Here I have for you two versions of the same perspective view. Taken from above and to the left. That crumpled mesh in the upper left is the group of mountains which appear on the right when you view the House from front and center. The little ground-level tower at front left of the House looks darker because it's mesh has been subdivided many times, an S mesh or Smesh. This makes the object look smoother and rounder, without any sharp, or even any flat, areas.

The shaded working models. These models are gray until I assign some kind of material (color, texture, etc). They also show whether the mesh has been smoothed or smeshed.
