Elsewhere on this site you can find mcjTracer, a plugin that lets you display lines and wioreframes.

The mcjTracePath script is designed to produce special obj files displayable by the

"mcjTracer plugin. Select one or many objects in the scene, ex: 10 finger tips

"Press the save button and you will be saving to disk an obj file containing the paths of the

"10 fingers in space. Since you are tracking more than one object you cant use mcjTracer's

"Long Line" option, and are therefore limited to 256-steps-long paths.
