I drew them (http://dl.dropbox.com/u/3778149/1crn_surface-points.jmol) and
notices that there are a lot of points in addition to the vertices of the
triangles that make up the surface. What are they? Can I get rid of them?
Is there a way to get only the vertices of a specific fragment?
What surface in terms of an 'isosurface' command do 'calculate SURFACEDISTANCE
FROM/WITHIN' use? Or is this based on some other calculation?
