DESCRIPTION:If building something needs more than one person involved\, th
 ere needs to be a way they can talk to each other about what shape is to b
 e built. Nowadays we have to talk to software for graphic rendering of ima
 ges\, analysis of performance and automated manufacture\, and the language
  we use to describe shape really has to be unambiguous.\n\nThe talk takes 
 the example of smooth shapes ( examples include boats\, cars and aircraft)
  and outlines the methods for defining them used over the last century\, h
 ow they developed with the increasing amounts of computer power available\
 , and the reasons why some representations  have superseded others and bec
 ome accepted as standards.\n\nMalcolm Sabin developed one of the first sur
 face representation systems using parametric surfaces when at Vickers Arms
 trongs (Aircraft) Ltd. in the late 1960's and early 1970's. He then spent 
 half a year at the Hungarian Academy of Sciences and three years at Kongsb
 erg Data Systems writing code inside a controller for numerically controll
 ed machine tools. He was then head-hunted to support a panel advising Depa
 rtment of Industry and the Science and Engineering Research Council on fun
 ding of Computer Aided Engineering.  The DoI connection disappeared after 
 three years\, but he continued advising the SERC through its ACME director
 ate until the mid 90s. He has worked with FEGS Ltd. on pre- and  post-proc
 essing of finite element meshes.  In the mid 90's he set up Numerical Geom
 etry Ltd. doing little bits of consulting\, but has also had close links w
 ith first DAMTP (Mike Powell's numerical analysis group) \, the Computer L
 ab (Neil Dodgson's Rainbow Group) and now the Engineering Department (Fehm
 i Cirak's group). He was awarded the Bezier Award in 2010 and the IMA gold
  medal in 2012 for his work in shape representations.\n
