Hi,
There are simple questions:
I was going to point to do some examples, but then I saw there really
aren't good examples for these :-)
What do I need to do to make sure transparent object show up properly?
ss = node->getOrCreateStateSet();
ss->setMode(GL_BLEND, osg::StateAttribute::ON);
ss->setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
ss->setRenderBinDetails(1, "DepthSortedBin");
How do I cull the back face of polygon?
cull = new osg::CullFace();
cull->setMode(osg::CullFace::BACK);
ss->setAttributeAndModes(cull, osg::StateAttribute::ON);
Thank you!
You're welcome. In general, most OSG state works this way. You can
either find an osg::StateAttribute descendant that handles it (as in
CullFace), or if it's normally just a glEnable()/glDisable() setting,
you can just set the mode directly (as in GL_BLEND above).
