FMeshSnapOpenBoundaries

Similar to [FMeshResolveTJunctions](API\Plugins\DynamicMesh\FMeshResolveTJunctions), but does not add any vertices to the mesh.

API > API/Plugins > API/Plugins/DynamicMesh

Similar to FMeshResolveTJunctions, but does not add any vertices to the mesh. Supports running multiple snapping iterations, because snapped-to edges may move in subsequent snaps.

Variables

Public

Name Type Remarks Include Path Unreal Specifiers
BoundaryEdges TSet< int32 > Subset of mesh boundary edges (otherwise all boundary edges are processed) Operations/MeshResolveTJunctions.h  
bPreventFlips bool Whether to avoid snapping in cases where doing so would locally flip a triangle Operations/MeshResolveTJunctions.h  
bSnapToEdges bool Whether vertices can be snapped to edges; otherwise, vertices are only snapped to other vertices Operations/MeshResolveTJunctions.h  
DistanceTolerance double Distance threshold used for various checks (eg is vertex on edge, end endpoint tolerance, etc) Operations/MeshResolveTJunctions.h  
MaxIterations int32 Maximum number of snapping iterations to perform Operations/MeshResolveTJunctions.h  
Mesh FDynamicMesh3 * The mesh that we are modifying Operations/MeshResolveTJunctions.h  
NumVertexSnaps int32 Number of vertex snaps performed (cumulative over iterations) Operations/MeshResolveTJunctions.h  
VertexSnapToleranceFactor double Scalar multiple of DistanceTolerance at which we snap a vertex directly to another vertex, rather than an edge Operations/MeshResolveTJunctions.h
