Hi again,
after Daniel suggested me to use QGLPixelBuffer to render offscreen I did,
and nearly everything works perfektly now. Except the backround color is not
set to the color I specified with setClearColor() and every
SceneView::draw() generates an error message:
"RenderStage::drawInner(,) OpenGL errorNo= 0x502"
This error is:
#define GL_INVALID_OPERATION 0x0502
I'm pretty sure the same code rendering onto a normal GL graphics context
doesn't throw this error.
What am I doing wrong? Can you help me with that?
I am afraid I'd need to be clarevoyant to be able to divine what might be wrong.
You'll need to step through things at your and in a really mathodical
way. First up I'd recommend try using the CVS version of the OSG, it
contains various bug fixes, its a long shot but there is a chance it
may help.
Next up enable more fine grained error checking via:
sceneview->getState()->setCheckForGLErrors(osg::State::ONCE_PER_ATTRIBUTE);
Next up do you have more than one graphics context in your app??
Robert.
