polylines or polygon edges


Is it possible to draw polylines in COLLADA, particularly polylines with certain thicknesses? (like in KML) Als is there perhaps a method to highlight the edges of polygons models or even triangles?

If yes, please post some keywords and/or URLS. Thanks in advance.


10mins later:
just found something about <lines>, it does not talk about attributes such a thicknesses. Or can this be done in materials?

The visual appearance of a <mesh> is described by the <material> bound to the primitives e.g <polylist>, <line>.
