tboxnode_init() static void tboxnode_init ( TBox *  centroid, TboxNode *  nodebox  ) static Initialize the traversal value. In the beginning, we don't have any restrictions. We initialize the node box to cover the whole 4D space as follows left = TBOXFLOAT XT((-inf, +inf),(-inf, +inf)) right = TBOXFLOAT XT((-inf, +inf),(-inf, +inf))
