================================================================================
27693

TEveCalo:
Set bounding box when calo data empty.

TEveCaloLegoGL:
TGLAxisPainter:
Draw axis title in TGLAxisPainter::PaintAxis().

--------------------------------------------------------------------------------
27694

Forget to check-in this file in revision 27693.

--------------------------------------------------------------------------------
27695

Don't draw frame and call TGLAxisPainter::Paint() if calo data empty.

--------------------------------------------------------------------------------
27699

Fix issues reported by valgrind.

--------------------------------------------------------------------------------
27758

Return viewer in TEveViewer::SpawnGLViewer and TEveViewer::SpawnGLEmbeddedViewer().

--------------------------------------------------------------------------------
27767

Unset event handler when destroying TGLWidget. This is important in case destruction of TGLWidget is called with timeout.

--------------------------------------------------------------------------------
27840

Add possibility to create different icon boxes in
TEveCompositeFrame. Use static function pointer fgIconBarCreator to change default behavior.

Remove oboslete function TEveCompositeFrame::ReplaceIconBox().

--------------------------------------------------------------------------------
7856

Bug fix: Get font size calculating projected axis length at the Z-title position.

--------------------------------------------------------------------------------
27857

Move to real world coordinates. Add line-set for test.

--------------------------------------------------------------------------------
27867

TGLViewer:
  Add function:
    void ResetInitGL()
  This is needed if GL-context is destroyed from outside.

  Call it from derived classes when creating and destroying GL-widget.

--------------------------------------------------------------------------------
27876

In line set add possibility to disable depth test, i.e. draw lines/markers in front.

--------------------------------------------------------------------------------
28013

Fix memory leak in TEveCalo2D.


--------------------------------------------------------------------------------
28048

In HandleCrossing() ignore grab and ungrab events. Several window managers produce them nowadays (fvwm2, x-on-mac, sawfish).

--------------------------------------------------------------------------------
28050

Simplify macro.

--------------------------------------------------------------------------------
28106

URL: http://root.cern.ch/viewcvs?rev=28106&root=root&view=rev
Log:
Add data-members and accessors for controlling brightness of front,
side and speulcar lights.

--------------------------------------------------------------------------------
28114

TGLPShapeObjEditor
==================
Remove obsolete data-members and enum entries.

TGLUtil
=======
New class TGLColor - using this will simplify color management in
TGLViewer and TGLRnrCtx.

TEveUtil
========
Simplify implementation of TEveUtil::ColorFromIdx() functions.

--------------------------------------------------------------------------------
28144

Add dtor for TGLColor.

--------------------------------------------------------------------------------
28161

URL: http://root.cern.ch/viewcvs?rev=28161&root=root&view=rev
Log:
Extend window management demo.

--------------------------------------------------------------------------------
28162

Add support several GL color-sets - each defines colors for background,
foreground, outline, markup and for outlines of selected and
highlighted objects.


GL/
===

TGLUtil   - add new class TGLColorSet.

TGLRnrCtx - add color-set stack.

TGLViewer - create two color-sets by default - for light and dark
background. These can be switched with the 'e' key now.

TGLScene  - decrease polgon-offset for outline-mode fill-pass from (1,
1) to (0.5, 0.5) which is sufficient.

Use/support color-set functionality in other modified classes.


EVE/
====

TEvePolygonSetProjectedGL - skip outline pass.

TEveProjectionAxesGL - skip outline pass and slightly widen the depth
range so that the text is visible in outline mode, where
polygon-offset is applied during the fill-pass.

--------------------------------------------------------------------------------
28168

Add support for a global GL color-set shared among several (all)
viewers.

TGLViewer - add static data-members and functions to handle global
color-set. Add methods that allow switching between global/private
color-sets for a given viewer.

TGLViewerEditor - Disable backgound-color widget when the viewer uses
global color-set.

TGLCameraOverlay - use foreground color for some markup rendering.

In two tutorials use the new API for setting of the background color.

--------------------------------------------------------------------------------
28187

Put back the old method for setting background color and mark it as deprecated.

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.
