I have a guest staying over, and they asked me if I could model an astigmatism.
I was wondering if anyone had ever thought of implementing Zernike Polynomials
for modeling common optical aberrations.
The general concept seems simple enough. I was able to model a simple
astigmatism (n=2, m=2) as an isosurface lens using ior, but I didn't seem to be
able to get the desired results using the user-defined camera feature.
I think I'd need to set the direction vectors as the normal vector of the
surface in order for it to work the way I think it ought to.
However, considering that it seems to a common way to alter a lens to correct
for various effects, maybe it would be a good idea to have a decent sized set of
functions to apply to the camera.
