 Hi Alois,

indeed, an import function would be nice. But I'm not familliar w/ vcglib or meshlab (and I haven't practice octfiles for years), so I don't think I'll wrap them in the vrml package anytime soon.

Dear Etienne,

thanks for your reply. Yes, I need access to the data points and the
faces (i.e. triangulations).
* A simple file filter (e.g. perl) may help you get some data out of a file.
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.

Good luck, Etienne PS: If you use the vrml package, you may prefer the one attached, which works better w/ new Octaves. On Debian/Ubuntu, you may want to apt-get install view3dscene and vrml_set_browser("view3dscene"). I'd submit these changes to octave-forge, but after RTFM a little, I haven't figured out how to submit patches :-(
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 octave-vrml
