```  Hi Ole,

I am not sure I understand your question, but I can tell you a little bit about
the vrml_faces() function,
which may interest you: typical usage is

X = [x1 x2 ... xN; y1 y2 ... yN; z1 z2 ... zN]; ## Set of N points

F = [i1 i2 ..  iM; j1 j2 ... jM; k1 k2 ... kM]; ## Set of M triangular facets
## Facet 1 is X(:,i2),
X(:,j1), X(:,k1).

s = vrml_faces (X, F);                          ## VRML code (a string) to
display the facets

vrml_browse (s);                                ## Display the facets

Hth,

Etienne

# How can I do this by using Octave and vrml-packages at octave.sf.net?

# It would be nice to have som help or suggestions, if Octave with vrml can do
this.....
