Not being a physics type, I am not sure just what he is up to. He seems to
be more interested in raytracing than rendering. His goal is to improve the
calibration of sensor data correction programs, not the sensors themselves.

Eventually want to work with a native windows version. Started with cygwin
since that seemed to be what the documentation called for. This lets me
establish a baseline.

Managed to get startxwin.bat running. Had to modify one line at the top due
to the way cygwin is installed: SET CYGWIN_ROOT=C:\program_files\cygwin.

The xwindow came up with a cygwin prompt. In the pyxrsclient directory,
entered the following command: python pyxrsclient.py +Iwoodbox.pov +V +W800
+H600 +L/cygdrive/c/program_files/cygwin/tmp/povray-3.6.1/include. The
povray parameters are the ones used in successful povray and megapov tests.

Received the following error message (had to type it in so I hope it is
correctly presented:

Traceback (most recent call last):
File "pyxrsclient.py", line 877 in ?
g_num_x_tiles = g_parser.getImgWidth() / g_parser.getBlockSize()
File "pyxrsclient.py", line 131, in getImgWidth
imgwidth = int(re.search("(?<=[+-]w)[0-9]+", self.cmd).group(0))
AttributeError: 'NoneType' object has no attribute 'group'
