[x3d-public] recovering/reconstructing NURBS diagrams in X3D Architecture specification

[Brutzman, Donald (Don) (CIV)]

We are performing final editorial review of Mantis issues collected over the
years.  Here is one that is still outstanding.

 

The following figures are pretty good but could be improved, particularly if
the original models were available somewhere.

 

Does anybody know where these are?  Alternatively might anyone want to
recreate or improve these figures?

This should be an interest little project if someone wants to pursue it.
Results will retain full credit and get faithfully saved/shared in the X3D
Examples Archives.

 

Thanks for considering this.  Have fun with X3D!

 

all the best, Don
