// The VisManager also has the concept of "current scene data" and

// those of any scene or view. When a view is drawn, it is given the
// current data and parameters; this might trigger "consequent
// actions", such as reconstruction of display lists. If the
// differences are minor, e.g, if only the viewpoint direction has
// changed, then it might not be necessary to reconstruct the display
// lists - each system must decide.
// Each scene comprises drawable objects such as detector components
// and hits when appropriate. A scene handler translates a scene into
// graphics-system-specific function calls and, possibly, a
// graphics-system-dependent database - display lists, scene graphs,
// etc. Each viewer has its "view parameters".
