Please Help,

I am still pretty new to OpenGL and have a question regarding the rendering of contour lines.

I have a text file with X, Y, and Z coordinates that I have been successful at rendering in OpenGL - however, now I would like to place over that drawn image a series of contour-lines. I have another text file that is made up of node numbers (where each node is a single X, Y, and Z coordinate and represents a Point in the original image) and what I would like to do is lay those nodes as contour lines over the previous image.

Since all this is still fairly new to me, can anyone point me in the right direction to solve this in the most efficient manner?

Thanks for any help.
