[ REQ 5272]: PSsnapshot in Geomview

[tad at sofya.umd.edu]

To whom it may concern:
	We are having difficulties with the PSsnaphot module in
Geomview.  In particular, we construct a polyghedron in 3D using
Mathematica and are viewing it through Geomview. However, whenever
we take a PSsnapshot of the polyhedron, the postscript file
is screwy i.e. intersecting polygons viewed from the camera in
Geomview become nonintersecting polygons in postscript.
	I am certainly willing to send you the Mathematica file
that generates these pictures. Or you could copy it from my
World Wide Web page "http://www.math.upenn.edu/~tad" under the
heading Papers and in the Crooked Planes announcement paragraph.
The offending command is

Show[Graphics3D[{nCrPl[{{2.,0.,1.},Zero}],
                nCrPl[{{-2.,0.,1.},{0.,-25.,0.}}]}  ]];

	Thank you for your attention to this matter.
