[ REQ 5671]: geomview

[nkm93el at soton.ac.uk]

I am trying to use geomview to display a vector field using arrows. The arrows are all defined in an OFF file.

The manual says that polygons can be concave, but it doesn't seem to display them correctly. For example this file for 1 arrow:

OFF
7 1 7
0.035486 1.106457 0
-0.035486 1.106457 0
-0.035486 0.929029 0
-0.106457 0.929029 0
0.000000 0.822572 0
0.106457 0.929029 0
0.035486 0.929029 0

7 0 1 2 3 4 5 6 1.0 1.0 1.0 1.0

Using the X11 version of geomview, the second to last line draws okay when just displaying the edges, but the when using the face as well the line becomes horrizontal. I can't work out if its me or a bug in the program. can you help please?
