SUMMARY:Non-Traditional Modelling - Brian Wyvill\, University of Bath & Un
 iversity of Victoria
DTSTART:20140331T103000Z

CONTACT:Neil Dodgson
DESCRIPTION:Despite great advances in computer graphics\, it still takes m
 any hours to build detailed computer models.  The manufacturing industry i
 s entrenched in parametric models\, and the triangle mesh still dominates\
 , both as the subject of most modeling research\, and as a medium for cont
 ent creation for games and the movies. GPU hardware for processing and sca
 nning hardware for capture\, support the mesh modelling methodology over a
 ll else. \n\nIn this talk I will resurrect the idea of the nearly extinct 
 implicit modeling approach\, and claim that such a methodology has some ad
 vantages over current popular techniques. In this paradigm\, models are th
 ought of as solids and it is easy to produce aesthetically pleasing blends
  and detect when objects are in contact. Models are visualized as iso-surf
 aces in a scalar field\, where field values can be calculated from functio
 ns that consider both distance and gradient.\n\nThe talk will be illustrat
 ed by slides and video\, and the latest results on an application to skinn
 ing for implicit characters for games will be shown.  At the end of the ta
 lk a short demonstration of something entirely different to astound your f
 riends will be given.\n\nBio: Brian Wyvill graduated from the University o
 f Bradford\, UK\, with a PhD in computer graphics in 1975.  As a post-doc 
 he worked at the Royal College of Art and helped make some animated sequen
 ces for the _Alien_ movie.   He moved to Canada in 1981 where he has been 
 working in the area of implicit modeling\, sometimes with his brother Geof
 f Wyvill. He is also interested in sketch based modeling\, NPR and music\,
  and enjoys combining these areas of research. \n\nBrian spent a quarter o
 f century at the University of Calgary\, followed by seven years as a Prof
 essor and Canada Research Chair at the University of Victoria\, in British
  Columbia\, and is currently a professor in computer science at the Univer
 sity of Bath\, UK.\n
