I originally pursued a script that would render latitude and longitude gradients on a sphere, and succeed only in finding examples of latitude-equivalent gradients (though they did map to the sphere). Along the way, I started thinking that it would be simpler to map sample maps to a sphere inside the map script, rather than create gradients for use in Lookups.
The question is whether that is even possible. I have seen a map script that has internally generated pseudo-perlin noise uv(w) mapped in the noise generating function. You can find it in Planet Maker 3D by andyz. |

While working on a spherical angular gradient, I realized what I want for "uv mapping" is essentially a lookup. I'm about 1 step away from solving the spherical angular gradient problem, having gotten as far as creating an rgb spherical gradient, which I can turn into an angular gradient once I find out how to sample hsb channels in the script (basically converting rgb to hsb internally). Finding documentation online is nearly impossible for Lua graphics scripting, so it would be very helpful to get help with those two things.
