    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.

#raytracing z = sin(sqrt(x*x + y*y) - t)

u/pavel

Also a pretty generic ray tracing 'engine.' Change f to trace other things.
u/pavel

Style remix, no idea how the code I'm remixing works yet. It does not look to do ray tracing so its clearly better.
u/primo

The original uses z + ∂/∂y z for saturation, which looks about right tilted at or near ~26.5°.
u/pavel

for(c.width&=i=10368;i--;x.fillRect(i&127,i>>7,f(.7),1))f=n=>(z=5-i/3e3-3*n)>S(Math.hypot(i/64%2-1,i/5e3-n)*9-6*t)?f(n+.03):--z*.4 is a better one, no weird view prism.

Parallax Mountains ⛰️

u/KilledByAPixel

These are non-repeating mountain ranges, using a similar formula used in my #JS13k game Space Huggers
u/rep_movsd

#parallax #landscape
u/rodrigo.siqueira

The first game where I saw this effect was in Moon Patrol, I liked it a lot, it was great and also had a great music. I think it would not be difficult to recreate Moon Patrol from this Dweet.
u/andrea270872

moon patrol ate so many of my coins!! :D
u/tomxor

Pretty sure I first saw the effect in StarRay (Atari ST), I think I enjoyed the music more than the gameplay, no coins though :P

Genius.
u/Joachim

Wow. This is very clever
u/rodrigo.siqueira

Now I can't look at city buildings without thinking about this. See https://en.wikipedia.org/wiki/Tetris_effect The Tetris effect (also known as Tetris syndrome) occurs when people devote so much time and attention to an activity that it begins to pattern their thoughts, mental images, and dreams. E.g. People who have played Tetris for a prolonged amount of time can find themselves thinking about ways different shapes in the real world can fit together, such as buildings on a street.
