Hi Mohammed, I'm guessing most of the community like me are rather perplexed by what specifically you are expecting/looking for. The "heights of a polygon" are simply it's z dimenion when you have a coordinate system with Z up like the OSG defaults. So setting it randomly would just entail setting the z value, but as your code show you already setting the xyz values then one would have to guess that this isn't what you mean at all. This leaves us rather stuck trying to guess what you actually mean. Mentioning extrusion doesn't help either as this rather tangential topic, or perhaps in your current view it's not. Alas we can't jump in your head and know what you are meaning.
The only thing I can say with certainly is to say that the OSG doesn't have an extrusion tool. The OSG is primarily a scene graph, not a scene building tool. Robert.
