Understanding polygon-based models

In ZBrush, as well as many other 3D programs, polygons and vertices are the basic building blocks of models. Models made up of polygons are called polymeshes. Understanding what they are and how ZBrush deals with them will help you make sense of ZBrush's workflow. Let's double-click on the Dog project to open this up. So one thing I want to do is make the polygons that make up this mesh really clear, so I'm going to hit Shift+F. This turns on a mode called PolyFrame. It just makes it really easy to see where the edges of polygons are. Now if I go in to do any sculpting on this model, what you can see really easily is that the brush is only affecting the vertices, and the vertices are the corners of polygons.

So you can see that everywhere I move the brush, each vertex is highlighted, and right now the polygon mesh doesn't really have enough density to make any fine details, so it's just making these very big, crude, lumpy changes. If I want to sculpt finer details int...
