Yes, this is common way to implement things like distortion correction -
see src/osgViewer/View.cpp's implementation of spherical distortion
correction.  All you need to make sure is that RenderOrder is set to make
sure the RTT slave Camera is drawn before the other Camera's that use the
result.

Thanks.  One more question...

What I am trying to do is render an entity in my scene from 3 (Front, Top, 
Side) views, at a constant range/distance.  Is a slave camera the best 
approach.  I have some confusion regarding using slave cameras vs. multiple 
views.
