Rats.  That's annoying.  Ah me.

I'm not sure what immediate mode is.  I'll look it up in the QD3D manual 
in a minute.  Basically, I'm using Joe's Queeg framework, as I generally 
learn systems by hacking existing code.  So I'm just duplicating Joe's 
approach.  Maybe Queeg was meant to be small and exemplory and isn't 
really fleshed out in the sense you're describing above.  At any rate, 
during the submition loop, Queeg makes calls like this:

Q3TriMesh_Submit( &mTriMeshData, view );

Where mTriMeshData is of type TQ3TriMeshData and view is of type 
TQ3ViewObject.  So, that's how I do it too because I didn't know there was 
any other way.  Any rate, I can't figure out how to group these things. 
Are you saying they're not even the right type for grouping?  That I need 
to convert them into TQ3Objects somehow?

Would the conversion make the program run faster btw?
