Member Function Documentation

ComputeTransformation()

void G4tgbPlaceParamCircle::ComputeTransformation ( const G4int no, G4VPhysicalVolume * pv ) const

virtual

Computes the transformation for the 'pv' volume and replica number 'no'. It is a required method, as it is the reason for this class.

Parameters

[in]	pv	Pointer to the current physical volume.
[in]	no	The copy number index.

Reimplemented from G4tgbPlaceParameterisation.
