Constructor & Destructor Documentation

G4VParameterisationPolyhedra()

G4VParameterisationPolyhedra::G4VParameterisationPolyhedra	(	EAxis	axis,
		G4int	nCopies,
		G4double	offset,
		G4double	step,
		G4VSolid *	pSolid,
		DivisionType	divType )

Initialises a parameterised polyhedra, given the axis of parameterisation 'axis' and the number of divided slices 'nCopies'.

Parameters

[in]	axis	The axis along which apply the parameterisation.
[in]	nCopies	The total number of divided slices.
[in]	offset	Potential initial offset along the axis.
[in]	step	The width of the divided slice.
[in]	pSolid	Pointer to the original shape to parameterise.
[in]	divType	String identifier for the kind of division.
