◆ calcFromGrid()

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

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

Parameters
resresulting winding numbers, will be resized automatically
dimsdimensions of the grid
gridToMeshXftransform from integer grid locations to voxel's centers in mesh reference frame
betadetermines the precision of the approximation: the more the better, recommended value 2 or more

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

◆ calcFromGridWithDistances()

virtual VoidOrErrStr MR::IFastWindingNumber::calcFromGridWithDistances ( std::vector< float > & res,
const Vector3i & dims,
const AffineXf3f & gridToMeshXf,
float windingNumberThreshold,
float beta,
float maxDistSq,
float minDistSq,
ProgressCallback cb )
pure virtual

calculates distances with the sign obtained from winding number in each point from a three-dimensional grid

Parameters
resresulting signed distances, will be resized automatically
dimsdimensions of the grid
gridToMeshXftransform from integer grid locations to voxel's centers in mesh reference frame
windingNumberThresholdpositive distance if winding number below or equal this threshold
betadetermines the precision of the approximation: the more the better, recommended value 2 or more

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

◆ calcFromVector()

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

calculates winding numbers in the points from given vector

Parameters
resresulting winding numbers, will be resized automatically
pointsincoming points
betadetermines the precision of the approximation: the more the better, recommended value 2 or more
skipFacethis triangle (if it is close to q) will be skipped from summation

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

◆ calcSelfIntersections()

virtual bool MR::IFastWindingNumber::calcSelfIntersections ( FaceBitSet & res,
float beta,
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
resresulting bit set
betadetermines the precision of the approximation: the more the better, recommended value 2 or more
Returns
false if the operation was canceled by the user

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