That's some fascinating work.

I'd certainly recommend `user_defined` camera for this purpose, as you 
"only" need to plug in formulas, don't have to wrap your brain around 
making a corresponding mesh, and don't get excessive memory requirements 
at high resolutions.

As long as the functions don't do anything particularly fancy, I don't 
expect render speed to be a problem. At the very least it should beat 
the mesh camera hands down anytime.
