  • Method Details

    • addGeometry

      void addGeometry(Geometry geometry)
      Adds a geometry to the current bounding geometry using an incremental algorithm for dynamic insertion.
      Parameters:
      geometry - The geometry to add to the bounding geometry.

    • getBoundingGeometry

      Geometry getBoundingGeometry()
      Gets the current bounding geometry. Returns a Geometry.

    • construct

      static Geometry construct(MultiVertexGeometry mvg)
      Static method to construct the convex hull of a Multi_vertex_geometry. Returns a Geometry. \param mvg The geometry used to create the convex hull.

    • construct

      static int construct(Point2D[] points, int count, int[] out_convex_hull)
      Static method to construct the convex hull from an array of points. The out_convex_hull array will be populated with the subset of index positions which contribute to the convex hull. Returns the number of points in the convex hull. \param points The points used to create the convex hull. \param count The number of points in the input Point2D array. \param out_convex_hull An index array allocated by the user at least as big as the size of the input points array.

    • isPathConvex

      static boolean isPathConvex(MultiPath multi_path, int path_index, ProgressTracker progress_tracker)
      Returns true if the given path of the input MultiPath is convex. Returns false otherwise. \param multi_path The MultiPath to check if the path is convex. \param path_index The path of the MultiPath to check if its convex.
