Thanks to #revision2021, I'm learning how to do 2d SDFs... in 1-bit color. It's only been about an hour or so, but the results are very very promising so far!
Once again, Inigo Quilez is a fantastic resource. All I'm doing is plugging in numbers. Though, instead of shader code, I'm using straight up C code with my 1-bit drawing library . It's been interesting converting all the implicit vector operations to vanilla C functions. It's one of the few situations where I miss operator overloading.
Onions have layers. Ogres have layers.
Composing SDFs together is very satisfying. Looking forward to controlling these things with sound/signal.
