Dear Andrei,
Do you need any specific feature from VRML? If not, and you simply need
to import the mesh into Blender, you can do this:
1) Convert the mesh to ASCII format:
/mris_convert somesurface somesurface.asc/
2) Save the attached script somewhere, make it executable with chmod,
then use it to convert to Wavefront format, like this:
/./srf2obj somesurface.asc > somesurface.obj/
The script uses gawk (GNU awk), so make sure you have it on it's usual
location, /usr/bin/gawk on most Linuxes. If different, e.g. on Mac with
MacPorts or Fink, you may edit the first line to point the script to the
correct location. Not sure if it will work with other awk
implementations. Also, note that the output goes to stdout, so you
really need the ">", as in the example above.
Hope this helps!
All the best,
Anderson

Greetings, I have problems exporting the surface data in VRML format.
When I load the resulting .wrl file into Blender (a 3D modeling tool),
the resulting surface is full of holes (bad/missing polygons) and
connectivity of vertices is all wrong -- I see edges where they are
not supposed to be. Is is a common problem with VRML export? I used
"write_vrml 1" command, tksurfer version 5.
Any help will be greatly appreciated.
Cheers,
Andrei
