		VtnCounter &	vtnCounter,
		double	scalor,
		const std::vector< Acts::Vector3D > &	vertices,
		double	thickness = 0.,
		const std::vector< unsigned int > &	vsides = {}
	)

This will write a planar face

• normal is given by cross product

Parameters

stream	is the stream where to write to
face	is the face to be written out
cvertex	is the current vertex number
thickness	is the (optional) thickness
