“Ofir Weber’s Ph.D. thesis, in the field of geometry processing, describes novel and efficient methods for 2D and 3D shape manipulation. It is a rare combination of deep mathematical theory, based on complex analysis and harmonic theory, with efficient and robust implementations on modern GPU hardware. The thesis was done at Technion – Israel Institute of Technology. Detail preserving shape deformation is a topic with significant research activity in the last few years. In this very competitive area, Weber managed to propose groundbreaking advances, by a combined use of the right mathematical tools and efficient implementations. He described the generalization of barycentric coordinates by using Complex Analysis, leading to a very elegant formulation and a deeper understanding of the problem. The results described in the thesis have been published in high-ranking journals and conferences, including SIGGRAPH and Eurographics, where it also received a Best Paper Award. His work is also being considered for a US patent.”’][/simple_tooltip]
