    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.
