luajit interpreter for livecoding graphics by using shaders, images and minimal 2d graphics. For example, it can do things like this and this. It owns a lot to raylib, that is used for windowing, 2d primitives, image loading and shaders. Code is hotreloaded on save by using inotify and webcam is managed with linux
v4l2 drivers, so for now this tool is linux-only.
args: access cli args listed after the script path
audio: connects to JACK to get audio envelope
cam: webcam input
clock: gets and warps time
frag: manage shaders
key: keyboard input
layer: manage different fbo object used as graphical "layers"
lfo: cyclical waveforms
noise: 1-2-3-4 dimensions simplex noise
pad: gamepad input
png: load images (not just png)
rand: various random functions
rl: 2d primitives and other various functions
window: manage window size, position, background and title
the code is functional but still a work in progress; for now this is something made by myself for myself.
this is a memo for myself ( on debian 10 ):
