Hi Robert
Thanks for your answer...
But I haven't got a clue, what you exactly mean. the geometry and the settings
for this geometry are create by the function osg::createGeodeForImage()
I have read the osghud code. But the only difference is that
osg::createGeodeForImage() doesn't create normals. And the Vec3Array is a
little bit different. In osghud are two more State-Settings:
osg::StateSet* stateset = geom->getOrCreateStateSet();
stateset->setMode(GL_BLEND,osg::StateAttribute::ON);
stateset->setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
Can you give some more information about it?
Thank you for your answer.
Daniel
