Thanks for making your octave->geomview drivers available. You have
done some quite elaborate work to get this going!

It's a very long time since I looked at geomview (that earlier
version kept crashing ... ).

Certainly, this is a very good way of producing 3d curves and surfaces,
with the possibility of spinning them or "flying" round them to
explore their structure.

And, reading the geomview documentation, it seems that this also
offers the possibility of dynamic plotting, and also of passing
"mouse-clicks" back t octave, if one were to add the pipe/socket
mechanism.

One thing needs to be done, and I'm too little familiar with
geomview as yet to see how to do it nicely, which is the plotting
of isolated points (with different "markers"), rather than curves
or surfaces. If I understand it right, the only ways to do this
with geomview is either to construct a solid (of one shape or another)
around each point; or to plot a stream of vectors with coincident
endpoints.

However, a very good start, and what is already available is,
in its own way, very useful.

Ted.
