calcFromGridByParts()

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

pure virtual

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
layerOverlap	overlap between two blocks of the grid, set as XY layer count

Implemented in MR::Cuda::FastWindingNumber.

calcFromGridWithDistancesByParts()

virtual Expected< void > MR::IFastWindingNumberByParts::calcFromGridWithDistancesByParts ( GridByPartsFunc resFunc, const Vector3i & dims, const AffineXf3f & gridToMeshXf, const DistanceToMeshOptions & options, int layerOverlap, 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

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

Implemented in MR::Cuda::FastWindingNumber.
