I think trying to be ultra-fast from day 1 might be premature optimisation? Making something that works correctly (with automated tests) can then be made quick.

Though getting things "right" using separate ndarrays for each thing named above, and maybe sellotaping them together into objects later would probably also be processable quite quickly. Yes, I think I'm suggesting prototyping with PDL. It already has code to do OpenGL, including animation, and responding to user inputs (e.g. rotating the view around, while the molecule demo runs). It doesn't yet have textures, but that shouldn't be too agonising to add.
