Eurographics Outstanding Technical Contributions Award 2019:Niloy Mitra

Niloy Mitra is a Professor in the Department of Computer Sci-ence at University College in London where he leads the Smart Ge-ometry Processing Group. He received his Bachelor’s degree fromIIT Kharagpur, and his Master’s and PhD degrees from StanfordUniversity. Before establishing his position at UCL in 2011, he wasa postdoctoral scholar at TU Vienna, and an assistant professor atIIT Delhi and KAUST.

Niloy has an extraordinary record of outstanding research con-tributions in the areas of shape analysis, data-driven geometry pro-cessing, and computational fabrication. In recognition of his re-search, he has received the ACM SIGGRAPH Significant New Re-searcher Award for “his outstanding work in discovery and use ofstructure and function in 3D objects” in 2013, and the BCS RogerNeedham award in 2015 for “distinguished research contribution incomputer science”. His work has been funded by an ERC StartingGrant on SmartGeometry, ERC Proof-of-Concept Grant, a GoogleFaculty Fellowship, and was twice featured as research highlightsin the Communications of the ACM.

Niloy’s research spans a range of problems focused around rep-resenting, analyzing, processing, fabricating, and editing 3D shapesfor computer graphics applications. He has contributed widely usedalgorithms on fundamental aspects such as normal estimation innoisy data, geometry completion, and local and global shape align-ment. As an example, his technique for surface registration basedon 4-point congruent sets has introduced a highly original ap-proach to the problem of shape registration and been establishedas a standard approach in many practical scenarios. He further pi-

oneered research on symmetry and structural regularity detectionin 3D objects, contributing several algorithms that have becomebuilding blocks for a variety of applications. This work inspiredstructure-aware geometry processing, an entire subfield in 3D ge-ometry processing that is concerned with detecting and exploitingregular structures in 3D shapes to address various problems, in-cluding shape registration, completion, manipulation, and recon-struction. A further core theme in Niloy’s work is the problem ofrepresenting entire shape collections in order to support operationssuch as interactive modeling, shape space exploration, and analysisincluding classification, segmentation, and functionality detection.He has broken new ground in this area by introducing a numberof highly innovative problem statements and proposing creativeand sophisticated data-driven solutions. His work showed how toleverage novel shape representations and algorithms in a numberof applications, for example to explore shape collections that fulfillphysical constraints, ensure that they can be fabricated, provide anintended functionality, or synthesize new editable geometric con-tent. Niloy’s work undoubtedly has made an extraordinary impactin the academic research community and in industry. He has beengranted several patents, and his academic publications appear reg-ularly in the top journals and conferences in the field, receivingthousands of citations every year.

In addition, Niloy has provided outstanding service to the re-search community. He has served as the SIGGRAPH Asia CourseChair in 2016, as the conference chair for Advances in Architec-tural Geometry (AAG), the SIGGRAPH Asia Workshop on IndoorScene Understanding both in 2014, and Symposium of GeometryProcessing in 2017. He has been program chair for several confer-ences such as Geometric Modeling and Processing 2019, PacificGraphics 2015, Symposium on Geometry Processing 2012, andShape Modeling International 2011. In addition, he has served asan associate editor for ACM Transactions on Graphics, ComputerGraphics Forum, IEEE Transactions on Visualization and Com-puter Graphics, the Visual Computer, and Computers & Graphics,not to mention the dozens of conference program committees hehas participated in. Finally, he is in high demand as a speaker forconference keynotes and invited talks, including keynotes at the Eu-rographics, the Symposium on Geometry Processing, Vision, Mod-eling, and Visualization conference, ACM CAD/Graphics, and Pa-cific Graphics.

Eurographics is extremely pleased to recognize Niloy Mitra withthe 2019 Outstanding Technical Contributions Award.

The PhDthesis entitled “Connections, Changes, and Cubes: Unfolding Dy-namic Networks for Visual Exploration” got an honorable men-tion at the IEEE VGTC VPG Doctoral Dissertation Award. In 2015Benjamin was visiting researcher at the University of Washingtonand Microsoft Research. He has been a PostDoc at Harvard Univer-sity (Visual Computing Group), Monash University, as well as theMicrosoft-Research INRIA Joint Centre. In 2017 Benjamin joinedthe University of Edinburgh where he is currently a Lecturer in De-sign Informatics and Visualization.

Benjamin’s research designs and investigates interactive infor-mation visualization interfaces to help people explore, communi-cate, and understand data. His research in information visualiza-tion is very broad and encompasses network visualization, visual-ization of spatio-temporal data, data-driven storytelling, visualiza-tion in augmented and virtual reality (immersive analytics), non-digital visualization, and teaching and learning visualization. Hisinfluential and very original contributions include novel visualiza-tion strategies either for specific data (dynamic networks), usingnovel narrative strategies (data-driven storytelling, data comics), orusing advanced display hardware (AR/VR). He is producing ex-cellent research that is backed up with user studies. Recently Ben-jamin involves himself intensively in applying comics to tell storiesabout data. Comics are an entertaining and familiar medium, whereBenjamin is strongly contributing to enable visualization author-ing tools to leverage the expressive power of this communicationchannel, e.g., designing comic storyboarding tools for presentingdynamic networks.

Benjamin is publishing at an impressive rate, for example withthree IEEE TVCG papers in both 2017 and 2018, and one alreadyin 2019. He is also strongly present in the HCI community, for ex-

ample with several contributions at CHI 2019. Many of his verywell cited papers are published in IEEE TVCG, EuroVis, ComputerGraphics Forum, and CHI. He is active and highly visible in ourand neighboring research communities, for example as ACM CHIPaper Associate Chair, IEEE InfoVis Program Committee member,IEEE VAST Program Committee member, and TransImage Con-ference Co-chair, all in 2018.

A research highlight of Benjamin’s career is the 2018 CapitalGrant from the UK Engineering and Physical Sciences ResearchCouncil (EPSRC) “VisHub: A Collaborative Data VisualizationSpace for Interdisciplinary Research, Teaching, and Public Engage-ment”. He has already received various awards for his innovativeresearch work. He is internationally very well connected and pub-lishes with a wide variety of top experts in the field.

Computational and Data-Driven Design for Manufacturing

Bernd Bickel

Head of the Computer Graphics and Digital Fabrication GroupInstitute of Science and Technology Austria (IST Austria).(https://ist.ac.at/research/research-groups/bickel-group/)

Abstract

Advanced fabrication techniques have grown in sophistication overthe last decade, vastly extending the scope of structures and mate-rials that can be fabricated. While new opportunities have emergedfor the manufacturing of customized shapes, architected materialswith novel functionalities, and active composites that can sense andrespond to their environment, their potential impact is limited bythe lack of efficient computational approaches for design.

In this talk, I will describe the recent progress in computationalfabrication toward novel concepts for modeling, designing, and re-producing objects with nontrivial shapes, topologies, and function-alities. I will reflect on the successes and challenges of computa-tional fabrication and discuss opportunities for further work in thisarea.

Predictive Simulation for Films, Fashion, and Physics

Florence Bertails-Descoubes

Head of the modELisation de l’Apparence des phénomènes Non-linéaires (ELAN) teamINRIA Grenoble Rhône-Alpes / LJK

Abstract

In the last decades, physics-based simulation in Computer Graphicshas become instrumental in capturing fascinating mechanical phe-nomena such as cloth folding, ribbon coiling, plant growth, granu-lar flowing, or hair entangling. Complex simulations not only en-rich the visual appearance of animations in feature films, but alsogive the hope in the near future to quickly prototype challengingsystems involving post-buckling or collective behaviors, such asvirtual garment and hairstyle try-on systems. In soft matter physics,simulation is also on its ways to becoming a fundamental tool forimproving our understanding of physical phenomena unexploredso far, and for designing new materials with controlled properties.

In this talk I will show that although building a simulator that isboth predictive and scalable remains an open challenge, advancestowards this goal can be made possible thanks to a pluridisci-plinary modeling approach combining skills across Mechanics andPhysics, Applied Mathematics, and Computer Science.
