WLED Soundreactive fork has some early 2D pattern support, with more planned:
The work so far has been done by @apleschu who is now busy with other things, and I’m starting to contribute though so far all I’ve written is some documentation.
My background is driving HUB75 matrix panels (I’m the author of SmartMatrix Library for Teensy and ESP32), but I’m also interested in adding support for more advanced geometric mappings.
Here’s a demo of WLED Soundreactive driving a matrix (using an APA102 to HUB75 adapter board I designed):
Please post in this thread if you have a 2D project in mind and I can try to help out with 2D support. Maybe if there’s enough interest we can add a 2D channel to Discord
