Detailed Description

Minimal demo of one technique: sampling a circular LED ring out of a 2D Animartrix grid.

Animartrix (16x16 grid) -> ScreenMap (circle of 244 points)

-> Fx2dTo1d (bilinear sample) -> 1D ring

That is the entire sketch. Pick an animation from the dropdown, scrub the speed slider, and see how each Animartrix pattern reads once it has been wrapped around a ring.

Files

File	Purpose
`AnimartrixRing.ino`	The demo: grid, ring ScreenMap, `Fx2dTo1d`, UI
`ring_screenmap.{h,cpp}`	Builds the circular `ScreenMap` inside a rectangular grid
`auto_brightness.{h,cpp}`	Content-aware brightness compression

Run it

pip install fastled
cd examples/AnimartrixRing

Looking for the audio-reactive version?

It moved to examples/MoodRing/. This sketch deliberately has no audio: it is the technique demo, and audio belongs to the product sketch. See issue #2256.
