History file for Ray Tracer category
---------------------------------------

15th November 2009  John Allison  (raytracer-V09-02-02)
- Formal tag to record fixing of bugzilla Problem 1072.
  o There is no change of source code.
  o This was actullay fixed in raytracer-V09-02-00, which is already accepted.

21st October 2009  John Allison  (raytracer-V09-02-01 coworks greps-V09-02-02)

  o Prevents warnings about hiding - calls G4VSceneHandler base class.

16 September 2009  John Allison  (raytracer-V09-02-00)
- Cosmetic adjustments and tagging.

19 August 2009 Laurent Garnier
- G4RayTracerViewer.cc, G4RayTracerXViewer.cc : Fix an bad use of fVP
  parameters [bugzilla Problem 1072]

18 August 2009 Laurent Garnier

  G4RTSimpleScanner and G4RTXScanner.

5th January 2007  John Allison  (raytracer-V08-02-00)
- Bug fix: use of window size hints.

17th November 2006  Joseph Perl  (raytracer-V08-01-02)
- Deprecate /vis/rayTracer/backgroundColour.
- Hasn't worked for some time anyway.
- Users are instead referred to /vis/viewer/set/background.

14th November 2006  John Allison  (raytracer-V08-01-01)
- Merged raytracer-V08-01-00-branch onto main branch.

11th November 2006  John Allison  (raytracer-V08-01-00-00)
- Followed change to G4Scene.

14th August 2006  John Allison  (raytracer-V08-01-00)

  robustness when under control of vis manager.

- G4RayTracerSceneHandler: Improved handling of dummy scene.
- G4TheRayTracer: Advance work for possible inclusion of
  anti-aliasing.  Currently no change of functionality.

11th January 2006  John Allison  (raytracer-V08-00-00)
- Reorganisation (needs visman-V08-00-02):
  o Allowed multiple ray tracers.
  o Separated out the original ray tracer into G4TheRayTracer, to be
    used by viewers.
  o Made G4RTMessenger a smart singleton that queries the vis manager
    for tracers.
  o Caused G4RayTracer to instantiate a default ray tracer if the user
    wants to use /vis/rayTracer commands without the benefit of the
    vis system (scene handlers and viewers).

4th December 2005  Makoto Asai (raytracer-V07-01-08)
- Correct initialization of G4RTTrackingAction and G4RTSteppingAction

- Implemented window positioning.

28th October 2005  Makoto Asai (raytracer-V07-01-05)
- Working tag for merging "envelope" into G4Region.
- This tag does not contain raytracer-V07-01-04 tag that might be
  already done by J. Allison but does not yet appear on this file.

13th October September 2005  John Allison (raytracer-V07-01-04)
(On branch raytracer-V07-01-01-branch; changes *not* merged into head -
need to cvs update -j raytracer-V07-01-02 -j raytracer-V07-01-01-branch.)
- Migrated to <sstream>.
- Default background black - can be changed by /vis/viewer/set/background.
- GNUmakefile: Removed temporary CPPFLAGS += -DG4VIS_BUILD_RAYTRACERX_DRIVER.

30th September 2005  Joseph Perl (raytracer-V07-01-03)
New tag to include change Makoto made an hour after V07-01-02 was tagged.
Change seems to just involve passing pWorld to material list where no argument was passed in previous version.

16th September 2005  John Allison (raytracer-V07-01-02)
(On branch raytracer-V07-01-01-branch; changes merged into head.)
- Bug fix (black holes): Made small epsilon push into world to ensure inside.

20th July 2005  John Allison (raytracer-V07-01-01)
- Protected RayTracerX by G4VIS macro.

17th July 2005  John Allison (raytracer-V07-01-00)
- Introduced RayTracerX.  RayTracerX opens an X window and builds up
  the picture, refining it gradually.  Already calculated pixels are
  not recalculated, so it is as efficient as a top-to-bottom raster
  scan.  It produces a jpeg file as well, just like RayTracer.

11th June 2004  Gabriele Cosmo  (raytracer-V06-01-00)
- Use global flag G4VIS_ALLOC_EXPORT to export extern symbols for DLLs.
  Modified GNUmakefile and rearranged usage of extern symbols in classes.

12th November 2003  Mark Donszelmann
- GNUmakefile: added Modeling/include directory to compile on Windows.

6th November 2003  John Allison  (raytracer-V05-02-04, vis-V05-02-03)
- GNUmakefile: rationalised.

4th October 2003  Gabriele Cosmo  (raytracer-V05-02-03)
- GNUmakefile:
  o added dependency to new module "geometry/navigation".
  o replaced "digits+hits" with "digits_hits".
- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".

25th September 2003  Hisaya Kurashige  (raytracer-V05-02-02)
- Modify GNUmakefile to use processes/cuts category 

18th September 2003  John Allison  (raytracer-V05-02-01, greps-V05-02-00)
- Introduced G4VRTScanner and its default concrete implementation,
  G4RTSimpleScanner.  It controls the shooting order of rays.
- Added new command /vis/rayTracer/backgroundColour.

4th August 2003  Makoto Asai  (raytracer-V05-02-00)
- Migrate to the changes with "Cuts per region"

11th December 2002  John Allison  (vis-V04-01-10)
- Fix for SUN-CC warnings: AddThis hides the virtual function...
- Fix memory leak in RayTracer.

11th November 2002  Hajime Yoshida and Minamimoto (raytracer-V04-00-01)
- Corrected G4RayTracer.cc devide-by-zero.

  perspective projection with *very* small field angle (perMillion).

22nd Nov 2001   Gabriele Cosmo  (raytracer-V03-02-02)
- G4RTJpegMaker.cc: added check on ISO compliance for binary mode on
  file streamsi, to allow compilation on non-ISO compilers.

13th Nov 2001   Hajime Yoshida and Minamimoto (raytracer-V03-02-01)
- Updation of G4RTJpegMaker.cc for Windows platform.

14th July 2001  John Allison  (raytracer-V03-02-00)
- Changed some arguments in G4RayTracer.hh from G4ThreeVector to const
  G4ThreeVector& to keep Sun compiler happy.

- Added protection for null viewer in G4RTSteppingAction.cc and
  G4RayTrajectory.cc.
- Corrected for zoom, etc., in G4RayTracerViewer.cc.

23rd February 2000  John Allison
- Added G4RayTracerSceneHandler and Viewer.
- Some modifications to other RayTracer routines for vis compliance.
- (Note: headAngle still not right - ray traced views are sometimes tipped.)

22nd February 2000  John Allison (raytracer-V01-00-01a)
- Added G4std:: in a few places to obtain ISO compliance.
- Change "char*" to "const char*" in G4OutBitStream::CopyByte(...).

22nd February 2000  Makoto Asai (raytracer-V01-00-01)

- Primary tag of sub-category

29th January 2000  Makoto Asai
- Introduction of G4RayTracer (visualization/RayTracer/...)
- Migration of G4RayTracer
