Example 36 with GeographyPointValue

use of org.voltdb.types.GeographyPointValue in project voltdb by VoltDB.

the class PolygonFactory method CreateStar.

/**
     * Create a star-shaped polygon with an optional hole.  This polygon will have
     * numPointsInStar outer points, and numPointsInStar inner points.  For each
     * outer point, OP, distance(center, OP) = distance(center, firstVertex).  For
     * each inner point, IP, distance(center, IP) = ratioOfPointLength*distance(center, firstVertex).
     *
     * If sizeOfHole is positive, then there is a hole with inner and outer vertices, as
     * with the exterior shell.  For each hole exterior point, HEP,
     *     distance(center, HEP) = sizeOfHole*distance(center, firstVertex).  For each
     * hole interior point, HIP,
     *     distance(center, HIP) = sizeOfHole*rationOfPointLength*distance(center, firstVertex).
     * So, the hole is equal to the exterior shell scaled by the number sizeOfHole.
     *
     * Note that this polygon will be symmetric around any line through the center and
     * an outer or inner point.  Consequently, the centroid of the generated polygon
     * must be the center.
     *
     * @param center The center of the polygon.
     * @param firstVertex The first vertex.
     * @param numPointsInStar The number of exterior points in the star.
     * @param ratioOfPointLength The outer/inner scale factor.  This must be in the range (0,1].
     * @param sizeOfHole The scale factor for the hole.  This must be in the range [0,1).
     * @return
     * @throws IllegalArgumentException
