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.

Introduce virtual function:
void TGLViewerBase::SetupClipObject()
that is called half-way through the TGLViewer::PreRender() -- when
overall bounding box is known but the individual scene visibility has
not been determined yet. Thus scene visibility can be properly
determined if the clipping object changes due to a large change in
overall bounding box.
This is overriden in TGLViewer where all clipping objects (plane and
box) need to be modified.
Move auto-clip-update flag from TGLViewer to TGLClipSet so that the
TGLClipSetEditor can modify it.

Add virtual function TGLClip::Setup(const TGLVector3&, const TGLVector3&)
and implement it for plane and box clipping objects.
void TGLClipPlane::Setup(const TGLVector3& point, const TGLVector3& normal)
{
// Setup the clipping plane by point and normal.
// Length of the normal determines the size of the plane drawn in
// GL viewer. The normal points into the direction of visible half-plane.
//
// This only makes sense if you disable auto-update of the
// clip-object:
// gl_viewer->SetClipAutoUpdate(kFALSE).
// After calling this also call gl_viewer->RefreshPadEditor(gl_viewer)
// and gl_viewer->RequestDraw().
}
void TGLClipBox::Setup(const TGLVector3& min_point, const TGLVector3& max_point)
{
// Setup the clip box with min/max points directly.
//
// Same comments as for the TGLClipPlane apply.
}

Allow clipping object to be fixed by user - until now it was updated
on every redraw.
- TGLClip: Add 'Bool_t fValid' data-member and accessor methods:
Bool_t IsValid() const;
void Invalidate();
Honour this in concrete clip classes.
- TGLClipSet: Add methods:
void SetupCurrentClip(const TGLBoundingBox& sceneBBox);
void SetupCurrentClipIfInvalid(const TGLBoundingBox& sceneBBox);
void InvalidateClips();
void InvalidateCurrentClip();
Add data-member 'TGLBoundingBox fLastBBox' to cache the last scene
bounding box that was used to resize the clip-set.
- TGLViewer: Add 'Bool_t fClipAutoUpdate' data-member and accessors:
Bool_t GetClipAutoUpdate() const;
void SetClipAutoUpdate(Bool_t x);
Use this member to steer clip-object updates.
-TGLPlane: Move many unnecessarily inline functions to cxx file.

TGLClip
=======
In TGLClipSet::SetClipState() negate also the distance from plane.
There was state mismatch between TGLClipPlane and TGLClipSetEditor.
Other files
===========
Consistent documentation-markup and white-space.

From Matev and Timur:
Timur:
1. Allow unique identification of shared GL contexts via
TGLContextIdentity class.
Matevz:
1. Improved overlay selection handling.
2. Perform GL context check before rendering, possibly invalidating
registered display-lists.
3. Minimize updates for window expose and resize events.

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 Richard:
Code cleanup.
This patch is the last contribution from Richard to the project.
Many thanks to him for his work with the GL viewer and the impressive
improvements in the past few months.

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.

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

Original Path:

File length: 2134 byte(s)
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.
