Web@Jason The Tissot indicatrix is nothing other than a pictorial representation of the derivative of the projection applied to a circle in the tangent plane at a point. The simplest way to draw it, then, is to compute this derivative (it's a 2 by 2 matrix A), parameterize the circle, and apply the derivative to the parameterized vertices. Voila ...
