This formula is pretty interesting:
abs(cos(x) + cos(y) + cos(z)) - 1
It is a combination of two of the formulas included with k3dsurf.
here is a picture

|
|
int(cos(x)) + int(cos(y)) + int(cos(z))
You may want to try this
(sqrt(x*x/2+y*y/3)-3)^2 + z*z/4 -1
Here is an interesting formula in Cylindrical Coordinates
r = cos(sqrt(pi*pi - z*z))
and in Cartesian Coordinates it is
x^2 + y^2 - cos(sqrt(pi^2 - z^2))^2
Here is a formula that looks like a tank or a capsule:
x*x + y*y + z^4/49 - 1
Guess what this looks like:
cos(sqrt(pi - x*x - y*y)) - z*z + 1 |
