Move enums away from global namespace:
- EOverlap is now in namespace Rgl;
- EClipType is now in class TGLClip;
- EPosition and EManipType were not used and have been removed.
EGLCoordType and EGLPlotType are left in top-level. In these two enums all
names begin with kGL so there is less chance for collision.

Implement arc-ball camera rotation. Use the 'a' key to switch between the
standard (up-direction fixed) and arc-ball rotation modes.
* TGLCamera
Add functions RotateArcBall() and RotateArcBallRad().
Add member 'Bool_t fWasArBalled'. Check its state in standard Rotate
function and fix up direction if needed.
* TGLOrthoCamera, TGLPerspectiveCamera
Use combined view matrix's third vector as the up direction.
* TGLEventHandler
Add arc-ball state variable and key-handling.
Add logic for calling std vs arc-ball camera rotate function.
* TGLSAViewer
Document arc-ball key binding in help text.

Optimizations based on Druid callgrind dump sent by Manqi.
* TGLBoundingBox:
Use TGLVertex3[8] instead of std::vector<> for member that always
has 8 elements. Caused pointless allocations and fragmentation.
* TGLScene:
In CalcBoundingBox() avoid creating a bounding box temporary in a
loop over all elements -- use const& instead.
* TGLCamera:
Fix for changes in TGLBoundingBox.

gl/:
----
- extensions for transparency handling in TGLUtil;
- allow disabling of internal viewer selection;
- allow fixing of default camera center;
- fix global light placement -- it was only correct for XoZ floor or
when scene center was at the origin.
eve/:
-----
- propagation of main transparency to projected replicas and to
compound members;
- when projecting TEveStraightLineSet in RhoZ, break lines crossing
the separating plane (required change of internal representation);
- anti-flickering support for TEveBoxSet;
- proper multiple-selection handling in TEveCalo classes;
- small new features, bug fixes in TEveCalo classes.

Date: Mon May 31 13:41:54 2010
New Revision: 33666
URL: http://root.cern.ch/viewvc?rev=33666&root=root&view=rev
Log:
Propagate main transparency the same way as main color is propagated:
- from projectables to projecteds;
- in CopyVizParams();
- in TEveCompound to children depending on the following CSC bit settings:
kCSCBApplyMainTransparencyToAllChildren
kCSCBApplyMainTransparencyToMatchingChildren
In TEveElementList add member 'Bool_t fDoTransparency' (analoguous to
fDoColor).

Date: Mon May 31 15:44:20 2010
New Revision: 33668
URL: http://root.cern.ch/viewvc?rev=33668&root=root&view=rev
Log:
In TEveelement introduce Bool_t members fCanEditMainColor and
fCanEditMainTransparency. The corresponding base-class functions now
return the value of these data members.
In most sub-classes that require editng of main color and transparency
it was now enough to set these data-members to kTRUE in constructors.
Further, this allows per object setting of color / transparency
editability via:
void SetEditMainColor(Bool_t);
void SetEditMainTransparency(Bool_t);

Small fixes for track rendering.
TEveTrack
- Implement virtual ComputeBBox() to include path-mark positions in

version.
TPointSet3D

* TGLBoundingBox:
- IsEmpty() was using Volume() to decide whether the box is empty.
This caused scenes with 2d objects only to be ignored during scene
selection in TGLViewerBase::PreRender().
* TGLCamera:
- Use TGLBoundingBox::Diagonal() instead of Volume() also for
calculation of OfInterest().
* EVE classes:
- remove workarounds for the TGLBoundingBox bug that accumulated
over time.

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.

From Matevz:
I made another mistake in gl/: in TGLCamera::OfInterest() i named the argument 'checkSize' instead of 'ignoreSize'.
This patch removes this inconsistency and fixes behaviour for polymarkers whoose (point-count is > 1) && (volume of bounding-box is small but not zero).

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.

From Timur:
"I've investigated the problem reported by Andrei concerning missing
volumes when drawing large geometries.
what was wrong -
two boxes, one has very big sizes, the second is very small. With gl
viewer you can see only the big one. The small box is rejected by
TGLCamera::OfInterest - it seems to me, that Richard has selected some
numbers by guess-work. This patch contains a fix (another
numbers selected by guess-work by me:))."

From Richard:
Fixes for wireframe and outline drawing:
i) Both very much slower (up to 10x) than normal filled polygons -
incorrectly calling DirectDraw() bypassing the DL caching.
ii) Outline style did expensive repeated GL state swaps for every
physical shape draw.
iii) Only TGLFaceSet supported outline draw style.
Now:
i) Wireframe roughly same speed (or faster) than filled (~10x faster)
ii) Outline takes ~ filled polygons + wireframe times - as would expect
(about 5x faster).
iii) All shapes support outline style.
Exatct speed gain hardware dependent - but even software GL faster.
Also tidied up draw style code - created new TGLDrawFlags class to wrap
style + LOD hint into.

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.

ii) Shallow - when ring plane is at shaloow angle to eye (very tight
ellipse). Here just use pixel delta (drag) on viewport along ring plane.
To show difference draw followed ring line for i) and drag direction

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.

Update to GL viewer to:
i) Retain modifications/section of physical shapes across scene
rebuilds.
ii) Be a bit smarter about rebuilds:
Detect if all physicals accepted into scene - never need to rebuild in
these cases.
Only destroy physicals no longer of interest to camera.
Imporves times a bit - more work on this required to remove stalls in
viewer interaction.

From Richard Maunder:
Fixes for camera limits - greater ranges +
Right Mouse: Dolly Camera (Move In/Out) with side/side motion (as
before). Also j/k keys control.
Mouse Wheel: Zoom Camera - adjust field of view of 'lens'. As expected
this can introduce noticable distortion at wide angles.
Combination of two gives a very large 'zoom' range for the camera
sufficient for current detectors.
Additionally modifiers adjusts the sensitvity of the interactions,
making easier to tune in on a certain part:
Shift: x 10
Ctrl: x 0.1
Shift+Ctrl: x 0.01
NB Modifier must go down after mouse button for shift to avoid
[Under Win32 the modifiers do not work with mouse wheel (Zoom) as
TGEvent does not contain them for some reason. Will log a bug for this
to be looked into]
Also:
i) Added 'debug' mode for viewer (toggle with 'd' key) which draws out
camera interest, frustum basis, scene boxes etc in various colors. In
debug mode rebuilds only done when forced with space key strike.
ii) Fixes lost objects in some scene rebuilds.

From Richard Maunder:
Major changes to GL viewer to support:
i) Logical/Physical shape pairings
ii) Level of detail (LOD) scheme (TGLSphere only using at present)
iii) Common display list cache
iv) Scene rebuilds for large geometries
v) Some basic interactivity improvements - draw timeouts, drop low LOD
shapes etc
vi) New camara interactions:
Left Mouse: Rotate
Middle Mouse: Truck (pan parallel to camera film plane)
Right Mouse: Side-side drag dolly/zoom
Double click any button to reset the camera.
The previous pan with arrow keys, and zoom on mouse wheel are still
supported.
Camera interaction is default in viewer. These extra camera modes mean
there are not enough mouse buttons for previous right context/select.
To select / invoke context menu use Shift+Left Button and Shift+Right
Button respectively.

From Timur Pocheptsov
What's added:
1. Several modes :
"Navigation" - our standard rotation (context menu added(*))
"Picking" - user can select object and move it (**)
"Material editor" - not implemented, now it simply allows to
make objects transparent.
2. Several views :
Perspective view and three orthogonal projections
