Triangle Tesselation

[Vincent]

Are there any triangle tesselation function in the PSPGU library like in OpenGL? I want to be able to tesselate triangles for my viewing frustum, but all the OpenGL examples I found use OpenGL functions that I don't think the PSP supports. I'd like to develop my own software tesselation. Right now, I have a process setup:
1) Setup 6 infinite planes that exist on the border of my perspective view plus a little bit for precision.
2) Transform the planes with the camera
3) Check to see if the planes intersect any of the triangles (somewhat like a mesh-mesh collision)
4) Find the points of intersection
5) Temporarily allocate and add a vertex at the point of intersect and index that vertex into my structure

How would I do step 5? I can't think of any ways of manipulating index arrays. I'd like to be able to write an algorithm that will cut down on the amount of vertices in a model, and generate indices for them, then save it into a file for load-time.

Sounds like the clipping used in Quake.

Grab the source for the PSP Quake port, I'm sure i've seen in it in there.

I looked through the source and couldn't find it. Would the Suthland-Hodgman algorithm be a good method to use?
