Only one edge is shown for QUADs under the following circumstances:
geomview run on a server, over X.
-- geomview 1.9.4 in the standard, updated Fedora Core 8 distribution (2.6.23.9-85.fc8, 86 athlon i386 GNU/Linux)
-- Accessed via PuTTY and Xming (32-bit) from Windows x64.
command > geomview -noopengl &
(openGL does not work with this setup).
Load csquare.quad.
Inspect Appearances.
Turn on Edges, turn off Faces, turn off BBoxes (BBoxes will mimic edges).
The same behavior shows with the following file loaded:
List is first line in file, } is last.
LIST
{ BBOX
-0.1 -0.1 -0.1
1.1 0.2 0.2
}
{ QUAD
0.0000 0.0000 0.0000
1.0000 0.0000 0.0000
1.0000 0.0000 0.100
0.0000 0.0000 0.100
}
{ QUAD
0.0000 0.0000 0.100
1.0000 0.0000 0.100
1.0000 0.1000 0.100
0.0000 0.1000 0.100
}
Also, if one of these files is loaded, unloaded, and the other file loaded, geomview crashes with a segmentation violation.
I will test this on a fc8 desktop with OpenGL.
