WLED export

[TheMariday]

As a user I want to be able to export to WLED so that I can use their effect driver.

This might have to be a quantised 2D projection

yeeaaah.... another thing I've started to dig into - not for my 3D camera mapping project, but for a graph-based mapping project of mine (tiktok demo) that is good for 2D stuff.

+follow for if you get to it first. Or if not, I may dig into this within a few months.

I have some ideas:

• use RANSAC
• pick random LEDs & their nearby neighbors (from a KD tree?)
  • or not so random, find nearest neighbor for each LED, and select from 20% percentile of LEDs with closest neighbors?
• pick a minor rotation amount + grid spacing for the neighbors to fit well
• layout the rest
  • for each bin, keep track of how far off the LED is from its ideal center
  • if a bin would be a better match for a later pixel, go back and re-place previous pixel
  • if no free pixel < 1.75 pixels away (tuneable?), give up - bad map
  • rank based on minimal total graph size

That way, mapping something lightly misaligned should still be able to be put on a grid neatly

did you have any approach in mind?
