Ideas on pixel mapping layout for circle/sphere

Hey all. I’m working on a project that will have LEDs laid out on a shape that most closely resembles a half-dome. So circular in nature but laid on a partial sphere (imagine the front of an eyeball covered with pixels). One could go back and forth across like a grid (with uneven rows), or lay it out like a spiral from the center, or use concentric circles.

What would you recommend as a good starting point for mapping this kind of geometry?

Thanks!

what kind of LED mounting format (like strip, pebble, or cob), and what direction are you going to view it from?

I have the GS8208 strips that can be soldered together. It will be viewed from the front/side, like you’re looking at an eyeball essentially.

I think you’d have a hard time laying down strips on a curved surface, especially in any non straight pattern. The strips themselves are flat and can only curve forward or backwards. I might try making something close to a sphere out of thin cylindrical sections. You can lay strips along the sides of those. Making a spiral or concentric rings is going to look bad unless you are able to fold the strips.
