| Summary | 0024868: Visulization, TKOpenGl - Exception when many views are created | ||||
| Description | When more than approximately 70 views are created in Draw via vinit, an exception is thrown in the call to wglCreateContext (aWindowDC); in OpenGl_Window::OpenGl_Window (const Handle(OpenGl_Display)& theDisplay, const CALL_DEF_WINDOW& theCWindow, Aspect_RenderingContext theGContext, const Handle(OpenGl_Caps)& theCaps, const Handle(OpenGl_Context)& theShareCtx) Is this a limitation or a bug? The behaviour is the same in OCC 6.7.1 beta. Similar behaviour can also be reproduced with the ImportExportSample (either MFC or CSharp) using menu "Window > New windw" to create new views. | ||||
| Steps To Reproduce |
pload VISUALIZATION
for {set i 1} {$i < 1000} { incr i} {puts $i; vinit}

There is limitation of number of views that can be created, currently 100, see http://dev.opencascade.org/doc/refman/html/class_visual3d___view_manager.html In my experiment using OCCT 6.7.0 vc8 32-bit and OCCT 6.7.1 beta vc10 64-bit it stops exactly on 101-th view: Draw[1]> pload ALL Draw[2]> for {set i 1} {$i < 1000} { incr i} {puts $i; vinit} 1 ... 100 101 An exception was caught 000007FEEB8FFD38 : Aspect_IdentDefinitionError: GenId Next Error: Available == 0 ** Exception ** 000007FEEB8FFD38 : Aspect_IdentDefinitionError: GenId Next Error: Available == 0 Draw[3]> exit If you confirm that it stops on 101-th view (not 71-th as you reported), I suggest we close this issue as known limitation. If it fails earlier, please try to debug in your environment, as we cannot reproduce it here. |

It seems it is dependent on the graphics driver. Until now I had: ATI FirePro V5800 (driver: 9.3.3.3000), Win 7 Pro and received the following Draw output: ... 86 An exception was caught 0082F028 : OSD_Exception_ACCESS_VIOLATION: ACCESS VIOLAT ION at address 0x00000008 during 'READ' operation ** Exception ** 0082F028 : OSD_Exception_ACCESS_VIOLATION: ACCESS VIOLATION at a ddress 0x00000008 during 'READ' operation After updating the driver to: ATI FirePro V5800 (driver: 13.350.1012.0), Win 7 Pro I received the same output as you. I tested it still on some other systems. The result was correct (100 views) on: - NVIDIA Quadro FX 4600 (driver: 9.18.13.3165), Win 8.1 Pro - NVIDIA Quadro FX 1600M (driver: 8.17.12.9573), Win 7 Ultimate There was a problem in the following case: - Intel HD Graphics 4000 (driver: 9.17.10.2875), Win 8 Pro Output: 33 An exception was caught 01BEBCB8 : Aspect_GraphicDeviceDefinitionError: OpenGl_W indow::CreateWindow: wglShareLists failed. Error code: -1073278755 ** Exception ** 01BEBCB8 : Aspect_GraphicDeviceDefinitionError: OpenGl_Window::C reateWindow: wglShareLists failed. Error code: -1073278755 |

The exception looks like limitation of OpenGL driver - there is nothing wrong in OCCT (although it should be checked that code has appropriate checks in case of failure). However the problem itself can be resolved by re-usage of the single OpenGL context instance across all views (already planned but nowhere announced since this change will make no differenced in most cases, rather than this one accidentally appeared). |
