getMonotonePlan()

unsafe MR.Std.Optional_MRHoleFillPlan MR.PlanarTriangulation.getMonotonePlan ( MR.Const_Mesh mesh, MR.Std.Const_Vector_StdVectorMREdgeId loops, in MR.Vector3f normal )

inlinestatic

splits the near-planar region bounded by loops in monotone parts, without triangulating them this is the sweep-line triangulation stopped right after monotonation

Parameters

loops	one closed EdgeLoop of at least 3 edges per boundary of one region, bounding holes of mesh as trackRightBoundaryLoop returns them; which way round a loop runs does not matter
normal	the orientation the region is monotone around, see triangulateDisjointContours

Returns

std::nullopt if the loops intersect or a chord would land in a face instead of a hole, so that the caller can fall back on filling every loop separately; otherwise a plan with numTris == 0 for executeHoleFillPlan, which then only adds edges (empty if already monotone, a no-op). Validate it with isFillingMultipleEdgeFree: a chord may duplicate an off-loop mesh edge Generated from function MR.PlanarTriangulation.getMonotonePlan.

inlinestatic

triangulate hole boundary loops of mesh in the mesh's own 3d space, orienting faces around normal combinatorics run on the dominant-axis projection of normal; output vertices keep the exact mesh coordinates (no projection round-trip), and loops sharing a mesh vertex are merged by identity.

Parameters

loops	one closed EdgeLoop per contour (as produced by trackRightBoundaryLoop on each hole edge)
outPatchMap	optional output: for each patch boundary edge (by undirected id) the mesh edge it copies, directed along it; edges past its size are the triangulation's own
