3D curves

AFAIK, You can use a bunch of 2d bezier curves to construct a 3d bezier patch.
EDIT: actually, there's an article about it here on gamedev.

I'm not trying to create a surface, but rather a path in 3D space. (Take a look at the path object in Blender. I can place control points anywhere I want)

You can use splines (such as Bezier curves) in 3D as well as 2D. Some of the details are a little different (such as computation and handling of coordinate frames), but the basics - evaluating positions and so on - are the same regardless of dimension.

It works exactly the same as 2D curves only with a third equation to represent z.

Yes, thanks! I got it working now!
