◆ findHoleVertIdsByHoleEdges()

MRMESH_API HolesVertIds MR::PlanarTriangulation::findHoleVertIdsByHoleEdges ( const MeshTopology & tp,
const std::vector< EdgePath > & holePaths )

return vertices of holes that correspond internal contours representation of PlanarTriangulation

◆ getOutline()

MRMESH_API Contours2f MR::PlanarTriangulation::getOutline ( const Contours2f & contours,
ContoursIdMap * indicesMap = nullptr )

returns Contour representing outline if input contours indicesMap optional output from result contour ids to input ones

◆ getOutlineMesh()

MRMESH_API Mesh MR::PlanarTriangulation::getOutlineMesh ( const Contours2f & contours,
IntersectionsMap * interMap = nullptr )

returns Mesh with boundaries representing outline if input contours interMap optional output intersection map

◆ triangulateContours() [1/2]

MRMESH_API Mesh MR::PlanarTriangulation::triangulateContours ( const Contours2d & contours,
const HolesVertIds * holeVertsIds = nullptr )

triangulate 2d contours only closed contours are allowed (first point of each contour should be the same as last point of the contour)

Parameters
holeVertsIdsif set merge only points with same vertex id, otherwise merge all points with same coordinates
Returns
return created mesh

◆ triangulateContours() [2/2]

MRMESH_API Mesh MR::PlanarTriangulation::triangulateContours ( const Contours2f & contours,
const HolesVertIds * holeVertsIds = nullptr )

◆ triangulateDisjointContours() [1/2]

MRMESH_API std::optional< Mesh > MR::PlanarTriangulation::triangulateDisjointContours ( const Contours2d & contours,
const HolesVertIds * holeVertsIds = nullptr )

triangulate 2d contours only closed contours are allowed (first point of each contour should be the same as last point of the contour)

Parameters
holeVertsIdsif set merge only points with same vertex id, otherwise merge all points with same coordinates
Returns
std::optional<Mesh> : if some contours intersect return false, otherwise return created mesh

◆ triangulateDisjointContours() [2/2]

MRMESH_API std::optional< Mesh > MR::PlanarTriangulation::triangulateDisjointContours ( const Contours2f & contours,
