New link to physics examples that include falling drops, by Lenore Horner.

An STL-to-faces converter by Derek Lura and me. STL is a simple file 
format for describing an object in terms of triangles and faces, very 
similar to the format for faces. There are both text and binary 
versions, and this converter handles both. Included in the package are a 
couple of STL files, including one made by Derek. The converter is 
structured in such a way as to be usable as an importable module, or if 
you run it directly it gives a file dialog box to view the two models 
included in the package, or other models you might find or create. Be 
sure to rotate the view to see all aspects of the models.

It is thanks to Derek's interest in this that got me wondering about 
thinking about smoothing algorithms, one of which has been implemented 
in the new VPython 5.2.

STL stands for "stereographic lithography" and is apparently used in 
industry for simple characterization of 3D parts.
