| Summary | 0023668: OCCT automated testing: Using Mesa3d for 3D visualization on virtual Windows machines | ||||
| Description | Some time has been spent on attempts to use Mesa3d (http://www.mesa3d.org/) as OpenGL API implementation used by DRAWEXE on virtual Windows machines. Here is the summary of the results (quite poor in fact): 1. No Mesa, using default OpenGL 1.1 implementation provided by Windows. - Only very basic OpenGL features available, some new functionality that will require OpenGL 1.2+ might now work in the future. - Highlighting of detected subshapes (cyan color) is not visible on snapshots created by vdump command (0023525). 2. Mesa3d 6.4.1 (Win32 binaries attached). - Supports OpenGL 1.5 and some useful OpenGL extensions, including FBO. - Test 3D view seems to work. - But highlighting of detected subshapes (cyan color) does not work either in the 3D window or in snapshots created by vdump command. 3. Up-to-date Mesa3d 9.0. Two kinds of rasterizers have been tried: - Win32 GDI-based - Gallium GDI-based rasterizer built with LLVM 3.1 (http://llvm.org/). Both versions of opengl32.dll crash but differently. Corresponding bugs have been reported to https://bugs.freedesktop.org: - https://bugs.freedesktop.org/show_bug.cgi?id=58716 - https://bugs.freedesktop.org/show_bug.cgi?id=58718 Before the patched Mesa3d is available, a workaround will be used: vis tests will be run on a dedicated physical Windows station with hardware-accelerated OpenGL implementation. | ||||

4. Mesa3d 7.8.2 (Win32 binaries at occt653products). - Supports OpenGL 2.1. - Test 3D view seems to work. - Highlighting works correctly but it is possible to let down viewer by clicking on 3D viewer within already active local selection. Shouldn't limit usage (testing). |

OCCT patch available for review in branch CR23668. Introduced new Draw Harness command dlibpath to prepend dynamic libraries search path. It uses SetDllDirectory on Windows so it is possible to specify path to custom opengl32.dll (changing PATH environment will not work due to DLL search path order which prefer System32 first). Notice that to take effect this command should be called each time before pload VISUALIZATION. For example: dlibpath "g:/occt-3rdparty/occt653products/mesa-7.8.2-vc9-32/bin" pload VISUALIZATION vinit vglinfo |

Branch CR23668 reviewed without remarks, ready for testing. Dear bugmaster, It is necessary to run the complete set of tests under Windows using Mesa 7.8.2 DLLs provided by kgv, paying special attention to the test cases using highlighting. |
|
|
Patch was updated and pushed to branch CR23668_1: - dlibpath was removed as not very useful to users. - DRAWEXE now parses advanced environment variable CSF_UserDllPath to prepend DLL search path. Windows-only! So now CSF_UserDllPath should be defined before starting DRAWEXE in environment scripts like: set "CSF_UserDllPath=g:/occt-3rdparty/occt653products/mesa-7.8.2-vc9-32/bin" DRAWEXE pload VISUALIZATION vinit vglinfo |

Dear BugMaster, Branch CR23668_1 (and products from GIT master) was compiled on Linux and Windows platforms and tested. Number of compiler warnings: occt component : Linux: 3 (3 on master) Windows: 85 (85 on master) products component : Linux: 9 (9 on master) Windows: 54 (54 on master) Regressions: No regressions Improvements: No improvements Testing cases: No testing cases Testing on Linux: Total MEMORY difference: 221077480 / 219733800 Total CPU difference: 8397.74000000028 / 14274.820000000042 Testing on Windows: Total MEMORY difference: 311007052 / 294553020 Total CPU difference: 11591.6875 / 11675.59375 There are not serious differences in images found by testdiff. |
