You see triangles used a lot in creating shapes/meshes in computer graphics? Why is this used over say squares/pentagons or other shapes? Do they conform better to the shape/mesh?
It was mentioned that there are a couple of reasons why triangles are used. Some of them are that it can essentially form any other n-gon and is the smallest n-gon.
I believe that we'll also mention quad meshes later in the course, but Kevin is exactly correct as to why triangles are used!
