In this tutorial, we'll cover a series of lessons to discuss some of the issues we face when dealing with the topology of our models. The topology or edge flow of our models is an important consideration for many reasons. Over the course of the these lessons, we'll look at how topology can affect the shape of our models. We'll looks at ways of finding and cleaning up n-gons and triangles. We'll also talk about how the topology affects smoothing and edges of our models, and how much animation and deformation depends on good topology. Many of the lessons in this tutorial were created to address specific issues students have had in dealing with the topology of their models, so hopefully you'll be able to pick up a few tips to add to your Modeler's Toolbox.
