Fibonacci lattice as additional sampling method #979
Comments
Hi Matteo, thanks for considering a contribution. You mean a new method for
the HomogeneousSampling?

… Hi,
I was looking at the available sampling algorithms in the package and I
was wondering if it would be of interest adding an area preserving method
for evenly distributing points on a sphere. I'm currently using the
Fibonacci lattice for this task.
Let me know if you think this could be an interesting addition, so I can
propose an implementation :)

Hi @juliohm! Yes exactly, you're for sure more familiar than me with this method but here a quick reference: https://observablehq.com/@meetamit/fibonacci-lattices That would be nice in order to have a "tesselation method" for the sphere, avoiding more complicated implementations like the icosahedral Goldberg polyhedra. I work in SatCom and for example I use the Fibonacci lattice on a sphere to obtain a "grid" of points regularly distributed (preserving density per area) on Earth to collect statistics (of course here there is an approximation when you translate to lat-lon on the ellipsoid). |
That is great @mcontim. Appreciate if you can submit a PR for review. We need to figure out if this is a new case of the I understand that this algorithm you are interested in is deterministic, even though we can create some randomness as explained here: https://www.johndcook.com/blog/2023/08/12/fibonacci-lattice/ Let's brainstorm the best place in the PR. |
Thank you @juliohm for the quick reaction! |
@mcontim I think this method deserves a new Did you have a chance to take a look into it? |
@juliohm I'm planning to work on the PR in the next couple of days (it was a busy week of coding this one :D ). I agree on the new |

Hey, @juliohm . I've implemented this for Disk and Sphere. Does the PR usually comes together with an updated docs, or are docs PR done separately? |
Please feel free to add docs in the same PR. It is nice to see examples.
