Were there any attempts to extract track data (textures, faces) from the N64 ROM ?

I'm wondering if the tracks stored in the N64 cartridge are in a similar format to what is used in Wipeout 1 / 2097 on PS1.
Those two games store tracks inside files with TRV (vertices), TRS (sections), TRF (faces) and VEW (view) extension. Textures are stored inside LIBRARY files.

I wanted to take a look at the N64 rom but don't know where to start.

EDIT: this screenshot show Qoron IV in Unity (from Aybe), so this has definitely been done.

EDIT2: here is relevant post
