[osg-users] Animating Textures

[sam]

I can appreciate your stance on going to shaders, and I completely agree.
I'd like to quickly prototype this up and swapping to shaders will,
unfortunately, take me a little bit. Is there an example of modifying the
texture matrix? Also would I be better of attaching an update callback to
the state set itself?

Thanks, Sam
