VRML and Octave

  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

# I am having a VRML file of a vessel hull, let say x axis is along vessel, y is to left, and z is upwards.

# Origin is located at aft.

# I want to then to estimated the hull shape in Y-Z plane for different lengths.
# For x = 10, I will then have let say 10-20 coordinates (Y,Z), from the left side to the right side.
#
# 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.....
