How to calculate a tube

[strange]

Hi,

I would like to have a tunnel or tube in my scene. How does the mathematics work if I would like to store the vertices in an array and have to calculate them without using the OpenGL library.

Actually I would prefer to set a path and the algorithm is calculating the tube around it.

I just can't figure out how to do this and haven't found any tutorial.

thanx
