Hi Cory, Well, as I said, I'm not the one which can best answer you. However, I think using generated geometries in OSG is rather simple. It depends of course on how they are stored.
I suppose that a low-level code that adds each triangle into a geode would certainly not be very efficient, but at least would be the simplest and the less error-prone code that works with almost everything. Maybe you could try. If you write a kind of importer for files generated by a "geometry engine", think about proposing your work as a plugin (such as "osgDB_OpenCascadeFormat" if such a format exists). But maybe your "geometry engine" can export models to a common format, supported by OSG? This would be a very simple solution, IMHO.
