MRCUDA_API Expected< void > MR::Cuda::FastWindingNumber::calcFromGrid ( std::vector< float > & res, const Vector3i & dims, const AffineXf3f & gridToMeshXf, float beta, const ProgressCallback & cb )

overridevirtual

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

Implements MR::IFastWindingNumber.

MRCUDA_API Expected< void > MR::Cuda::FastWindingNumber::calcFromGridByParts ( GridByPartsFunc resFunc, const Vector3i & dims, const AffineXf3f & gridToMeshXf, float beta, int layerOverlap, const ProgressCallback & cb )

overridevirtual

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

Parameters

resFunc	callback that gets a block of resulting winding numbers
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

overridevirtual

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

resFunc	callback that gets a block of resulting winding numbers
dims	dimensions of the grid
gridToMeshXf	transform from integer grid locations to voxel's centers in mesh reference frame
layerOverlap	overlap between two blocks of the grid, set as XY layer count

Implements MR::IFastWindingNumberByParts.

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

Implements MR::IFastWindingNumber.

calcSelfIntersections()

MRCUDA_API Expected< void > MR::Cuda::FastWindingNumber::calcSelfIntersections ( FaceBitSet & res, float beta, const ProgressCallback & cb )

overridevirtual

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
