Hello all,
I am planning to write some code to allow blitting of gstreamer buffers into
osg textures. Eg for playing a video file or a network stream on to OSG
primitives. I did a preliminary search and did not see anyone having gone
down this path before.

Hello everyone,
Simple general question. I searched the archives but didn't stumble on
anything.
I'm currently trying to track down a render-time application crash. What
I'm wondering is how to trace from a crash in the rendergraph to the
associated node(s) in the scene graph. Is there a

That's my best suggestions so far... Far from trivial to set up, very much

You might take a look at the osgEarth project. The

Hello,
I'm currently using an RTT Camera within OSG and I would like to use the

I'm coming up short finding out how to do this. Has anyone done this
previously and might have a code

The best I can do is recommend you do some background reading on
projective textures. I can point you in the right direction, but it's
not my role to teach you the basics of 3rd graphics.
