As mentioned previously, the URL http://www.eecs.wsu.edu/~schneidj/Animations/ provides all the code discussed in this paper. Additionally, FDTD code is provided to illustrate the use of these routines. The Internet sites listed below are also linked to this page.
The entire suite of pbmplus routines is available from a number of sites (via anonymous ftp) including ftp.x.org from the directory R5contrib. The netpbm routines provides a superset of the functionality provided by the pbmplus routines and can also be obtained from the same location.
The ImageMagick routines can be obtained from
http://www.wizards.dupont.com/cristy/ImageMagick.html.
The mpeg_encode utility is available via anonymous ftp
from mm-ftp.cs.berkeley.edu in the directory
pub/multimedia/mpeg/encode while the mpeg_play
utility is found in the directory
pub/multimedia/mpeg/play. Additional MPEG information can be
obtained from
http://www.arc.umn.edu/GVL/Software/mpeg.html and
http://www.eit.com/techinfo/mpeg/mpeg.html.
The commercial packages MATLAB and Mathematica, though not strictly graphics packages, provide a broad range of plotting tools. More information can be obtained from: http://www.mathworks.com/ and http://www.wri.com/.
The commercial packages IDL and PV-WAVE share a common ancestry
but have, for some time now, been developed independently. More
information about these graphics packages can be obtained from
http://www.rsinc.com/idl/ and
http://doc.boulder.vni.com/pvwave.dir/wavehome.html. AVS
produces another powerful commercial package that can be found
described at
http://www.avs.com/. Additionally, NAG
produces the Explorer graphics package that is described at
http://www.nag.co.uk:70/1h/Welcome_IEC.
VTK and Khoros are also powerful graphics packages. But, unlike the
previously mentioned packages, these can be obtained for free by
individuals (although some restriction may apply---please see the
appropriate licensing agreements). The relevant URL's are
