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)

A precise view of the section of road and cliffside visible from my window.

does anyone know how i can save widgets to a file and take them to another computer (the internet on that one doesnt work) ? i did this with skins by downloading them in firefox and saving them to a CD but when you try this with widgets it says you need to download opera.

At the moment, to look for f(x,y)==0 AND g(x,y)==0, I type "abs(f(x,y))+abs(g(x,y))". Sometimes with an additional sqrt(..), depending on how the neighbourhood of the root is shaped.
To make this more useful, it would be a great help to have colored isolines in the dynamic (wireframe) view, or at least different colors for positive and negative values. It's quite hard to guess from the black lines where the root might be.
