TArray<FIndex3i> UE::Geometry::FFlatTriangulationMeshGenerator::Triangles2D

Source triangle indices

◆ Triangles2DPolygroups

TArray<int> UE::Geometry::FFlatTriangulationMeshGenerator::Triangles2DPolygroups

Optional polygroup IDs per triangle – ignored if empty

◆ Vertices2D

TArray<FVector2d> UE::Geometry::FFlatTriangulationMeshGenerator::Vertices2D

Vertices of 2D triangulation.
