Hi Tamara,
Thanks for your promt response,
I am having difficulty in loading the OFF file that I have generated. Is it
expecting a different format?
Thanks,

<p>You can do it by starting up Geomview with the right GCL (Geomview
<br>command language) file. Here's an example file, which I called
<br>"doit.gcl":
<p>----------
<br>(progn

<br>}
<br>)
<br>(redraw c0)
<br>(draw c0)
<br>(snapshot c0 /tmp/foo.ps ps)
<br>(exit)
<br>)
<br>----------
<p>You can see that I loaded some geometry and a camera which has a
<br>specific viewpoint, then I tell Geomview to draw the camera and take
a
<br>PostScript snapshot. Finally, the script tells Geomview to exit.
<p>Then just type at the command prompt
<p>% geomview -c doit.gcl
<p>a window flashes up on the screen, the snapshot happens, and Geomview
<br>exits.
<p>The way I got the camera specification was by interactively moving the
<br>camera to the position I wanted it in a previous session, then saving
<br>the camera specification, including it in the GCL file, and inserting
<br>the camera id "c0" in between "(camera " and the rest of the
<br>specification. (You can save the camera spec by hitting ">" in an
<br>interactive session, changing the default "Commands" to "Camera",
<br>change "World" to "targetcam", and give a filename in the browser or
<br>"-" to print it to stdout on your shell.
<p>Hope this helps,
