Yeah.. how in this image they have the lines for the polygons.. and they have them diagramed in both planes.. and translated to show the topography of the face.. the highs and lows.

The pictures above are done so well that all the hard work is done from the diagrams -- the image plane references.

So any monkey can eyeball the vertices into place and line them up to create the model.

But I am wondering how they did that image so well.. either a lot of practice drawing those types of reference images or they actually sculpted it in real life and used that as a guide..

Sorry if I'm not making sense.. trying to explain this stuff is not easy. It's so abstract.. :headbang:
