One way to think about is that these techniques work by integrating exactly the polynomial that interpolates the function where you're sampling it, so you need to resolve the features of the function to get good accuracy.

A great book on this subject is Approximation Theory and Approximation Practice:

It's because when you orthorectify an aerial image, you cast rays from the earth's surface to the camera, so if your model of the earth's surface is off (like when there's a giant man made structure) your mapping also gets wonky.

Check out https://www.chebfun.org/ if you want to see some crazy stuff you can do with polynomials!

Also the book Approximation Theory and Approximation Practice

https://epubs.siam.org/doi/book/10.1137/1.9781611975949

is really great, by the author of Chebfun.

Bicycle Quarterly (magazine by the same folks) is a great read, always such a joy when it arrives in the mail!

This is a nice tutorial on differentiable and inverse rendering (one of the Mitsuba authors also gives the tutorial):

Inverse rendering is such a cool idea... solving for the inputs (3D models and materials) to a renderer such that they match real world inputs (photographs) by computing gradients automatically.

Brompton's (folding bikes) are a really great option, just take it with you.

I've also found Hugo's docs hard to use, but had a great experience learning it from
