    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.

Circle of Light

u/tomxor

:D I tried a similar thing at one point. Making the source this wide has some interesting affects on the shadows in this scene.
u/ciaccodavide

yeah! It's fun playing with the light source! And raymarching is awesome, I still need to look at your code to understand it better "^_^
u/tomxor

Give me a shout on discord if you've any questions. One part I'm still trying to understand is the probability distrubution of the reflections which I accidentally got non-uniform (which is good for diffuse, ideally want it lambertian) due to how no correction is made upon intersection.

Sometimes Im amazed at how stupid I am: 'filter:invert(';for(let z,A,B,n,X,Y,i=24;i;X+=A,Y+=B)(40+X/48^16+Y/48)%15>1?x.fillRect(X,Y,n/++z**.5,1/8):(z=1,r=(n+7)**i*t,A=2*S(r),B=2*C(r),--n)||(n=8,X=1280+i*S(t),Y=720+i*C(t),--i);
