  • 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)
  • u/DataMeta
    WOW!!! #smoke #realistic #compressed

    Abstract smoke! Nice! Could look nice if it left a trail?
  • u/joeytwiddle
    Tried shadowBlur but very heavy. Trails look better anyway: x.fillStyle='#fff3',t?x.fillRect(0,0,999,800):c.width=999;x.beginPath();w=540,t?m=[w+S(t)*340,w]:p=[];p.push([[...m],5]),p.map((z,i)=>{k=z[0],k[0]+=S(i+t),k[1]-=z[1]+S(i*8),x.lineTo(...k),x.stroke()})
  • u/trancor
    Oooo, I like that, great idea! I'll have to try incorporating that into a remix. Thanks joeytwiddle!
