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.

New Revision: 33431

URL: http://root.cern.ch/viewvc?rev=33431&root=root&view=rev
Log:
Add full support for handling of projected tracks in topologically non-trivial
projections. Use the following setters in TEveTrackPropagator:
   void   SetProjTrackBreaking(UChar_t x);
   void   SetRnrPTBMarkers(Bool_t x);
   TMarker& RefPTBAtt() { return fPTBAtt; }
to tune the behaviour. The following modes are supported:
   enum EProjTrackBreaking_e {
     kPTB_Break,            // break tracks
     kPTB_UseFirstPointPos, // use first track-point half-space
     kPTB_UseLastPointPos   // use last track-point half-space
   };

SetRnrPTBMarkers(Bool_t x) allows to enable drawing of a marker with
attributes RefPTBAtt() at break-points.

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.
}

When initializing TGLClipPlane for the first time, place it in the
center of the scene's bounding-box.
Before that, plane was always positioned at (0,0,0) which lead to
unexpected behaviour when scene was not centered at the origin.

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.

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:
Cleanup of shape code:

i) Remaining minodr code from TGLSceneObject moved to TGLLogicalShape or
derv. shape classes.

ii) Remove obsolete TGLSceneObject class.

iii) Move shape classes (TGLFaceSet etc) to own .h/.cxx + now derv. from
TGLogicalShape directly

Plus other minor tidying up.

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.

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.
