Description	The construction of a planar convex hull is an essential operation in computational geometry. It has been proven that the time complexity of an exact solution is $\\Omega(N log N)$. In this paper, we describe an algorithm with time complexity $O(N + k^2)$, where $k$ is parameter controlling the approximation quality. This is beneficial for applications processing a large number of points without necessity of an exact solution. A formula for upper bound of the approximation error is presented.
