node_sort_axis() static void node_sort_axis ( const RTree *  rtree, RTreeNode *  node, int  index, bool  upper  ) static Sorts STBoxes within an RTree node along a specified axis. This function initiates the sorting of STBoxes within a given RTree node using QuickSort. Parameters [in] rtree Pointer to the RTree structure, which provides the function for retrieving axis values. [in,out] node Pointer to the RTreeNode structure containing the STBoxes to be sorted. [in] index The axis index along which to sort the STBoxes. [in] upper Boolean flag indicating whether to sort by the upper or lower axis value.
