From Matevz:
Major restructuring of GL viewer-scene relationship (Matevz)
===================================================
The main idea was to generalize current GL infrustructure so that the
following features can be done in the future:
1. Full pad rendering via GL including 3D histo/func painters and 2D graphics.
2. Implementation of GL canvas (with independent viewers serving as pads).
3. Multi-view event-visualization front-end.
4. Inclusion of external scenes (non-ROOT-gl) in ROOT viewer.
Rendering of ROOT scenes in external GL frameworks.
Changes on the code level
-------------------------
0. Extend current scene/viewer classes into a 2-level class hierarchy.
New classes TGLViewerBase and TGLSceneBase.
1. Allow scenes to be shared among viewers. View-specific scene-cache
needs to be kept at the viewer side.
2. Viewer now manages a list of scenes. It is possible to put together
a combination of scenes (e.g. one showing geometry, another one tracks
and yet another clusters). Each scene can define its own clipping object.
3. Provide API for fine-grained control over rendered object removal,
creation and update. This allows for efficient scene-updates.
4. Disentangle selection, clipping and other markup objects from
within viewer-scene singleton.
New classes TGLClipSet, TGLManipSet.
6. Disentangle selection management.
7. Separate overlay rendering to allow any number of active GL-GUI
elements (like manipulators are now).
New classes TGLOverlayElement.
8. Trailing white space has been removed in all files.
Restructure low-level interface to OpenGL (Timur)
=========================================
1. Allow sharing GL resources among viewers.
2. Do not bind GL-output (windowed or offscreen) to ROOT GUI.
New classes TGLContext, TGLFormat, TGLWidget.
This oboletes TGLKernel and TVirtualGL classes.

- TGLSAViewer::SavePicture is now a public method. Therefore it is now
possible to generate gif files of the GL-Viewer from the command line
doing:
root [1] TGLSAViewer *glv = (TGLSAViewer *)gPad->GetViewer3D();
root [2] glv->SavePicture("gl.gif");
TGLSAViewer::SavePicture has also been modified to allow to generate
animated gif files. Example:
root [1] TGLSAViewer *glv = (TGLSAViewer *)gPad->GetViewer3D();
root [2] glv->SavePicture("gl.gif+");
root [3] glv->SavePicture("gl.gif+");
root [4] glv->SavePicture("gl.gif+");
Between each call to glv->SavePicture("gl.gif+"), the GL-Viewer display
has been modified. Then gl.gif is an amination build from the various
images displayed in the GL-Viewer.

From Matevz and Timur:
* gl/inc/TGLViewer.h:
* gl/src/TGLViewer.cxx:
Added customizations of update/redraw behaviour:
1) flag 'Bool_t fIgnoreSizesOnUpdate' that tells the viewer
not to check the size of the object in AddObject();
2) member 'Color_t fClearColor' that allows user to select the
background color;
3) method 'void UpdateScene()' thet forces the scene update via
calling 'fPad->Paint()';
4) method 'virtual void RefreshPadEditor(TObject* changed=0)' that
allows updates to be sent to the built-in editor when the
internal state changes.
* gl/inc/TGLSAViewer.h:
* gl/src/TGLSAViewer.cxx:
Implemented virtual 'TGLSAViewer::RefreshPadEditor()'. In all
calls to 'TGedEditor::SetModel()' replaced third argument 'Int_t
event' from 'kButton1' to 'kButton1Down'.
* gl/inc/TGLViewerEditor.h:
* gl/src/TGLViewerEditor.cxx:
Added widgets controlling 'fClearColor', 'fIgnoreSizesOnUpdate',
'fResetCamerasOnUpdate' and 'fResetCameraOnDoubleClick'; added
buttons for invoking 'UpdateScene()' and 'CameraHome()' methods.
* gl/src/TGLScene.cxx:
Removed code setting the glClearColor in 'Draw()'.

From Matevz Tadel:
1) Implementation of two-level (secondary) selection
Rendering objects can provide a new level of interactivity, for
example a TPointSet3D holding a set of clusters can attach a pointer
to original cluster to each point and receive notifications when a
specified cluster was clicked.
Secondary selection is activated by Control-Left clicking into the
GL window.
2) Improve control over camera-reset behaviour
Allow user to prevent camera reset on scene update and
double-click.
3) Improvements in TPointSet3D(GL)
Detailed ChangeLog
==================
* base/inc/TVirtualViewer3D.h:
Added virtual methods 'void ResetCameras(){}' and 'void
ResetCamerasAfterNextUpdate(){}'.
* gl/inc/TGLScene.h:
* gl/src/TGLScene.cxx:
Implemented two-level selection. It is enabled for next selection
pass by calling ActivateSecSelect().
DoSelect() does not change the selected object but only indicates
which object has been selected by setting new member
'TGLPhysicalShape *fSelectionResult'. Caller (TGLViewer) must call
new method 'void ApplySelection()' to actually change the selected
object to the last selection result.
Changed declaration of selection buffer from being a static varable
within DoSelect() to data-member. This allows post-processing of
selection records needed by two-level selection.
* gl/inc/TGLCamera.h:
* gl/inc/TGLOrthoCamera.h:
* gl/inc/TGLPerspectiveCamera.h:
* gl/src/TGLCamera.cxx:
* gl/src/TGLOrthoCamera.cxx:
* gl/src/TGLPerspectiveCamera.cxx:
Added Bool_t argument with default value to:
virtual void TGLCamera::Setup(const TGLBoundingBox & box, Bool_t
reset=kTRUE) = 0;
By setting it to false one can change camera parameters for new
scene bounding-box without repositioning the camera.
Added 'Bool_t checkSize' argument to OfInterest().
This is relevant for marker-classes which can have small
volume/length but are still visible as they are rendered in
pixel-coordinates. Value of this argument is needed in TGLScene
(DestroyPhysicals) and TGLViewer (AddObject). It is obtained by
calling virtual method TGLLogicalShape::IgnoreSizeForOfInterest().
This method returns false by defalut and is overriden in
TGLPolyMarker and TPointSet3DGL.
* gl/inc/TGLViewer.h:
* gl/src/TGLViewer.cxx:
Added controls for camera-reset behaviour.
Data-members: 'Bool_t fResetCamerasOnUpdate', 'Bool_t
fResetCamerasOnNextUpdate', 'Bool_t fResetCameraOnDoubleClick'.
Methods: 'ResetCameras()', 'ResetCamerasAfterNextUpdate()',
'ResetCurrentCamera()'.
Added an argument to 'void PostSceneBuildSetup(Bool_t resetCameras).
Added Bool_t return-value to RequestSelect(). It returns true if
result of the selection is different then fSelectedPhysical.
Added method ApplySelection() to interface with TGLScene
selection state. This is called from event-handling functions in
TGLViewer.
Added key-binding for 'Home': ResetCurrentCamera().
* gl/inc/TGLSAViewer.h:
* gl/src/TGLSAViewer.cxx:
Added description of new functionality to fgHelpText.
MSVC was complaining about fgHelpText being too long: I split it
into fgHelpText1 and fgHelpText2.
* gl/inc/TGLDrawFlags.h:
* gl/src/TGLDrawFlags.cxx:
Added members 'Bool_t fSelection' and 'Bool_t
fSecSelection' allowing passing of current selection state to
renderers. This is needed to allow different render-paths during
(secondary) selection.
We should consider passing TGLScene* and/or TGLViewer* down to
DirectDraw() of individual renderers.
* gl/src/TGLDrawable.cxx:
In ShouldCache() return false if secondary selection is in progress.
* gl/src/TGLPhysicalShape.cxx:
Handle new members in TGLDrawFlags.
* gl/inc/TGLLogicalShape.h:
* gl/src/TGLLogicalShape.cxx:
Added three new functions:
1) virtual Bool_t SupportsSecondarySelect() const { return kFALSE; }
This is called by TGLScene::DoSelect() to check is object that was
the result of primary selection supports secondary selection.
2) virtual void ProcessSelection(UInt_t* ptr, TGLViewer*, TGLScene*);
It is called back from TGLViewer after successful secondary
selection. As the object that does the rendering is the only one
that actually knows how the object sub-parts were named it has
to interpret the results.
Both of these should be overriden in classes that support
secondary selection, for example see TPointSet3DGL.
3) virtual Bool_t IgnoreSizeForOfInterest() const { return kFALSE; }
Signals to TGLScene and TGLViewer that volume/lenght of this
class' bounding box should not be considered when checking if
objects of this class are of interest to current camera.
* gl/inc/TGLObject.h:
* gl/src/TGLObject.cxx:
Changed second argument of function:
Bool_t SetModelCheckClass(TObject* obj, const Text_t* classname);
to 'TClass* cls'. This is much more efficient.
* g3d/inc/TPointSet3D.h:
* g3d/src/TPointSet3D.cxx:
Added support for per-point designations (one TObject* per point;
via casting it can be set to anything).
New virtual method 'void PointSelected(Int_t n)' that is called
back after successful secondary selection in TGLViewer (via
virtual TGLLogicalShape::ProcessSelection()).
* gl/inc/TPointSet3DGL.h:
* gl/src/TPointSet3DGL.cxx:
Added support for per-point selection. Point-sizes are taken into
account during selection (by modifying the projection
matrix).
Implemented 'virtual Bool_t TGLDrawable::ShouldCache()' to disable
caching when in primary selection (point-size improvements).
Cross-like marker types are now supported to some extent.
Improved structure of rendering code.
Override 'virtual Bool_t TGLLogicalShape::IgnoreSizeForOfInterest()'
to return true.
Multiply TAttMarker::GetMarkerSize() by 5 before applying.
* gl/inc/TGLPolyMarker.h:
Override 'virtual Bool_t TGLLogicalShape::IgnoreSizeForOfInterest()'
to return true.

Changes in TGLEditor, TGLColorEditor and TGLGeometryEditor
TGLSAViewer - GUI modified - old clip editor/guides
editor/lights - replaced by TGLViewerEditor.
GUI now works as in TPad's viewer - if you select
TGLViewer (shift + left click on a free scene space),
you - can see TGLViewerEditor,
if you select object in GL scene, you can see color
editor and geometry editor for this object.
TGLViewerEditor can be used in a pad and in a TGLSAFrame.

From Richard:
Implement manipulators (translate/scale/rotate) for all shapes in
viewer (previously only clip shapes could use them).
Behaviour:
i) Single selection in viewer - either a normal / clip shape or none.
Current manipulator is attached (and shown) when attached to selection.
ii) Normal viewer shapes are selected using Shift+Left Mouse button (and
have bounding box drawn).
iii) Clip shapes are shown/selected by checking 'Show/Edit' option on
the Scene/Clipping tab of the GUI.
iv) Any exisiting (normal/clip) selection is cleared when making new
choice.
v) (Transparent) clip shapes cannot be selected (picked) directly in the
viewer - normal shape override this.
Rotation properties of shapes are not reflected in GUI currently.

From Richard:
Fixes for perspective camera constraints. Camera has a level floor
formed from 2 of the 3 world axes - avoids tipping of horizon.
Previously only one combination was supported making it impossible to
navigate round some detectors naturally, or stand them on their 'feet'
supports.
'Projections' menu is now renamed 'Camera' and has three simple
perspective combinations:
Perspective (Floor XOZ) - default.
Perspective (Floor YOZ)
Perspective (Floor XOY)
in addition to 3 ortho combinations. Also updated help and default clips
to be more sensible with new default.

From Richard:
i) Add rotation manipulator.
ii) Allow direct manipulation of clipping plane - rotate/translate.
Cannot scale - makes no sense.
Note:
iii) Rotation interaction requires some improvement - difficult when
ring is almost parallel with eye line of camera.
iv) Still need to extend for all selected objects - requires some
internal rearrangement of TGLScene/TGLViewer

From Richard:
First implementation for interactive clipping, using OpenGL clip planes.
Initially we have plane & box - others later. See Help for description.
Known Bugs/Issues:
All in GUI:
i) Edit box takes keyboard focus and does not return to viewer pane when
clicked in. Hence all keys in viewer break - an existing general viewer
problem.
ii) Initial layout does not correctly hide the plane/box properties
panels, or scale for V side scroll bar.
Missing Features:
iii) CSG final pass and/or solid cappings.
iv) Can't rotate the box - need a TGLRotManip class soon.
v) Should be able to show and manipulate plane in similar fashion as
box.
vi) Trans/scale/rotate manipulators should be availible for any selected
object.

From Richard:
make TVirtualViewer TObject derv. so TPad can use without modifications.
Also removed last parts of TVirtualGL unrelated to context/draws so it
can be replaced with new TGLManager.
Added:
TGLSAViewer & TGLSAFrame - standalone viewer + GUI main frame.
TGLOutput for containing capture (pdf/eps output).
TX3DFrame (x3d mod) to avoid diamond TObject inheritance from GUI +
TVV3D interface
Removed: TViewerOpenGL
