Hello,

Let me tell what I have done with vtk before. Writing specific DLD
functions using vtk is not difficult. I have written a some small
functions for an old vtk version. (2D surfaces in 3D,...)

The first problem one gets is, the vtk function has its own loop and
waits for inputs (mouse or keyboard), so as long as the vtk window is
open the octave input is blocked.
I don't know how to solve this kind of problems. Could we merge the vtk
loop into octave's? Anyone with more insight?

The graphic classes for matlab are well documented and could be
reimplemented in octave, too. Of course, starting with a minimal set.
I.e. a figure class which holds a surface object and set, get
functions...

To get a start, I will rewrite my old functions next week, to show what
is possible.

Bye Kai
