Detailed Description

Struct which contains a cartesian approximation for any surface type. It contains a list of cartesian vertices in the global frame, and additionally a list of lists of indices which indicate which vertices form a face. Each entry in faces is a face, which is in turn a list of vertices that need to be connected to form a face. This allows the objString method to produce a ready-to-go obj output.

Constructor & Destructor Documentation

Acts::Polyhedron::Polyhedron ( )

default

Default constructor.

Acts::Polyhedron::Polyhedron	(	const std::vector< Vector3D > &	verticesIn,
		const std::vector< FaceType > &	facesIn,
		const std::vector< FaceType > &	triangularMeshIn,
		bool	radialCheck = `false`
	)

inline

Default constructor from a vector of vertices and a vector of faces

Parameters

verticesIn	The 3D global vertices that make up the object
facesIn	List of lists of indices for faces.
triangularMeshIn	List of lists of indices for a triangular mesh
radialCheck	A dedicated check for radial extent done

Note: This creates copies of the input vectors
