Classes

	Name	Description
	FBoxShape3d	FBoxShape is a 3D oriented box
	FCapsuleShape3d	FCapsuleShape is a 3D oriented capsule/sphyl
	FConvexShape3d	FConvexShape is a 3D convex hull, currently stored as a triangle mesh
	FMeshSimpleShapeApproximation	FMeshSimpleShapeApproximation can calculate various "simple" shape approximations for a set of meshes, by fitting various primitives/hulls/etc to each mesh.
	FSimpleShapeSet3d	FSimpleShapeSet stores a set of simple geometry shapes useful for things like collision detection/etc.

Functions

		Name	Description
	bool	UE::Geometry::IsBoxMesh ( const FDynamicMesh3& Mesh, FOrientedBox3d& BoxOut, double AngleToleranceDeg )	Detect if input Mesh is a meshed box, and if so return analytic box in BoxOut.
	bool	UE::Geometry::IsCapsuleMesh ( const FDynamicMesh3& Mesh, FCapsule3d& CapsuleOut, double RelativeDeviationTol )	Detect if input Mesh is a meshed approximation of an analytic Capsule, and if so return best guess in CapsuleOut.
	bool	UE::Geometry::IsSphereMesh ( const FDynamicMesh3& Mesh, FSphere3d& SphereOut, double RelativeDeviationTol )	Detect if input Mesh is a meshed approximation of an analytic Sphere, and if so return best guess in SphereOut.
