class TGLViewer: public TVirtualViewer3D, public TGLViewerBase


 Base GL viewer object - used by both standalone and embedded (in pad)
 GL. Contains core viewer objects :

 GL scene - collection of main drawn objects - see TGLStdScene
 Cameras (fXXXXCamera) - ortho and perspective cameras - see TGLCamera
 Clipping (fClipXXXX) - collection of clip objects - see TGLClip
 Manipulators (fXXXXManip) - collection of manipulators - see TGLManip

 It maintains the current active draw styles, clipping object,
 manipulator, camera etc.

 TGLViewer is 'GUI free' in that it does not derive from any ROOT GUI
 TGFrame etc - see TGLSAViewer for this. However it contains GUI
 GUI style methods HandleButton() etc to which GUI events can be
 directed from standalone frame or embedding pad to perform

 For embedded (pad) GL this viewer is created directly by plugin
 manager. For standalone the derived TGLSAViewer is.

Function documentation

TGLViewer(TVirtualPad* pad, Int_t x, Int_t y, Int_t width, Int_t height)
 Construct the viewer object, with following arguments:
    'pad' - external pad viewer is bound to
    'x', 'y' - initial top left position
    'width', 'height' - initial width/height
TGLViewer(TVirtualPad * pad)
gl-embedded viewer's ctor
 Construct the viewer object, with following arguments:
    'pad' - external pad viewer is bound to
    'x', 'y' - initial top left position
    'width', 'height' - initial width/height
void InitSecondaryObjects()
 Common initialization.
 Destroy viewer object.
void PadPaint(TVirtualPad* pad)
 Entry point for updating viewer contents via VirtualViewer3D
 We search and forward the request to appropriate TGLScenePad.
 If it is not found we create a new TGLScenePad so this can
 potentially also be used for registration of new pads.
void UpdateScene()
 Force update of pad-scenes. Eventually this could be generalized
 to all scene-types via a virtual function in TGLSceneBase.
void ResetCurrentCamera()
 Resets position/rotation of current camera to default values.
void SetupCameras(Bool_t reset)
 Setup cameras for current bounding box.
void PostSceneBuildSetup(Bool_t resetCameras)
 Perform post scene-build setup.
void InitGL()
 Initialise GL state if not already done
void RequestDraw(Short_t LOD = TGLRnrCtx::kLODMed)
 Post request for redraw of viewer at level of detail 'LOD'
 Request is directed via cross thread gVirtualGL object.
void PreRender()
void DoDraw()
 Draw out the the current viewer/scene
void DrawGuides()
 Draw reference marker and coordinate axes.
void DrawCameraMarkup()
 Draw camera markup overlay.
void DrawDebugInfo()
 If in debug mode draw camera aids and overall bounding box.
void PreDraw()
 Perform GL work which must be done before each draw of scene
void PostDraw()
 Perform GL work which must be done after each draw of scene
void MakeCurrent()
 Make GL context current
void SwapBuffers()
 Swap GL buffers
Bool_t RequestSelect(Int_t x, Int_t y, Bool_t trySecSel = kFALSE)
 Post request for select draw of viewer, picking objects round the WINDOW
 point (x,y).
 Request is directed via cross thread gVirtualGL object
Bool_t DoSelect(Int_t x, Int_t y, Bool_t trySecSel = kFALSE)
 Perform GL selection, picking objects overlapping WINDOW
 area described by 'rect'. Return kTRUE if selection should be
 changed, kFALSE otherwise.
 Select lock should already been taken in other thread in
void ApplySelection()
 Process result from last selection (in fSelRec) and
 extract a new current selection from it.
 Here we only use physical shape.
Bool_t RequestOverlaySelect(Int_t x, Int_t y)
 Post request for select draw of viewer, picking objects round the WINDOW
 point (x,y).
 Request is directed via cross thread gVirtualGL object
Bool_t DoOverlaySelect(Int_t x, Int_t y)
 Perform GL selection, picking overlay objects only.
 Return TRUE if the selected overlay-element has changed.
void SetViewport(Int_t x, Int_t y, Int_t width, Int_t height)
 Set viewer viewport (window area) with bottom/left at (x,y), with
 dimensions 'width'/'height'
TGLCamera& RefCamera(TGLViewer::ECameraType camera)
 Return camera reference by type.
void SetCurrentCamera(TGLViewer::ECameraType camera)
 Set current active camera - 'cameraType' one of:
 kCameraPerspX, kCameraPerspY, kCameraPerspZ
 kCameraOrthoXOY, kCameraOrthoXOZ, kCameraOrthoZOY
void SetOrthoCamera(TGLViewer::ECameraType camera, Double_t zoom, Double_t dolly, Double_t* center, Double_t hRotate, Double_t vRotate)
 Set an orthographic camera to supplied configuration - note this
 does not need to be the current camera - though you will not see
 the effect if it is not.

 'camera' defines the ortho camera - one of kCameraOrthoXOY / XOZ / ZOY
 'left' / 'right' / 'top' / 'bottom' define the WORLD coordinates which
 corresepond with the left/right/top/bottom positions on the GL viewer viewport
 E.g. for kCameraOrthoXOY camera left/right are X world coords,
 top/bottom are Y world coords
 As this is an orthographic camera the other axis (in eye direction) is
 no relevant. The near/far clip planes are set automatically based in scene
void SetPerspectiveCamera(TGLViewer::ECameraType camera, Double_t fov, Double_t dolly, Double_t* center, Double_t hRotate, Double_t vRotate)
 Set a perspective camera to supplied configuration - note this
 does not need to be the current camera - though you will not see
 the effect if it is not.

 'camera' defines the persp camera - one of kCameraPerspXOZ, kCameraPerspYOZ, kCameraPerspXOY
 'fov' - field of view (lens angle) in degrees (clamped to 0.1 - 170.0)
 'dolly' - distance from 'center'
 'center' - world position from which dolly/hRotate/vRotate are measured
             camera rotates round this, always facing in (in center of viewport)
 'hRotate' - horizontal rotation from initial configuration in degrees
 'hRotate' - vertical rotation from initial configuration in degrees
void GetGuideState(Int_t& axesType, Bool_t& axesDepthTest, Bool_t& referenceOn, Double_t* referencePos) const
 Fetch the state of guides (axes & reference markers) into arguments
void SetGuideState(Int_t axesType, Bool_t axesDepthTest, Bool_t referenceOn, const Double_t* referencePos)
 Set the state of guides (axes & reference markers) from arguments.
void SetDrawCameraCenter(Bool_t x)
 Draw camera look at and rotation point.
const TGLPhysicalShape * GetSelected()
 Return selected physical shape.
void SelectionChanged()
 Emit signal indicating selection has changed.
void OverlayDragFinished()
 Emit signal indicating that an overlay drag has finished.
Int_t DistancetoPrimitive(Int_t px, Int_t py)
 Calcaulate and return pixel distance to nearest viewer object from
 window location px, py
 This is provided for use when embedding GL viewer into pad
void ExecuteEvent(Int_t event, Int_t px, Int_t py)
 Process event of type 'event' - one of EEventType types,
 occuring at window location px, py
 This is provided for use when embedding GL viewer into pad
Bool_t HandleEvent(Event_t* ev)
 Handle generic Event_t type 'event' - provided to catch focus changes
 and terminate any interaction in viewer.
Bool_t HandleButton(Event_t* ev)
 Handle mouse button 'event'.
Bool_t HandleDoubleClick(Event_t* ev)
 Handle mouse double click 'event'.
Bool_t HandleConfigureNotify(Event_t* ev)
 Handle configure notify 'event' - a window resize/movement.
Bool_t HandleKey(Event_t* ev)
 Handle keyboard 'event'.
Bool_t HandleMotion(Event_t* ev)
 Handle mouse motion 'event'.
Bool_t HandleExpose(Event_t* ev)
 Handle window expose 'event' - show.
