Symmetry is ubiquitous in nature and man-made artifacts. In this talk, I will first show how symmetry analysis and organization can play a crucial role in understanding a 3D shape in a hierarchical way. In particular, it may seem surprising that one can infer the generative history of a pattern by analyzing its symmetry alone. With an intimate connection between symmetry and functionality (e.g., symmetric parts in a 3D object tend to perform the same function), symmetry provides a first cue to understand object functionality, but the key missing piece is how an object interacts with its environment to perform its functions. In the second part of my talk, I will cover our recent works on functional understanding of 3D shapes, evolving from analyses in a static setting to inferring part motion from a single static snapshot.



Hao (Richard) Zhang is a full professor in the School of Computing Science at Simon Fraser University (SFU), Canada, where he directs the graphics (GrUVi) lab. He obtained his Ph.D. from the University of Toronto, MMath and BMath degrees from the University of Waterloo, all in computer science. Richard's research is in computer graphics with a focus on geometry modeling, shape analysis, 3D content creation, and computational design and fabrication. He has published more than 100 papers on these topics. He is an editor-in-chief of Computer Graphics Forum and has served on the program committees of all major computer graphics conferences including SIGGRAPH (+Asia), Eurographics, Symposium on Geometry Processing (SGP), among others, and is SIGGRAPH Asia 2014 course chair and a paper co-chair for SGP 2013 and Graphics Interface 2015. He received an NSERC DAS (Discovery Accelerator Supplement) Award in 2014, the Best Paper Award from SGP 2008, a Faculty of Applied Sciences (FAS) Research Excellence Award at SFU in 2014, an NFSC Outstanding Young Overseas Research Award in 2015, and is an IEEE Senior Member. For his university service, he recently won the SFU Dean of Graduate Studies Awards for Excellence in Leadership in 2016. He was a visiting professor at Stanford University in 2016-2017.
