Towards Interactive Complex Implicit Modelling

Brian Wyvill (University of Victoria, Canada)

18/03/2008 - 9:30h / Sala de Videoconferência junto ao Centro de Congressos do Pavilhão de Civil (Alameda)

Resumo: The BlobTree structure is an extended CSG tree that combines a scene graph with nodes that relate skeletal implicit models, such as blending, CSG and deformations.
Recent work in sketch based modeling with implicit surfaces permits a user to rapidly prototype implicit models. In this talk, a new method for producing interactive implicit deformations is presented. Implicit models are volume models and do not contain a natural 2D surface parameterization. Two methods for mapping 2D textures will be presented, enabling texture decals to be placed on implicit and on any point based surface.

Brian Wyvill graduated from the University of 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 sequences for the Alien movie. He emigrated to Canada in 1981 where he has been working in the area of implicit modeling, sometimes with his brother Geoff Wyvill (University of Otago). He is also interested in sketch based modeling and NPR and enjoys combining these areas of research.
Brian recently took up an appointment as Professor and Canada Research Chair at the University of Victoria, British Columbia.
