ComputeClusterCornerVertices()

void GEOMETRYCORE_API UE::Geometry::FaceNormalClustering::ComputeClusterCornerVertices	(	FDynamicMesh3 &	Mesh,
		TArray< int32 > &	OutCornerVertices,
		const FClusterOptions &	Options,
		TSet< int32 > *	IgnoreEdges = nullptr
	)

Find the vertices at the corners of face clusters – i.e., vertices which touch faces from three or more clusters

Parameters

Mesh	The Mesh to operate on
OutCornerVertices	All vertices which touch at least three clusters
Options	Options controlling the tolerances used for clustering
IgnoreEdges	Optional set of edges that clusters should not be merged across

ComputeMeshPolyGroupsFromClusters()

void GEOMETRYCORE_API UE::Geometry::FaceNormalClustering::ComputeMeshPolyGroupsFromClusters	(	FDynamicMesh3 &	Mesh,
		TArray< TArray< int32 > > &	OutPolyGroups,
		const FClusterOptions &	Options,
		TSet< int32 > *	IgnoreEdges = nullptr
	)

Find Mesh PolyGroups by clustering neighboring faces (or polygroups) with similar normals.

Parameters

Mesh	The Mesh to operate on
OutPolyGroups	An array holding the array-of-triangle-IDs for each found PolyGroup
Options	Options controlling the tolerances used for clustering
IgnoreEdges	Optional set of edges that clusters should not be merged across
