Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.

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:
 Second part of general tidy for coding conventions violations -
mainly commenting. Code under my name should be clear now.

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

Revision 12892 - (view) (download) (as text) (annotate) - [select for diffs]
Added Mon Oct 3 15:19:35 2005 UTC (9 years, 3 months ago) by brun

File length: 1348 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.
