Detailed Description

Some simple volumes that know how to calculate where a ray intercepts them.

Member Function Documentation

virtual void genie::geometry::FidShape::ConvertMaster2Top ( const ROOTGeomAnalyzer * rgeom )

pure virtual

derived classes must implement the ConvertMaster2Top() method which transforms the shape specification from master coordinates to "top vol"

Implemented in genie::geometry::FidPolyhedron, genie::geometry::FidCylinder, and genie::geometry::FidSphere.

Referenced by genie::geometry::GeomVolSelectorFiducial::ConvertShapeMaster2Top(), and genie::geometry::GeomVolSelectorRockBox::MakeRockBox().

virtual RayIntercept genie::geometry::FidShape::Intercept	(	const TVector3 &	start,
		const TVector3 &	dir
	)		const

pure virtual

derived classes must implement the Intercept() method which calculates the entry/exit point of a ray w/ the shape

Implemented in genie::geometry::FidPolyhedron, genie::geometry::FidCylinder, and genie::geometry::FidSphere.

Referenced by genie::geometry::GeomVolSelectorRockBox::BeginPSList(), and genie::geometry::GeomVolSelectorFiducial::BeginPSList().

virtual void genie::geometry::FidShape::Print ( std::ostream & stream ) const

pure virtual

Implemented in genie::geometry::FidPolyhedron, genie::geometry::FidCylinder, and genie::geometry::FidSphere.

Referenced by genie::geometry::operator<<().
