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)

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)

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

If you need to render more complex surfaces you could buy a program such as Mathematica.

Thanks for your reply. I haven't ment animated functions.
I've ment quadrics:

It would be possible to implement an extra variable that represents time to create animated surfaces. It would not require a great deal of more code to do so, but will be very slow to render and there would be no way of saving it as an animated gif or anything like that so it does not have a very high priority at the moment. Maybe in a few months I will consider it again.
Your previous suggestion of multiple surfaces on one render would be a good feature but would require alot of change to the interface which I cannot be bothered to work on too much at the moment. The closest thing to this that I am likely to do in the near future is add the option of a "plus or minus" sign at the start of a function to let you draw complete spheres and toruses etc. instead of just the upper half.

Simply "getting started" and "variables, functions" as link text would be much easier to spot, without reading all text.
