Thursday, 16 March 2017, 2:30pm,  Prof. Alla Sheffer from University of British Columbia will be visiting CNR IMATI Genoa, and will give the following seminar

"CONVEYING AND ANALYZING SHAPES: FROM ART TO SCIENCE”

ABSTRACT: Humans have developed multiple ways to communicate about both tangible and abstract shape properties. Artists and designers can quickly and effectively convey complex shapes to a broad audience using traditional mediums such as paper, while both experts and the general public can analyze and agree on intangible shape properties such as style or aesthetics. While perception research provides some clues as to the mental processes involved, concrete and quantifiable explanations of this process are still lacking.

Our recent line of research aims to quantify the geometric properties and tools involved in shape communication and analysis, and to develop algorithms that successfully replicate human abilities in this domain. In my talk I will survey our efforts in this domain describing methods for creation of 3D looking shaded production drawings from concept sketches; sketch based modeling algorithms that automatically create complex 3D shapes from artist-generated line drawings in a range of domains, including industrial design, character modeling, and garment design; and methods for style analysis and transfer for both engineered shapes and garments. The common thread in these approaches is the use of insights derived from perception and design literature combined with subsequent perceptual validation via a range of user studies.

BIO: Alla Sheffer is a professor of Computer Science at the University of British Columbia. She investigates algorithms for geometry processing focusing on computer  graphics applications. She is particularly interested in geometric  interpretation of designer intent when conveying shape. Alla regularly publishes at selective computer graphics venues such as SIGGRAPH and SIGGRAPH Asia. Alla holds  5 recent patents on methods for shape communication and hexahedral mesh generation. She received an IBM faculty
award, Killam Research Fellowship, NSERC DAS, NSERC I2I, and the Audi Production Award. She served on the PCs for SIGGRAPH, SIGGRAPH Asia, Eurographics, and other key graphics conferences; co-chaired the PCs for SGP'06, Sketches & Posters at SIGGRAPH Asia'10, and IEEE SMI'13 and will co-chair the PC for Eurographics'18. She served on the editorial boards of ACM TOG, IEEE TVCG, Computer Graphics Form, Graphical Models, Computers & Graphics, and CAGD.
