Procedural multi-material modelling and 3D printing with scalar fields

Synopsis:
Emerging multi-material 3D printers and bio-printers have posed serious problems to existing Computer-Aided Design and other 3D modelling systems. For example, gradually changing materials and nested multi-level microstructures cannot be practically designed with existing methods and tools based on surfaces. An alternative approach employing scalar fields for the geometry representation can be easily extended to represent multiple spatially varying materials and complex microstructures inside the volumes. A short survey of existing methods in this area and examples of modelled and 3D printed objects will be given in the talk.
Biography:
Alexander Pasko is a professor at The National Centre for Computer Animation, Bournemouth University, UK. He received his PhD from Moscow Engineering Physics Institute (MEPI) in Russia in 1988, where he was a senior scientist until 1992. He was an assistant professor at the department of computer software, University of Aizu, Japan (from 1993 to 2000); associate and full professor at the Faculty of Computer and Information Sciences of the Hosei University in Tokyo, Japan (2000-2007).
Alexander Pasko's main research interest is development of a high-level universal model for spatio-temporal objects and phenomena with their internal properties. The model called the Function Representation (FRep) is based on the most universal mathematical language of real functions of point coordinates in geometric spaces. To support the mathematical concepts of this model, Alexander and his colleagues introduced and develop the special-purpose modeling language called HyperFun (from Hyperdimensional Functions), which has extensive applications in education, computer animation, biology, digital fabrication, and other areas. The international R&D HyperFun group has published more than 120 papers in academic journals and conferences, and distributes its software under a special open source license.
