box_area() static double box_area ( const RTree *  rtree, const void *  box  ) static Return the length, area, or volume of a bounding box. The function iterates over all dimensions defined in the RTree multiplying the lengths of the box along each axis Parameters [in] rtree Pointer to the RTree structure, which provides the number of dimensions and the method for retrieving axis lengths [in] box Pointer to the bounding box
