// SendWireframeTo (G4VGraphicsModel&).
|
|
// 22.07.96 J.Allison Changed G4VGraphicsModel to G4VGraphicsScene.

// and SendPolyhedronTo to CreatePolyhedron.
|
|
// 27.03.98 J.Apostolakis Inherit from G4CSGSolid (not G4VSolid).
|
|
// 18.11.99 J.Apostolakis, V.Grichine: kUndefined was added to ESide
