347 | than one primitive were drawn between BeginPrimitives and |
---|
348 | EndPrimitives, it would finish up all in one display list, colour |
---|
349 | commands included. Rationalises and fixes a rare bug in the |
---|
350 | Display-by-Time feature - see August 2006.) |
---|
351 | o Added AddPrimitive(const G4Polymarker&) so that it is treated as |
---|
352 | one primoitive to fit with the above re-organisation. |
---|
353 | - Implemented picking for OGLIX. |
---|
354 | |
---|
355 | 25th March 2007 John Allison (opengl-V08-02-03) |
---|
356 | - Fix compiler warnings. |
---|
357 | |
---|
358 | 8th February 2007 John Allison (opengl-V08-02-02) |
---|
359 | - Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.) |
---|
360 | - G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched |
---|
361 | .but not switched back. Not serious, because context was always set |
---|
362 | before normal drawing.) |
---|
363 | |
---|
364 | 9th January 2007 John Allison (opengl-V08-02-01) |
---|
365 | - Implemented bitmap markers for MarkerSizeType == screen. (The old |
---|
366 | polygon implementation remains for MarkerSizeType == world.) |
---|
367 | - Added G4OpenGLBitMapStore to assist the above. |
---|
368 | - G4OpenGLXViewer::CreateGLXContext: |
---|
369 | o Bug fix: Added missing break in colormap lookup routine. |
---|
370 | |
---|
371 | 5th January 2007 John Allison (opengl-V08-02-00) |
---|
372 | - G4OpenGLSceneHandler.cc: |
---|
373 | o Followed change of signature of GetLineWidth in visman-V08-02-00. |
---|
374 | o Minor efficiency improvements. |
---|
375 | |
---|
376 | 21st November 2006 John Allison (opengl-V08-01-09) |
---|
377 | - Fixed compiler warnings. |
---|
378 | |
---|
379 | 1st November 2006 John Allison (opengl-V08-01-08) |
---|
380 | - Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command |
---|
381 | actually initiates a print, rather than set a flag for printing. |
---|
382 | |
---|
383 | 24th October 2006 John Allison (opengl-V08-01-07) |
---|
384 | - G4OpenGLStoredViewer.cc: Calculate light front horizon properly. |
---|
385 | - G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh. |
---|
386 | |
---|
387 | 19th September 2006 John Allison (opengl-V08-01-06) |
---|
388 | - Added time origin for light front. |
---|
389 | - Added /vis/ogl/set/transparency. |
---|
390 | - G4OpenGLStoredViewer.cc: Bug fix in time range acceptance. |
---|
391 | |
---|
392 | 4th September 2006 John Allison (opengl-V08-01-05) |
---|
393 | - Implement cutaways. |
---|
394 | - Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all |
---|
395 | primitives (see detector being drawn). |
---|
396 | - /vis/oglx/set/printEPS: change parameter default to true. |
---|
397 | |
---|
398 | 30th August 2006 John Allison (opengl-V08-01-04) |
---|
399 | - G4OpenGLSceneHandler: |
---|
400 | o Implemented line width. |
---|
401 | o Switched off back face culling when clipping so that the inside of |
---|
402 | volumes can be seen. |
---|
403 | o Added CreateSection/CutawayPolyhedron to exploit generic |
---|
404 | sectioning (DCUT) and cutaways. Currently not activated due to |
---|
405 | instabilities in BooleanProcessor. Local sectioning still active |
---|
406 | but broken (at least on Mac) due to apparent change in effect of |
---|
407 | clipping planes (polyhedron edges not reconstructed). |
---|
408 | o Rationalised calculation of marker size. |
---|
409 | - G4OpenGLStoredSceneHandler: |
---|
410 | o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers). |
---|
411 | o Pick up time range from G4VisAttributes. |
---|
412 | - G4OpenGLViewer(Messenger): |
---|
413 | o Added position and colour to /vis/ogl/set/displayHeadTime. |
---|
414 | o Added /vis/ogl/set/displayLightFront. |
---|
415 | - G4OpenGLStoredViewer.cc: |
---|
416 | o Rationalised CompareForKernelVisit. (Local sectioning still active.) |
---|
417 | o Added position and colour to DisplayHeadTime. |
---|
418 | o Added DisplayLightFront. |
---|
419 | |
---|
420 | 16th August 2006 John Allison (opengl-V08-01-03) |
---|
421 | - Corrected Solaris compilation error. |
---|
422 | - Added /vis/ogl/set/fade and displayHeadTime. |
---|
423 | |
---|
424 | 14th August 2006 John Allison (opengl-V08-01-02) |
---|
425 | - Needs visman-V08-01-02. |
---|
426 | - G4OpenGLStored: Implemented display-by-time. Only available in |
---|
427 | stored mode at present. Only implemented for circle, square, |
---|
428 | polyline and polymarker at present, enough for currently available |
---|
429 | trajectory models. Time is communicated via G4AttValues. |
---|
430 | - Added G4OpenGLViewerMessenger. |
---|
431 | - Added /vis/ogl/set/startTime and endTime of displayed objects. |
---|
432 | - All factories: Instantiated G4OpenGLViewerMessenger. |
---|
433 | - G4OpenGLViewer: Added fStart/EndTime. |
---|
434 | - G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in |
---|
435 | spewPrimitiveEPS and spewSortedFeedback. |
---|
436 | |
---|
437 | 17th July John Allison (opengl-V08-01-01) |
---|
438 | - Added /vis/oglx/set/printEPS (prints eps file on every update). |
---|
439 | |
---|
440 | 3rd July 2006 John Allison (opengl-V08-01-00) |
---|
441 | - Elimination of redundant variable doublebuffer and implementation of |
---|
442 | FinishView in all viewers. |
---|
443 | |
---|
444 | 30th May 2006 Joseph Perl (opengl-V08-00-08) |
---|
445 | - G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that |
---|
446 | variable seems to have random behavior and should be assumed false for |
---|
447 | this viewer. |
---|
448 | |
---|
449 | 29th May 2006 Joseph Perl (opengl-V08-00-07) |
---|
450 | - G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer: |
---|
451 | Removed common FinishView and instead made separate FinishView for the two different |
---|
452 | versions of this viewer since each wants a different buffer swapping behaviour. |
---|
453 | |
---|
454 | 12th May 2006 John Allison (opengl-V08-00-06) |
---|
455 | - G4OpenGLWin32Viewer: Fixed buffer swapping behaviour. |
---|
456 | |
---|
457 | 28th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14) |
---|
458 | - G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when |
---|
459 | recomputing transients. |
---|
460 | |
---|
461 | 24th April 2006 John Allison (opengl-V08-00-04) |
---|
462 | - Fixed compilation problem on Windows. |
---|
463 | |
---|
464 | 19th April 2006 John Allison (opengl-V08-00-03) |
---|
465 | - G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and |
---|
466 | G4OpenGLImmediateSceneHandler: |
---|
467 | o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and |
---|
468 | greps-V08-00-02). |
---|
469 | o Migrated to direct access to G4PhysicalVolumeModel. |
---|
470 | - G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing |
---|
471 | of display lists in DrawView. |
---|
472 | |
---|
473 | 14th March 2006 John Allison (opengl-V08-00-02) |
---|
474 | - Refined display list building and re-drawing algorithm. |
---|
475 | o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE. |
---|
476 | o Avoided unnecessary re-execution in DrawView (X, Xm and Win32). |
---|
477 | - G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list |
---|
478 | re-use algorithm. In test19 with global culling off, numbers of |
---|
479 | display lists used are: |
---|
480 | o 191 No re-use: |
---|
481 | o 73 Before this change: re-use except replicas (includes parameterised). |
---|
482 | o 33 After this change: re-use except parameterised and replicas in radius. |
---|
483 | |
---|
484 | 26th January 2006 John Allison (opengl-V08-00-01) |
---|
485 | - Coworks with visman-V08-00-04 (removed fModified). |
---|
486 | - Removed references to fModified. |
---|
487 | - Tidying: Removed unnecessary ClearView. |
---|
488 | - G4OpenGLSceneHandler.cc: Added some (commented out) code for |
---|
489 | possible future implementation of 2D drawing. |
---|
490 | - G4OpenGLXViewer.cc: Improved exception printing. |
---|
491 | |
---|
492 | 11th January 2006 John Allison (opengl-V08-00-00) |
---|
493 | - Improved efficiency: all DrawView's: |
---|
494 | o Don't call ClearView. |
---|
495 | o Set flag so SetView will not be called in ProcessView. |
---|
496 | o Leave background colour to ClearView. |
---|
497 | - Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore. |
---|
498 | - G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager |
---|
499 | for current viewer. |
---|
500 | |
---|
501 | 24th November 2005 John Allison (opengl-V07-01-09) |
---|
502 | - Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER. |
---|
503 | |
---|
504 | 22nd November 2005 John Allison (opengl-V07-01-08) |
---|
505 | - Added G4OpenGLXmViewerMessenger. |
---|
506 | - Corrected text position. |
---|
507 | - Made depth test for polyhedron GL_LEQUAL (slightly dominant). |
---|
508 | |
---|
509 | 17th November 2005 Gabriele Cosmo |
---|
510 | - Fixed settings of background style for WIN32 viewers. |
---|
511 | |
---|
512 | 13th November 2005 John Allison (opengl-V07-01-07) |
---|
513 | - Implemented X-Window-style geometry hints in G4OpenGLXViewer. |
---|
514 | |
---|
515 | 13th October 2005 John Allison (opengl-V07-01-06) |
---|
516 | - Allowed any colour background. |
---|
517 | - Implemented non-uniform scaling. |
---|
518 | - Migration to <sstream>. |
---|
519 | |
---|
520 | 29th September 2005 John Allison (opengl-V07-01-05) |
---|
521 | - Added G4OpenGLViewerDataStore to facilitate access of viewer data by |
---|
522 | scene handler. |
---|
523 | - Re-implemented transparency button in OpenGLXm. |
---|
524 | |
---|
525 | 13th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02) |
---|
526 | - Implemented white background for all OGL viewers. |
---|
527 | - G4OpenGLSceneHandler.cc: |
---|
528 | o Fixed hidden line removal (bug introduced in opengl-V07-01-02). |
---|
529 | o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines. |
---|
530 | o Corrected GetTextColour(text). |
---|
531 | o Corrected GetColour(polyhedron). |
---|
532 | |
---|
533 | 5th September 2005 John Allison (opengl-V07-01-03) |
---|
534 | - Bug fix: stored transparent objects were being lost. |
---|
535 | |
---|
536 | 2nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01) |
---|
537 | - Bug fix: edgeflags problem introduced with smooth shading in |
---|
538 | opengl-V07-01-00. |
---|
539 | - Implementation of a "better algorithm" for the rendering of |
---|
540 | transparent polyhedron objects. It renders all opaque objects |
---|
541 | first, then renders the transparent objects with the depth buffer in |
---|
542 | read-only mode (see OpenGL Programming Guide). It uses the new |
---|
543 | facility in G4VSceneHandler::ProcessScene for an optional second pass |
---|
544 | of the run-duration models in the scene. Note this algorithm is |
---|
545 | still only an approximation. It will still give the wrong blended |
---|
546 | colour if two transparent objects are rendered front first. For |
---|
547 | nested transparent objects, this is unfortunate, because |
---|
548 | G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy |
---|
549 | in such a way that mothers come first. Also, there is no guaranteed |
---|
550 | relationship between the order of rendering and the depth of two |
---|
551 | transparent objects if they are at the same level or in different |
---|
552 | branches of the hierarchy. Still, the only error will be an |
---|
553 | incorrect colour - the objects will still give the appearance of |
---|
554 | transparency, so it's a pretty good algorithm. (An even better |
---|
555 | algorithm would be to attempt to render the facets in depth order, |
---|
556 | deepest first. But how do you calculate the depth - centre of area, |
---|
557 | deepest corner? One can still imagine pathalogical cases that would |
---|
558 | sometimes give the wrong colour. Also, for stored mode, the order |
---|
559 | is fixed in a display list so when the user rotates the view, one |
---|
560 | would lose the depth ordering. I think we have to accept that |
---|
561 | blending in OpenGL is only ever an approximation. For accurate |
---|
562 | blending, use RayTracer.) |
---|
563 | |
---|
564 | 28th August 2005 John Allison (opengl-V07-01-01) |
---|
565 | - Half-way implementation of rendering of transparent polyhedron |
---|
566 | objects. In this implementation, no account is taken of the order |
---|
567 | of rendering. Transparent objects are rendered with depth testing |
---|
568 | off so that objects behind can still be seen. But this means that |
---|
569 | opaque objects in front do not obscure them - and they jolly well |
---|
570 | should! A better algorithm is to render all opaque objects first, |
---|
571 | then render the transparent objects with the depth buffer in |
---|
572 | read-only mode (see OpenGL Programming Guide). This is going to |
---|
573 | take a little more thought - see opengl-V07-01-02. |
---|
574 | |
---|
575 | 20th July 2005 John Allison (opengl-V07-01-00) |
---|
576 | - Introduced smooth shading, taking advantage of hitherto un-noticed |
---|
577 | feature of HepPolyhedron::GetNextFacet that calculates the normals |
---|
578 | at each vertex so that curved surfaces are rendered more |
---|
579 | realistically (Gouraud shading). |
---|
580 | - G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's. |
---|
581 | - G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes |
---|
582 | the default window size. It used to be 400x400, hardcoded in |
---|
583 | G4OpenGLXmViewer.cc, but now it picks up the |
---|
584 | G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600. |
---|
585 | The user may change it on the command line, e.g: |
---|
586 | /vis/open OGLSXm 500 |
---|
587 | or |
---|
588 | /vis/viewer/create ! ! 500 |
---|
589 | |
---|
590 | 30th May 2005 John Allison (opengl-V07-00-03) |
---|
591 | - Fixed compilation problem in OpenGL on SUN. (Replaced multimap by |
---|
592 | map of vectors in G4OpenGLFontBaseStore.) |
---|
593 | |
---|
594 | 4th May 2005 John Allison (opengl-V07-00-02) |
---|
595 | - Restored sequence Set/Clear/DrawView in ClearTransientStore. (It |
---|
596 | was taken out to prevent recursive calling, but that seems to be OK, |
---|
597 | and it is needed to implement refresh at end of event/run.) |
---|
598 | |
---|
599 | 22nd April 2005 John Allison (opengl-V07-00-01) |
---|
600 | - Rationalised work of opengl-V07-00-00. Functionality unchanged. |
---|
601 | o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}. |
---|
602 | o In all concrete viewers, added call to CreateFontLists(). |
---|
603 | o Moved font code for X to G4OpenGLXViewer::CreateFontLists(). |
---|
604 | o There is no longer a need to implement in the XmViewer, since it |
---|
605 | now inherits. Thus the font code now only appears once for X. |
---|
606 | o Awaiting implementation for WIN32. |
---|
607 | |
---|
608 | 17th April 2005 John Allison (opengl-V07-00-00) |
---|
609 | - Based on vis-V07-00-13. |
---|
610 | - Implemented text for X-Windows viewers. Uses glXUseXFont, which |
---|
611 | creates display lists for nominated fonts. Simple-minded scheme in |
---|
612 | which each viewer creates its own font display lists for a variety |
---|
613 | of sizes, which are accessed by the scene handler through a new |
---|
614 | class, G4OpenGLFontBaseStore. Affected methods: |
---|
615 | G4OpenGLXViewer::CreateMainWindow() |
---|
616 | G4OpenGLXmViewer::CreateMainWindow() |
---|
617 | G4OpenGLSceneHandler::AddPrimitive (const G4Text& text) |
---|
618 | |
---|
619 | 18th November 2004 John Allison (opengl-V06-02-07) |
---|
620 | - Removed redundant fLastVP from G4OpenGLStoredSceneHandler. |
---|
621 | |
---|
622 | 15th November 2004 Guy Barrand |
---|
623 | - G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient |
---|
624 | to see trajectories (for example with N03). Correct so that |
---|
625 | ShowView do a FinishView that does : glFlush, wglSwapBuffer |
---|
626 | and empty the Windows message queue. |
---|
627 | |
---|
628 | 22nd September 2004 John Allison (opengl-V06-02-06) |
---|
629 | - doxygen output to tmp area. |
---|
630 | - Trap non-regular polyhedrons. |
---|
631 | |
---|
632 | 13th September 2004 Gabriele Cosmo (opengl-V06-02-05) |
---|
633 | - G4OpenGLTransform3D.cc: simplified implementation for GetMatrix() |
---|
634 | to allow for porting on CLHEP-1.9.X series. |
---|
635 | |
---|
636 | 23rd July 2004 John Allison |
---|
637 | - Draws auxiliary edges if required. |
---|
638 | - Added auxiliary edge button. |
---|
639 | |
---|
640 | 16th July 2004 John Allison (opengl-V06-02-04) |
---|
641 | - Refinements to hidden line, hidden surface removal. |
---|
642 | |
---|
643 | 14th July 2004 John Allison (opengl-V06-02-03) |
---|
644 | - Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc. |
---|
645 | |
---|
646 | 13th July 2004 John Allison (opengl-V06-02-02) |
---|
647 | - Hidden line *and* hidden surface removal now works. |
---|
648 | |
---|
649 | 9th July 2004 John Allison (opengl-V06-02-01) |
---|
650 | - Fixed long-standing problem with hidden line removal. |
---|
651 | - Improved messages on failure to get visual. |
---|
652 | - Added GLX_STENCIL_SIZE explicit request to visual attributes - most |
---|
653 | systems provided by default anyway, so no effect. |
---|
654 | |
---|
655 | 1st July 2004 John Allison (opengl-V06-02-00) |
---|
656 | - Rationalised G4OpenGLSceneHandler ready for hidden line removal. |
---|
657 | - Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control. |
---|
658 | |
---|
659 | 18th June 2004 Gunter Folger (geant4-06-02) |
---|
660 | 9th June 2004 Gabriele Cosmo (vis-V06-01-03) |
---|
661 | 7th June 2004 Gabriele Cosmo (vis-V06-01-02) |
---|
662 | - GNUmakefile and disclaimer changes - see visualization/History. |
---|
663 | |
---|
664 | 9th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00) |
---|
665 | - Tagged OpenGL as below. Joint with interfaces-V06-01-00. |
---|
666 | |
---|
667 | 7th April 2004 Guy Barrand |
---|
668 | - visualization/OpenGL/* : use the G4OpenGL.hh file. |
---|
669 | - Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate |
---|
670 | the include of gl/gl.h and gl/glu.h that may be platform dependant. |
---|
671 | It permits to rm some #ifdef WIN32 spread in the code. It opens also |
---|
672 | the way to the usage of the Apple OpenGL on a Mac. |
---|
673 | |
---|
674 | 17th February 2004 John Allison (opengl-V06-00-00) |
---|
675 | - Fixed bug #581: wrong order of statements in |
---|
676 | G4OpenGLXViewer::~G4OpenGLXViewer (see bug report). |
---|
677 | |
---|
678 | 4th October 2003 Gabriele Cosmo (vis-V05-02-01) |
---|

---|
706 | - Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER. |
---|
707 | - Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply |
---|
708 | call default but there as a marker and encourager. |
---|
709 | - Added tracking and digits+hits/hits to GNUmakefile. |
---|
710 | |
---|
711 | 16th October 2002 John Allison (opengl-V04-01-01) |
---|
712 | - Fix for WIN32. Now compiles but viewer not implemented. |
---|
713 | |
---|
714 | 24th June 2002 John Allison (opengl-V04-01-00) |
---|
715 | - Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler. |
---|
716 | |
---|
717 | 10th June 2002 John Allison (opengl-V04-00-03) |
---|
718 | - Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc. |
---|
719 | |
---|
720 | 6th June 2002 John Allison (opengl-V04-00-02) |
---|
721 | - Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc. |
---|
722 | |
---|
723 | 23rd February 2002 John Allison (opengl-V04-00-01) |
---|
724 | - Changes to encourage compilation on Windows in preparation for |
---|
725 | implementation of G4OpenGLWin32Viewer. Removed spurious includes of |
---|
726 | glx.h, unistd.h and assert.h. |
---|
727 | |
---|
728 | 24th August 2001 John Allison (vis-V03-02-13) |
---|
729 | - Limited the printing of warnings in |
---|
730 | G4OpenGLSceneHandler::AddPrimitive (const G4Text& text). |
---|
731 | |
---|
732 | 14th August 2001 John Allison (vis-V03-02-11) |
---|
733 | - Improved KernelVisitDecision. |
---|
734 | - Fixed a few small bugs in multiple "stored" viewers, but see next item. |
---|
735 | - There's an outstanding bug in OpenGL Stored. If there is more than |
---|
736 | one viewer controlled by a scene handler, after a ClearStore on the |
---|
737 | scene handler, e.g., with /vis/scene/notifyHandlers, the first |
---|
738 | viewer to get refreshed should trigger the display list rebuild, but |
---|
739 | the second need not. However, when the second viewer's turn comes, |
---|
740 | the display lists are there, and are called, e.g., |
---|
741 | G4OpenGLStoredXViewer::DrawView calls |
---|
742 | G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but |
---|
743 | nothing appears on the screen. To overcome this there is some |
---|
744 | temporary code in G4VViewer::NeedKernelVisit which marks *all* |
---|
745 | viewers to force a rebuild. To see the symptoms, comment out that |
---|
746 | temporary code and issue these commands: |
---|
747 | /vis/verbose c |
---|
748 | /control/verbose 2 |
---|
749 | /vis/scene/create |
---|
750 | /vis/scene/add/volume |
---|
751 | /vis/sceneHandler/create OGLSX |
---|
752 | /vis/viewer/create ! ! 1 |
---|
753 | /run/beamOn |
---|
754 | /vis/viewer/create ! ! 1 |
---|
755 | /vis/viewer/select viewer-0 |
---|
756 | /vis/viewer/viewpointThetaPhi 20 20 |
---|
757 | /vis/viewer/select viewer-1 |
---|
758 | /vis/viewer/viewpointThetaPhi 40 40 |
---|
759 | /vis/viewer/set/style surface |
---|
760 | /vis/viewer/refresh |
---|
761 | /vis/viewer/select viewer-0 |
---|
762 | /vis/viewer/refresh |
---|
763 | /vis/viewer/select viewer-1 |
---|
764 | /vis/viewer/set/style wireframe |
---|
765 | /vis/scene/notifyHandlers |
---|
766 | You may have to do this too: |
---|
767 | /vis/viewer/select viewer-0 |
---|
768 | /vis/scene/notifyHandlers |
---|
769 | One of the viewers is empty. Curious!! |
---|
770 | |
---|
771 | 9th August 2001 John Allison (vis-V03-02-10-00) |
---|
772 | - Implemented G4OpenGLStoredSceneHandler::ClearTransientStore() |
---|
773 | - Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only |
---|
774 | invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is |
---|
775 | picked up by inheritance anyway. |
---|
776 | - Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc. |
---|
777 | - Corrected order of calling base class functions in |
---|
778 | G4OpenGLStoredSceneHandler::Begin/EndModeling. |
---|
779 | |
---|
780 | 24th July 2001 John Allison (vis-V03-02-06) |
---|
781 | - G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation. |
---|
782 | |
---|
783 | 14th July 2001 John Allison (opengl-V03-02-00) |
---|
784 | - Fixed crash in optimised mode: added Initialise() to viewers so |
---|
785 | that windows are opened after viewers are fully constructed. |
---|
786 | |
---|
787 | 2nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09) |
---|
788 | - Tidied G4OpenGLXmViewer callback code. Removed superfluous header files. |
---|
789 | |
---|
790 | 7th March 2001 John Allison |
---|
791 | - Changed char* to const char* in many places and that gave problems in |
---|
792 | calls to Xt and Xm. Hope all's OK. Differences: |
---|
793 | cvs diff -r vis-V03-00-06 vis-V03-00-07 |
---|
794 | |
---|
795 | 25th January 2001 John Allison (opengl-V03-00-00) |
---|
796 | - Implemented running re-calculation of up-vector in the case of "object |
---|
797 | rotation" (lights move with camera) to prevent "flipping" of view when |
---|
798 | camera passes through up-vector. Note that the default is "camera |
---|
799 | rotation" (lights do not move with camera, i.e., remain fixed relative |
---|
800 | to object) so the default is that this "flipping" can happen. To set |
---|
801 | "object rotation" (lights move with camera) use |
---|
802 | /vis/lights/move_with_camera true (soon to be |
---|
803 | /vis/viewer/set/lights move-with-camera) or click "Object" radio button |
---|
804 | on Rotation Panel in OpenGLXm mode. |
---|
805 | - Changed some objects to references for efficiency. E.g.: |
---|
806 | const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit (); |
---|
807 | |
---|
808 | 22nd May 2000 John Allison (opengl-V01-01-00) |
---|
809 | - Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug |
---|
810 | by sharing static visuals in G4OpenGLXViewer (Guy Barrand): |
---|
811 | static XVisualInfo* vi_single_buffer; |
---|
812 | static XVisualInfo* vi_double_buffer; |
---|
813 | - Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class |
---|
814 | G4OpenGLXViewer. |
---|
815 | - Protected double deletion of window in destructors of G4OpenGLXmViewer |
---|
816 | and G4OpenGLXViewer (Guy Barrand). |
---|
817 | - Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc. |
---|
818 | - Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer |
---|
819 | constructors. |
