So why do we want the "good" triangles if they sometimes can be less efficient than long and skinny triangles?

@hii Here's a link to the paper referenced at the bottom of this slide. Even though long & skinny triangles may provide a good geometric approximation to a mesh, performing any computations on the same mesh could result in nasty problems. The previous slide gives a good example of this, where the area of the cylinder is poorly approximated by its triangle mesh.
