I have a notebook on the unfolding of the pitch fork bifurcation that you can download from http://www.higgins.ucdavis.edu/UCDMath/NLDApplications.php The notebook is called imperfect bifurcation The notebook shows how to plot the 3 dimensional surface (the catastrophe surface) that displays the unfolding of the bifurcation point.
