[osg-users] Getting a callback to update shaders?

[Rowley, Marlin R]

Hi,

I have a camera in the scene that I made. It has geometry attached to it to represent it.  I also have a shader attached to some geometry in a scene where it uses the camera's view/projection matrix.  I've set up a callback (event driven) that when I move the camera with keyboard keys, it redraws the object correctly, but the shader on the geometry doesn't update from the view/projection matrix change.  What am I missing? I've been at this for 9hrs and can't find any example that implements that I'm trying to do.

Thanks,

-M
