Title: Pyramids, Tetris, Lego, and Spirals: New Geometry Problems for 3D Printing

Abstract:

Recent advances in 3D printing technologies have piqued the interests of the
computer graphics community, as the desire to improve efficiency and quality
of 3D fabrication is shedding new lights on several classic geometry problems
such as shape approximation, decomposition, and packing. In this talk, I will
cover several new geometry problems we have come across and tackled in
recent years that are strongly tied to 3D printing. However, what started our
initial investigation were often the intrigue and potential generality of the
geometry problems, beyond their specific applications to 3D printing. I will show
you how pyramid-like shapes, the Tetris game, Lego assemblies, and spirals, in
particular the lesser known Fermat spirals, all have interesting and surprising
connections to the geometry of 3D printing. It will be encouraging to see that
what we could offer are all first solutions and there is great room to improve.

Speaker bio:

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 is on sabbatical as a
visiting professor at Stanford University in 2016-2017.
