If you create test.js with the following inside:

var testItem = "sphere.off";
main_window.open(testItem, 'off_plugin');
main_window.colorItems();
scene.item(0).setRgbColor(255,0,0);

and open the file with the Polyhedron demo you will see a red sphere 
(provided that you have sphere.off at the same location).

using "polyline_plugin" and maintaining yourself the item index you 
should be able to do what you want.

HTH,

Sebastien.
