The following plot was made using meshc.  It allows a curtain countour to be seen below the 3-D image.
The following plot was made using surfl.  It is a top view of the particle displacement.  You can see the path of travel of the two dipole sources out of phase 180 degrees:
The following plot was made using surfl.  It is a side view of the particle displacement.  You can see the two pulses in a 3-D projection out of phase by 180 degrees:
