This file should be used by G4 developers and category coordinators

to briefly summarize all major modifications introduced in the code
|

and keep track of all category-tags.
|

It DOES NOT substitute the CVS log-message one should put at every
|

committal in the CVS repository !

|
|
- Limited the printing of warnings in
|
|
G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
|
|
|
|
14th August 2001 John Allison (vis-V03-02-11)
|
|
- Improved KernelVisitDecision.
|
|
- Fixed a few small bugs in multiple "stored" viewers, but see next item.
|
|
- There's an outstanding bug in OpenGL Stored. If there is more than
|
|
one viewer controlled by a scene handler, after a ClearStore on the
|
|
scene handler, e.g., with /vis/scene/notifyHandlers, the first
|
|
viewer to get refreshed should trigger the display list rebuild, but
|
|
the second need not. However, when the second viewer's turn comes,
|
|
the display lists are there, and are called, e.g.,
|
|
G4OpenGLStoredXViewer::DrawView calls
|
|
G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
|
|
nothing appears on the screen. To overcome this there is some
|
|
temporary code in G4VViewer::NeedKernelVisit which marks *all*
|
|
viewers to force a rebuild. To see the symptoms, comment out that
|
|
temporary code and issue these commands:
|
|
/vis/verbose c
|
|
/control/verbose 2
|
|
/vis/scene/create
|
|
/vis/scene/add/volume
|
|
/vis/sceneHandler/create OGLSX
|
|
/vis/viewer/create ! ! 1
|
|
/run/beamOn
|
|
/vis/viewer/create ! ! 1
|
|
/vis/viewer/select viewer-0
|
|
/vis/viewer/viewpointThetaPhi 20 20
|
|
/vis/viewer/select viewer-1
|
|
/vis/viewer/viewpointThetaPhi 40 40
|
|
/vis/viewer/set/style surface
|
|
/vis/viewer/refresh
|
|
/vis/viewer/select viewer-0
|
|
/vis/viewer/refresh
|
|
/vis/viewer/select viewer-1
|
|
/vis/viewer/set/style wireframe
|
|
/vis/scene/notifyHandlers
|
|
You may have to do this too:
|
|
/vis/viewer/select viewer-0
|
|
/vis/scene/notifyHandlers
|
|
One of the viewers is empty. Curious!!

9th August 2001 John Allison (vis-V03-02-10-00)
|
|
- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
|
|
- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
|
|
invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
|
|
picked up by inheritance anyway.
|
|
- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
|
|
- Corrected order of calling base class functions in
|
|
G4OpenGLStoredSceneHandler::Begin/EndModeling.
|
|
|
|
24th July 2001 John Allison (vis-V03-02-06)
|
|
- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
|
|
|
|
14th July 2001 John Allison (opengl-V03-02-00)
|
|
- Fixed crash in optimised mode: added Initialise() to viewers so
|
|
that windows are opened after viewers are fully constructed.
|
|
|
|
2nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
|
|
- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
|
|
|
|
7th March 2001 John Allison
|
|
- Changed char* to const char* in many places and that gave problems in
|
|
calls to Xt and Xm. Hope all's OK. Differences:
|
|
cvs diff -r vis-V03-00-06 vis-V03-00-07
|
|
|
|
25th January 2001 John Allison (opengl-V03-00-00)
|
|
- Implemented running re-calculation of up-vector in the case of "object
|
|
rotation" (lights move with camera) to prevent "flipping" of view when
|
|
camera passes through up-vector. Note that the default is "camera
|
|
rotation" (lights do not move with camera, i.e., remain fixed relative
|
|
to object) so the default is that this "flipping" can happen. To set
|
|
"object rotation" (lights move with camera) use
|
|
/vis/lights/move_with_camera true (soon to be
|
|
/vis/viewer/set/lights move-with-camera) or click "Object" radio button
|
|
on Rotation Panel in OpenGLXm mode.
|
|
- Changed some objects to references for efficiency. E.g.:
|
|
const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
|
|
|
|
22nd May 2000 John Allison (opengl-V01-01-00)
|
|
- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
|
|
by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
|
|
static XVisualInfo* vi_single_buffer;
|
|
static XVisualInfo* vi_double_buffer;
|
|
- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
|
|
G4OpenGLXViewer.
|
|
- Protected double deletion of window in destructors of G4OpenGLXmViewer
|
|
and G4OpenGLXViewer (Guy Barrand).
|
|
- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
|
|
- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
|
|
constructors.
