node_choose_least_enlargement() static int node_choose_least_enlargement ( const RTreeNode *  node, const STBox *  box, const RTree *  rtree  ) static Selects the child node that requires the least enlargement to accommodate a new STBox. This function iterates through the child nodes of a given RTree node to determine which child node's bounding box would need the least enlargement to include a new STBox. The function calculates the area of each node's bounding box before and after union with the new STBox and selects the one with the smallest area increase. Parameters [in] node Pointer to the RTreeNode structure containing the child nodes. [in] box Pointer to the STBox structure that is being inserted or considered. [in] rtree Pointer to the RTree structure, which provides the method for calculating areas. Returns The index of the child node that requires the least enlargement.
