Hi Jason,
I'm not sure what the problem would be, try running "osganimate -overlay" and see if it works for you. If it does, then there shouldn't be a problem with the code in osgspheresegment. One thing I notice is that the code in osgspheresegment sets the tex env mode to DECAL, but I don't think this needs done as the OverlayNode does that for you already. Try removing that line and seeing if it works for you.

I got it compiled, and removed the #if so it would force it to run using the createOverlay code. Forgive me if I am missing something, but I don't see any grid lines being rendered on the terrain. Does this particular example have a bug? I've tested this a few times and can verify that the overlay code is running but I just don't see the grid lines.

There used to be an example of exactly what you are trying to do in the osgspheresegment example, but it is no longer in there. You can see it here though: http://www.openscenegraph.org/viewcvs/examples/osgspheresegment/osgspheresegment.cpp?rev=1.18&view=markup Just do a search for createOverlay and you'll find it. Good luck!

I'm interested in laying down grid lines where the spacing can be changed by the user. Maybe I'm overthinking this, but I'm looking for a way to basically lay the gridlines down directly on the 3 dimensional terrain. Is there something in OSG that allows someone to lay a texture upon another texture or am I better off using shaders, or something else to achieve this effect? I've checked out various examples...would OverlayNode or TexGenNode be of any use to me?
