So I'm trying to independently study physics. And long story short I found this function:
f(x) = sin(x^2+y^2)/(x^2+y^2)^0.5

Adjusting for scale (and swapping y with z), I created a script to graph it in the Roblox 3D world and took a picture and made decal so you can see ti here:

I just think it looks really cool.

Inspired by this, I created a 3D Function grapher here:

Maybe I could turn it into a plugin (it would be faster as a plugin).

I tried doing a different graph using z= in place of the y= and x^2+y^2 as the equation... it doesnt seem to like it

I think it will render faster if you were to change the position of them each time instead of reinstancing them

* f(x,y) = sin(x^2+y^2)/(x^2+y^2)^0.5

@LegendaryAccount

The reason it is slow, is because I have to have the server calculate the positions. The reason for that is because the server is the only thing that can use loadstring. So it could run much faster if not for this. I'm thinking about making this a plugin and that would make it run much faster. So much, in fact, that I need to make sure to add a delay :P

The speed you see now is because of coroutines. :)
