Interesting, will try it out. Thank you!
Tbh, I tried several different functions, but nothing worked better than inverse quadric function. Though, I'm not sure if I tried anything without decay
One interesting group is the compactly supported RBFs, for example those of Wendland https://math.iit.edu/~fass/603_ch4.pdf the advantage being that the resulting linear systems are sparse, useful when you have lots of points to interpolate and "gaps" is not an issue.

Mesh gradients are a powerful way to create smooth, organic color transitions. Traditional techniques like spline-based interpolation or multiple overlapping radial gradients can be effective—but they also come with trade-offs: visual artifacts, complexity, or the need for structured meshes.
In this article, I’ll show you how to use Radial Basis Function (RBF) interpolation to generate seamless gradients from just a set of colored points. This approach is portable, flexible, and simple to implement.
RBFs are splendid, but you don't need to have them "decay with distance", indeed, ones which don't (mutliquartics etc) often have better approximation properties and better-conditioned linear systems to solve, give them a go! https://www.sciencedirect.com/science/article/abs/pii/S09557...

In London it has barely rained since the start of May, after the sunniest and warmest spring on record. Obviously as an Englishman that sounds pretty great to me but it is not typical at all.

As sure as eggs is eggs, there will be sightings of exotic predators (puma, leopard) by little old ladies in the next weeks ...

Off by 2, not so bad
That's air-conditioning rather than alternating-current (both legal in the UK).

Spending $25k on a car (if they exist) is just an insane thing to do in my opinion. In the UK we are quite lucky in that the used car market is very good. I always just buy a ~£1,000 diesel and run it into the ground, then rinse and repeat.
I think in 17 years of motoring I've spent around £5,500 in total on cars.
A friend and I bought a car with a busted door for £100 some years ago, we got a cheap replacement door, incompetently resprayed it to be roughly the colour of the rest of the car and sold it, for £100 :-|
