Hi Fabien,
Without looking at your specific code in detail:
There is no graphics context associated with the camera directly after
creating the viewer. Make sure viewer->realize runs before accessing the
guts of context-specific stuff.
Your crash most likely is due to having a nullptr-access to the
graphics-context. Check first if the "camera->getGraphicsContext()"
returns a valid pointer. If not, you're setup isn't yet complete.
If you still got problems, you might consider presenting some minimal
example that reproduces your problem.
Cheers
Sebastian
I'm trying to mix Qt and OSG contexts according to this implementation :
QQuickOSG (https://github.com/Sparadon/qquickosg/blob/master/qquickosg.cpp)
He had initialized the FBO like this (line 332) and then use the FBO Texture id
to initialize the Qt side Texture (line 374).
My pipeline is a little bit different but I have the same objects and I don't
get why my apply() crashes. Maybe it misses up with Qt stuff...
Cheers,
Fabien
