Recently in a series of articles, Barron, Goebel, and Jensen\cite{barron2012functions} \cite{barron2012quasiconvex}\cite{barron2013quasiconvex} \cite{barron2013uniqueness} have studied secondorder degenerate elliptic PDE and first order nonlocal PDEs for the quasiconvexenvelope. Quasiconvex functions are functions whose level sets are convex. ThePDE is difficult to solve. In this article we present an algorithm forcomputing the quasiconvex envelope (QCE) of a given function. The QCE operatoris a level set operator, so this algorithm gives a method to compute convexhull of sets represented by a level set functions. We present a nonlocal linesolver for the quasiconvex envelope (QCE), based on solving the one dimensionalproblem on lines. We find an explicit formula for the QCE of a function definedon a line.
