My first question is whether it is possible to render an RGB texture with no alpha channel with binary transparency. I'd like to map a specific color to 100% transparency. Would this require shaders? If so, could someone point me to a good resource for coding shaders in OSG?
My other issue is a rather strange behavior I have observed in OSG. My app is constantly dumping a lot of points into the scene graph (osg::DrawArrays with PrimitiveSet::POINTS) while updating a transform. I have run into an issue in which nothing gets rendered at all, unless I remove either the point insertion or the transform update. Does anyone know what could cause this behavior?
