    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

A three-way adversarial deep neural network learning to draw a cat.

this is clever af
u/BirdsTweetCodersDweet

How is it a neural network? You're just drawing random squares on a cat emoji :P
u/pythech

whoosh
u/magna

Yeah, sorry, it was a bad joke. Just transferring random rectangles from an off-screen canvas. The only catch is the use of valueOf to cut down on the function call ()s.

great attempt! not sure it is possible to get smaller without cutting something. in this case the X%4 part is necessary to make the trees varying heights
u/FireFly

"boring" -1, distribute the ?: across args in the fillRect: x.fillRect(t?X-r*i/8:i*8,t?600+(r*8&3?i-h:h-i):r*600,t?i/4:h,t?2:r). Or more depending on what artistic tradeoffs you're okay with, e.g. just always setting height to r isn't terrible
