Hi Marcos,
That's what I thought : it comes from the OpenGl driver ("from
/usr/lib/dri/i915_dri.so").
I think it comes from the way I init the viewer : just after the Viewer is
created, I set up default OCC lights:
myV3dViewer->SetDefaultLights();
myV3dViewer->SetLightOn();
I will try to move this out from the C++ Display3d.cpp file to pure python.
It will be easier to bug and, most important, to fix. Don't know yet how I
can test the modification I make : I don't have a Linux machine with this
specific graphic hardware. The best would be that you compile pythonocc
yourself and test if. The latest revision of the svn trunk is much more
convenient to build and it can be done easily.
Regards,
Thomas
