SUMMARY:Representations of smooth surfaces for analysis and manufacture - 
 Dr Malcolm Sabin (DAMTP\, University of Cambridge)

CONTACT:Nami Norman
DESCRIPTION:For repeatable manufacture of objects with smooth aesthetic su
 rfaces\, it has always been necessary to have a representation acting as t
 he master\, so that the parts of the object will fit together properly.   
 In the latter half of the 20th century numerical techniques for the analys
 is of\, for example\, strength and stiffness required that the representat
 ions should be machine readable.   Numerically controlled production machi
 nery gave similar requirements.  \n\nThe talk describes half a dozen or so
  different representations which have been used\, including physical lofti
 ng\, NURBS\, STL files and subdivision surfaces\, summarising their essenc
 es\, strengths and weaknesses.\n
