[osg-users] Draw Instanced

[sam]

Hi All,

I'm having some trouble getting my code to use hardware instancing. I've
referenced OSGEarth, DrawInstanced example, and a few different code
samples on the web. I've gotten pretty close but I seem to be at a bit of
an impasse.

This screenshot shows what the map looks like with the default rendering:

This screenshot shows what the map looks like after I apply my instance
rendering code to it:

The map is composed of a lot of little nodes. I figured instanced rendering
would be helpful in this case. The map has ~4000 individual nodes. Two of
the nodes are repeated 465 and 266 times. I have trimmed down my code and
it is posted here:

>From what it looks like. Its rendering one copy of every nodes but not
anymore that that. I have commented out lines 215 to 224 as it doesn't work
at all. Any insight or help would be greatly appreciated.

Thanks, Sam
