Suitable intro to 3d for games?

I'm just making the move from 2d to 3d gfx in Blitz and I want to get a friend of mine to make the gfx. He has experience with 3D drawing packages, but could anyone give a few hints on what the important methods are for coming up with models that will move at a decent realtime frame rate?

Thanx in advance

I don't think you could do any better than to point him to Psionic's excellent tutorials:
