindingNumber, and MR::FastWindingNumber.

calcFromGridWithDistances()

virtual Expected< void > MR::IFastWindingNumber::calcFromGridWithDistances ( std::vector< float > & res, const Vector3i & dims, const AffineXf3f & gridToMeshXf, const DistanceToMeshOptions & options, const ProgressCallback & cb )

pure virtual

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

Implemented in MR::Cuda::FastWindingNumber, and MR::FastWindingNumber.

calcFromVector()

virtual Expected< void > MR::IFastWindingNumber::calcFromVector ( std::vector< float > & res, const std::vector< Vector3f > & points, float beta, FaceId skipFace = {}, const ProgressCallback & cb = {} )

pure virtual

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

Implemented in MR::Cuda::FastWindingNumber, and MR::FastWindingNumber.

calcSelfIntersections()

virtual Expected< void > MR::IFastWindingNumber::calcSelfIntersections ( FaceBitSet & res, float beta, const ProgressCallback & cb = {} )

pure virtual

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

Implemented in MR::Cuda::FastWindingNumber, and MR::FastWindingNumber.
