Release of 0.18

[abdullah]

The thumbnail function uses View3DInventorViewer::imageFromFramebuffer which actually works well for me under Windows and Linux.
The Save picture function uses View3DInventorViewer::savePicture which internally can be controlled with a user parameter to either use:

1. imageFromFramebuffer
2. Coin's implementation of the off-screen renderer (SoFCOffscreenRenderer)
3. FreeCAD's implementation of the off-screen renderer (SoQtOffscreenRenderer) which e.g. supports anti-aliasing. For Qt4 it can also be set to either use FBO or pixel buffers.

I have tried the three implementations.

1) imageFromFramebuffer produces a black image of the required size, no matter which format is used.
2) 'CoinOffscreenRenderer'. I get an exception at:
https://github.com/FreeCAD/FreeCAD/blob ... .cpp#L1115
3) 'PixelBuffer'

In report window:
QOpenGLFramebufferObject: Framebuffer incomplete attachment.

I have no clue what else to try.

('/home/abdullah/github/freecad-build/Ext/PySide/__init__.pyc', '/usr/lib/python2.7/dist-packages/PySide2/__init__.pyc')

Looks good. So there must be another problem. The error-message seems to hide the real issue.

Thanks for checking. If you happen to come across with anything else to try let me know

I have no clue what else to try.

The old Coin3d off-screen rendering is independent of the used Qt version. So, if your Qt5 application fails then your Qt4 application fails too.
For this case there are two environment you can set:

Code: Select all

export COIN_GLXGLUE_NO_PBUFFERS=1
export COIN_GLXGLUE_NO_GLX13_PBUFFERS=1

You linked to my profile rather than my reply, I assume you were thinking about this post? https://forum.freecadweb.org/viewtopic. ... 70#p272496

Are these the only remaining issues?

No, there's been a few more bugs I never managed to report.

Here's one I assigned you since you worked on the tip symbol: issue #3724
If you don't have time to work on it, it's not a showstopper, but it would be nice to get it fixed for v0.18.

The bug getting the most on my nerves is issue #3642. Already with medium complex sketches it takes a considerable amount of time to modify a sketch if deleting of elements or constraints is involved.

Sorry for the late reply.

Thanks for those commands, it did not "fix" the issue but helped debug the thing.

1) Without those lines, the coin3d off-screen rendering will segfault in my computer, regardless of the QT used.
2) With those lines, qt4 works perfectly, qt5 saves a black image of the right size.

Almost a one liner.

This is not straight-forward (to me). Werner will say if it is ok or not...

I have switched to python3/QT5 to be able to use the draft WB:

OS: Ubuntu 18.04.1 LTS
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.15406 +1 (Git)
Build type: DEBUG
Branch: _3642_
Hash: 296471637aaab66f12b1fab4727834a30e3f6d06
Python version: 3.6.7
Qt version: 5.9.5
Coin version: 4.0.0a
OCC version: 7.3.0

Cmake desperately wanted to use python 2.7. If anybody is interested, I tamed cmake like this:

Code: Select all

cmake ../freecadsource/ -DBUILD_QT5=ON -DPYTHON_CONFIG_SUFFIX=".cpython-36m-x86_64-linux-gnu" -DPYTHON_BASENAME=".cpython-36m-x86_64-linux-gnu" -DOCC_INCLUDE_DIR="/usr/include/occt" -DCMAKE_BUILD_TYPE="DEBUG" -DFREECAD_USE_OCCT_VARIANT="Official" -DPYTHON_EXECUTABLE="/usr/bin/python3.6"

You have to start from an empty folder. Otherwise you will end up with python 3.6 as executable with python 2.7 libraries, which will fail.

I tried again the function to save a picture. It complained:

Code: Select all

QOpenGLFramebufferObject: Framebuffer incomplete attachment.
