octaviz without render window

[Lieven Theys]

Dear all,

I am a long time user of (basic) functions of octave.
I am running GNU Octave, version 2.1.73 (powerpc-unknown-linux-gnu).

Now I have run into a small problem.

I have been using gnuplot and its low and high level plot commands in  
octave to generate png and eps files through a web interface.

Up to here no problem. but ...

I am looking at switching to octaviz for my 3d plotting needs but I  
am not able to figure out how I can generate a file (png and/or eps)  
without having a render window showing up.

Can anybody point me in the right direction?

Kind regards,

Lieven
