    A new Linear Time Algorithm for Computing the Convex Hull of a Simple Polygon in the Plane

    Export to Mendeley

    The problem of determining the convex hull of a simple polygon has received a lot of attention in the early eighties. The first linear time algorithm for this task proposed by Sklansky in [S72] was based on the simple idea of removing all left turns while moving around the polygon in clockwise orientation. This algorithm was shown to fail in some cases. Since then several correct, yet more complicated linear algorithms have been published and classes of polygons have been determined for which Sklansky's original algorithm can be used. In our note we show how to mend Sklansky's Algorithm in a simple way and prove the correctness of the resulting algorithm. As an application we show how to compute a rectangle of smallest area containing a given simple polygon in linear time. 1 Introduction The problem of determining the convex hull of a simple polygon has received a lot of attention in the early eighties.

    Title : A new Linear Time Algorithm for Computing the Convex Hull of a Simple Polygon in the Plane
    Abstract : The problem of determining the convex hull of a simple polygon has received a lot of attention in the early eighties. The first linear time algorithm for this task proposed by Sklansky in [S72] was based on the simple idea of removing all left turns while moving around the polygon in clockwise orientation. This algorithm was shown to fail in some cases. Since then several correct, yet more complicated linear algorithms have been published and classes of polygons have been determined for which Sklansky's original algorithm can be used. In our note we show how to mend Sklansky's Algorithm in a simple way and prove the correctness of the resulting algorithm. As an application we show how to compute a rectangle of smallest area containing a given simple polygon in linear time. 1 Introduction The problem of determining the convex hull of a simple polygon has received a lot of attention in the early eighties.
