I'm looking for a 3-D plotting routine that will generate magnetic field lines using magnetic field vector data as input. The problem is analogous to that of plotting flow streamlines from velocity vector data. The input data would consist of Cartesian coordinate arrays x(i), y(j), z(k), and magnetic field component arrays Bx(i,j,k), By(i,j,k), Bz(i,j,k). The NCAR Graphics package has a 2-D routine called STRMLN that can plot field lines (streamlines), but no 3-D routine. Apparently, the IRIS system at NASA/Ames has a routine called PLOT3D that will do the trick, but I cannot access it easily, if at all. Does anyone know of any other 3-D routines that are available? Any ideas would be greatly appreciated.
