compute_point_neighbors() [2/2] void pism::IceGrid::compute_point_neighbors ( double  X, double  Y, int &  i_left, int &  i_right, int &  j_bottom, int &  j_top  ) const Computes indices of grid points to the lower left and upper right from (X,Y). 3 2 o-------o | | | + | o-------o 0 1 If "+" is the point (X,Y), then (i_left, j_bottom) corresponds to point "0" and (i_right, j_top) corresponds to point "2". Does not check if the resulting indexes are in the current processor's domain. Ensures that computed indexes are within the grid. Definition at line 770 of file IceGrid.cc.
