David Park's DrawGraphics package, which costs a nominal fee, can help you do exactly what you want. I wrote some messy code that uses the package in this way, which you can see here: http://chris.chiasson.name/Engineering_Optimization/appendix.hw5.Sequential_Unconstrained_Minimization.html#fig.hw5.problem_5-4_constrained_objective_function http://chris.chiasson.name/Engineering_Optimization/chapter.hw3.Linear_Programming.html I'll eventually revise it, but I'm sure you wanted an answer yesterday. Maybe he will write you personally.
