What I meant by depth, is that is based on ones perception. As I may think something has more definition, another may feel is lacks it. Depth is an illusion, a trickery of light and shadowing. Of course something may actually have depth, it can very will have a 3D look to it with the right placing of said lights and shadowing. (Of course I still wish to make my 3D character)

I understand that Polygon modelings is commonly used in making lowres models, so then would I use nerbs if I was creating an animated video? I am teaching myself currently, reading reading reading... Anyways, I have read that nurbs can suffer from "tearing". So would it be advisable to use polygons rather than nurbs to make a 3d animation?
