Dear Etienne,

thanks for your reply. Yes, I need access to the data points and the
faces (i.e. triangulations).

Sure, that's certainly an option; although it would be nice to have it
integrated in Octave. The The "best" solution is probably an
oct/mex-wrapper above the import functions of meshlab/vcglib [1,2].
These software support already a number of mesh-data formats.

Thanks for the updated vrml-package. vrml_browse is now working for me
(on Debian 8), unlike the package from octave-forge (missing freewrl),

It seems octave-vrml has been migrated to mercurial
  hg clone http://hg.code.sf.net/p/octave/vrml octave-vrml



Best,
  Alois
