Not meaning to be bold, but might I suggest we add any calibrated test
files to the WWW Viewer Test Page's VRML subsection...

http://www-dsed.llnl.gov/documents/WWWtest.html

We attempt to gather up files for testing purposes.
Not only does it test to make sure that the viewer is set up
correctly, it also allows the various authors to make sure that
there app works, to first order.

The present VRML test document that we have has numerous shapes
but they presently are not calibrated (i.e. doesn't tell the
user what the right answer should be).

Just thought I'd offer...
