Render 3D surfaces from mathematical expressions

Enter a mathematical function and have it rendered in a 3D space.

-----

Equations are entered as a function of x and y. An example for a unit sphere would be:

f(x,y) = (1 - x^2 - y^2) ^ (1/2)

"It's amazing, but everytime when the surface changes or when I move it, the old pictures keep "painted" in the window. Is there a way of reparing that?"

SAME PROBLEM HERE!

waaaayyyy to confusing for me lol you need to make one for idiots like to were you just click and drag it or something lol tell me if yo do ever make one for idiots

It's amazing, but everytime when the surface changes or when I move it, the old pictures keep "painted" in the window. Is there a way of reparing that?

wow, such a small widget but powerful rendering 3-d images. thank you

発言者 xinhxinh, # 2007/04/13 22:10:02

Very useful, thank you!

Excellent widget!
Great work

a fractal. kinda hard to tell its one on such a small viewing window.
(tan(x)^2)/(sec(x)^-2)

Wow that is great.

I'm not sure whether i'm in the right place to post a nice function

f(x,y) = 2e^-6(x^2+y^2)-1

this is a Gaussian curve (3d of course)

Excellent!!
While saving image, is it possible to save in a different format??
Anyway liked a lot....
Thanks Man.

A very nice widget!
try cos(x*5)^9 * cos(y*5)^9

発言者 vt-dbnz, # 2006/10/17 22:14:50

Impressive!!!

発言者 Lalacroft, # 2006/09/20 10:18:21

I get a black square when I try to save the image.

Seriously, this is amazing. You are a JavaScript god.

発言者 flanker, # 2006/08/23 7:26:20

How did you do this? Wonderful!

発言者 aleksanteri, # 2006/08/20 14:54:51

CatmandOo: I see. Functions written implicitly like that are extremely difficult to render and would require a FAR more complex mathematical process than the one I have in place (believe me, to implement implicit functions in 2D is a difficult task in itself, let alone in 3D). Each of those quadrics (and a large majority of other implicit functions) however can be manipulated to make Z the subject and with the possible future +/- operator they can be rendered in full.
If you need to render more complex surfaces you could buy a program such as Mathematica.
