We don't have much of an OFF viewer that runs on a PC, but you could
pick up a copy of geomview that just sends bitmaps to the X display:
it's at
   ftp://geom.umn.edu/priv/slevy/gvx-161p9e-sgi.tar.gz

and contains two executables, which should be extracted in your
geomview installation directory (e.g. /usr/local/Geomview):
   bin/sgi/gvx		The standard geomview executable (with some bugs fixed)
   bin/sgi/gvx.MESA	geomview executable using MESA OpenGL-like library,
			   which should work with any X server.

You'd be able to make the MESA version be the default by
  setenv GEOMVIEW_GVX  /usr/local/Geomview/bin/sgi/gvx.MESA

and then running geomview.

Another possibility: I'm told that some commercial Windows X servers
do support the GLX extension.  This would take advantage of 3D graphics
acceleration hardware on the PC, and even without it, would probably
run faster than sending images over the network.
One of these commercial X servers is described at
