One of the common algorithms for doing what you are asking has been
implemented by Fred Richards (Yale) in a program called ACCESS.  This is
the de facto standard for calculating protein solvent accessible surface
areas.  You can obtain ACCESS by contacting Patrick Fleming at:
fleming - at - cs.yale.edu.

Pat has ported the VAX code to Unix.
