So, just trying to gather ideas:

I'm trying to optimise the display of a 3D model on the PSP (giving regard to the model's appearence) for a university project. Does anyone have any thoughts? Even just areas that I could look into? Basically, I want what every graphics programmer wants, for it to be as pretty as possible, as fast as possible - I just want that to be relevant to the hardware.

Any thoughts are much appreciated =)

Well, post the code you have. This is kind of a general field of discussion. There are some things you could do though:
-Avoid texturing vertices as much as you can
-Use the GUM for transforming your models with the hardware instead of transforming them yourself
-Use the least amount of vertices you can, and use indices if necessary
-Using a polygon-clipping algorithm to clip out certain polygons would be really, really nice to have (you'll need to construct a frustum to do that)
-Don't use lighting as much as you can
-Using some sort of terrain rendering system such as octrees or bsp trees

Those are just a few things to look at. Some of them are obvious, but difficult to implement.
