If the data isn't structured, then maybe just plot a sphere at every vertex -
adjust the radius until they overlap and form a "surface".

Likely though, your data is already just a mesh definition.
(probably the famous "Utah teapot" : https://en.wikipedia.org/wiki/Utah_teapot )

You could probably just edit your file and save it as an .inc file, and render
the mesh directly,

or read the vertices in 3 at a time and use an array to store them,

or just make triangles in a mesh{} inside of your #read loop.
Look up #read and other file comands in the docs and how to use a while() loop
to read until EOF.
