[ REQ 6047]: Bug in geomview-1.6b

[harrison at cs.ubc.ca]

Hi,

We have a beta copy of Geomview 1.6b (via request 5906) and I've found
a bug that occurs when running Geomview on a Irix 6.2 machine but
using a Irix 5.3 machine for display purposes:
    Polygon faces of an OFF file don't display on the Irix 5.3
    display when Geomview runs on an Irix 6.2 machine.

If I run Geomview 1.5 on the 5.3 machine everything is fine.  If I run
Geomview 1.6b on the 6.2 machine and use either it's console display
or another 6.3 machine's display everything is fine.  Vectors, menus,
etc. all work fine, it is only the polygons that aren't displayed on
the 5.3 console when Geomview 1.6b runs on an Irix 6.2 machine.




The OFF file is:

OFF
9 8 0 # number of vertices, faces, and edges
# the vertices and normals
1.00  1.00  1.00  
1.00  1.50  1.00

2.00  1.50  1.00
