    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.

Ray Marching SDF Smoke #improved resolution

u/tomxor

Exchanged marching depth for resolution... makes it a bit less 3D but a but more smokey i think.

I see that smoke is a trend now so i made smoke particles c.width*=1;t||(s=[]);s.push({v:0,V:Math.random(),x:960,y:900});for(i of s){x.fillStyle="#0003",x.fillRect(i.x,i.y,9,9);i.x+=i.v,i.v+=S(t*t/9+i.V)/99,i.y-=i.V*S(i.x*i.y)+2}

Ray Marching SDF Smoke #improved fps

u/tomxor

huh, did not know about Math.hypot, also it's weird how sensitive V8 is to globals... or rather how it seems incapable of optimising them into locals itself.

Ray Marching SDF Smoke

u/tomxor

Runs significantly faster in FireFox for some reason.
u/tomxor

Part of the smokeyness is obtained by exploiting artifacts in the ray marching algorithm itself, by only marching a constant and very short depth (4 steps) smooth aberations appear around the true volume (representative of the sphere tracing)
