Detailed Description

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

Some of the algorithms here are (loosely) based on those found in: Graphics Gems II, ISBN 0-12-064480-0 pg. 247 "Fast Ray-Convex Polyhedron Intersection" Graphics Gems IV, ed. Paul Heckbert, ISBN 0-12-336156-7 T385.G6974 (1994) pg. 356 "Intersecting a Ray with a Cylinder"

Member Function Documentation

ConvertMaster2Top()

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

Intercept()

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

References dir.

Print()

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

pure virtual

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

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