1 Tamal Dey
A leader in the field of geometric computing, Tamal Dey has made several fundamental research contributions over the last twenty seven years in geometric modeling and surrounding areas. His research has advanced theoretical/practical understanding of several geometric/topological problems arising in application areas of science and engineering. Specifically, his work on surface reconstruction, mesh generation, and topological data analysis have found applications in geometric modeling, computer graphics, visualization, shape and data analysis. One of the hallmarks of Deys work is that he developed algorithms with theoretical guarantees that are useful in practice. An attestation to this claim is given by the fact that several software based on these algorithms have found wide use. The most widely used geometric library CGAL incorporates several of his results. The Cocone software developed by his group for surface reconstruction is widely used in academia and industry. His DelPSC software has been a basis for Synopsis to develop a new mesh generation software. He has written highly influential papers on a broad range of topics in geometric and topological computing, and has authored two books. The theoretical depth of his work is evidenced by his publications in top venues with 28 SoCG, 14 SODA, 3 ACM STOC, 2 IEEE FOCS, 2 JACM, 4 SICOMP papers, and the breadth by his 4 SIGGRAPH, 4 SGP, 5 IEEE Shape modeling, 3 Meshing Roundtable, 6 ACM-Solid Modeling, and 2 IEEE Visualization papers. Tamal was elected ACM Fellow in 2018.
2 Stefanie Hahmann
Stefanie Hahmann is a professor of computer science and applied mathematics at the University of Grenoble since 1995. She is a member of the research team Imagine, a joint team of LJK laboratory and INRIA. She graduated from Technical University Braunschweig and University Paris VI in mathematics in 1991. She obtained a PhD in Computer Science from Technical University Kaiserslautern (Germany) in 1994. Her research interests cover geometric modeling, design, and reconstruction. She contributed over the years to a number of high-level models for shapes and deformations such as G1 surface splines, volume preserving multiresolution deformation methods, and developable surfaces for animation. She has been recently focusing on expressive shape generation using sketch-based interfaces and immersive environments. Stefanie is very active in service to the community. She is associate editor of CAD and Computers & Graphics. Stefanie was conference chair and paper chair for many international conferences in the field of geometric modeling and computer aided geometric design. She also organized five Dagstuhl seminars on Geometric Modeling and was Program director and then Vice-chair of the SIAM activity group on Geometric Design (2009-2012). Stefanie was also very engaged in the Solid Modeling Association (SMA). She was not only paper chair for four SPM conferences in 2011, 2012, 2016 and 2017, but also served for five years as a member of the SMA Executive Committee from 2013 to 2017. She is conference co-chair of the present SPM 2019 conference.
3 Shi-Min Hu
Shi-Min Hu was elected as SMA Fellow for his long-term contributions to curve and surface modeling, 3D point cloud reconstruction, and geometric computing for image and video processing. His early work on curves and surfaces included editing curves and surfaces with geometric constraints, extension of curves and surfaces with maximal continuity, approximate degree reduction and approximate merging algorithm for curves and surfaces. In last ten years, he has worked on 3D reconstruction from point clouds, including automatic semantic modeling, real-time high-accuracy 3D reconstruction, and reconstruction from noisy and incomplete depth maps using 3D convolutional networks. Shi-Min is famous for his “Sketch2X” works, including Sketch2photo and Sketch2Scene, which use interactive sketching for internet image montage and 3D scene modeling. He also made solid contributions to applications of geometric computing in image and video processing. He showed how to do 3-sweeps for 3D modeling from a single photo, taking image editing to the third dimension. He proposed the global contrast method for salient region detection, and it is now one of the two main computational principles for salience detection, with great importance and influence in the field of computer vision. Besides serving as SMA Executive Committee Chair, he has also been very active in conference organization and journal editorship, as well as supervising many successful PhD students and postdocs, all of which further ensure his lasting contributions to our field.
