Moving 3D #Grid (improved)

u/Joachim

Nice!! You might find this helpful: with(x)for(i=z=c.width=400;i--;beginPath(stroke()))moveTo(i*9,99),lineTo(i*z-1e4,z),fillRect(0,99+i,z,(S(z/i+t*9)>.9)&&i/50)
u/lewdev

That's awesome! Thanks! I'm trying to figure out how to depict things in 3D; this and your website helps!
u/Joachim

u/lewdev no problem! Glad I could help out :D
