- Understanding 3D circle parameterization

Hey

I saw this post: https://www.physicsforums.com/threads/general-equation-of-a-circle-in-3d.123168/ trying to understand 3D circle parameterization.

I saw the formula given by Hootenanny

But I didn't understand it and would like some help.

What are u and n and how can I find/calculate them?

thanks!
