|
// Class Description:
|
|
// G4VVisManager is an abstract interface for the GEANT4 Visualization Manager.
|
|
// The inheritance hierarchy is:
|
|
// G4VVisManager <- G4VisManager <- YourVisManager
|
|
//
|
|
// See example/novice/N02 to see how to write YourVisManager and
|
|
// instantiate it. You should *not* access it directly; instead you
|
|
// should obtain a pointer as follows:
|
|
//
|
|
// G4VVisManager* pVVMan = G4VVisManager::GetConcreteInstance ();
|
|
//
|
|
// This ensures your code will link even if YourVisManager is not
|
|
// instantiated or even if not provided in a library. Please protect
|
|
// your code by testing the pointer, for example, by:
|
|
//
|
|
// if (pVVMan) pVVMan -> Draw (polyline);
|
|
//
|
|
// The Draw functions draw only "transient" objects. This is useful
|
|
// for debugging, e.g., drawing the step in your UserSteppingAction,
|
|
// since G4Steps are not kept.
|
|
//
|
|
// Note: to draw "permanent" objects, i.e., objects which are always
|
|
// available, such as detector geometry components, or available in an
|
|
// event after tracking has finished, such as hits, digitisations and
|
|
// trajectories, can be drawn in a transient way if you wish but it is
|
|
// usually possible to draw them in a permanent way with /vis/
|
|
// commands. The advantage is that permanent objects can be redrawn,
|
|
// e.g., when you change view or viewer; transient objects get
|
|
// forgotten.
|
|
//
|
|
// Note that the G4Transform3D argument refers to the transformation
|
|
// of the *object*, not the transformation of the coordinate syste.
|
|
//
|
|
// Note also that where a G4VisAttributes argument is specified, it
|
|
// overrides any attributes belonging to the object itself.
