Class Description

~TGLViewer()

void Draw()

 Draw out the the current viewer/scene

void PreDraw()

 GL work which must be done before each draw of scene

void PostDraw()

 GL work which must be done after each draw of scene

void Invalidate(UInt_t redrawLOD)

Bool_t Select(const TGLRect & rect)

 Select lock should already been taken in other thread in

void SetViewport(Int_t x, Int_t y, UInt_t width, UInt_t height)

void SetCurrentCamera(ECamera camera)

void SetupCameras(const TGLBoundingBox & box)
