Alexander Pasko’s areas of interest are geometric and heterogeneous volume modelling, computer-aided design and 3D printing, computer animation and computer art. His 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 modelling language called HyperFun (from Hyperdimensional Functions), which has extensive applications in education, computer animation, biology, digital fabrication, and other areas. The international R&D Digital Materialization Group lead by Alexander has published more than 130 papers in academic journals and conferences, and distributes its software under a special open source license.
