2005 called. They want their cheesy school supply designs back.

Porting GLSL shader code from shader toy to ANSI C. Just to see what would happen.

Attached is a frame based on this shader toy example:

My terribly unclever C code took 23 seconds to render this 720p image with multithreading enabled.

scale [phasor 8 0] 0 12
add zz 72
mtof zz
phasor zz 0
bitosc zz 3 6
mul zz 0.3
wavout zz "pewpewpew.wav"
computes 2

chaosnoise 1.9 4000 0.141
valp1 zz 300
mul zz 0.5
wavout zz "static.wav"
computes 60

Composing SDFs together is very satisfying. Looking forward to controlling these things with sound/signal.

Couldn't resist trying to play with color. I managed to work in a hack that for all intents and purposes seems to do anti-aliasing without oversampling.

Onions have layers. Ogres have layers.

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[0]. 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 [1]. 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.

Here is a modification of the patch using generative vocal utterances instead of real human speech.

I call it: "belchy robot".

Had this amazing realization that 1-bit (okay, 2-bit) audio would make for a great carrier signal for a vocoder/talkbox.

spent this afternoon playing around with 1bitr:

I used some #janet and shell scripts (paste ftw) to assist with sequencing. The amalgamated output can be found here:

Baby croissant :3

My naive attempt at constructing a bezier circle ended up producing a very friendly-looking shape.

Bottled my traditional mead today! If I had known this was only pitched in January, I wouldn't have bottled but oh well. Cleared up pretty nicely.

New frame idea. #thecandycrystalrainbowcodex

First draft of my diagram for Seq16, a 16-step sequencer in #monolith, controlled via the monome grid.

Works in btprnt okay!

It took some tweaking, but I managed to get the font2c program I found online yesterday to generate a font tileset in a C-friendly XBM format.
