Parameterizing Surfaces and Computing Surface Normal Vectors

In this video we discuss parameterizing a surface. We use two approaches, a simple approach which models a surface using a level surface as well as a robust parameterization using two independent variables. We show how both formulations can be used to compute normal vectors to the surface at any given point on the surface.
