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 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.

Try these: cos(cos(10x)*cos(10y)) and sin(sin(10x)*sin(10y))
please post any good functions - anyone have any idea how to make a whirlpool?

It would be really great, if you ad some more functions and options, e.g. that you can draw two or more functions together and determine the intersection function.
Further the Natural Logarithm is NOT log(x), it is usually ln(x). The Natural Logarithm is the logarithm with the basis e^1.
It would be nice if you add a Logarithm with the basis 10, usually log(x).

I like your other widgets too, they are outstanding (and not only because most of the other widgets lack originality and quality).
Regards,
Wolfgang
