Tangent vector fields (and their generalizations) play an important role in geometry processing applications, including texture synthesis, parametrization, deformation and remeshing. In this talk, I will present recent tools for computing these fields at interactive rates, while following user-defined directional constraints. Tangent vector fields enriched with additional properties have immediate practical applications: singularity-free fields can be used to digitally restore damaged historical documents, curl-free fields are gradients of global parametrizations, which can be designed in an intuitive and interactive way, and conjugate fields naturally represent planar tessellations, which are ideal to design glass and steel buildings.


Daniele Panozzo Daniele Panozzo is an Assistant Professor of Computer Science at the Courant Institute of Mathematical Sciences in New York University. Prior to joining NYU he was a postdoctoral researcher at ETH Zurich (2012-2015). He earned his PhD in Computer Science from the University of Genova (2012) and his doctoral thesis received the EUROGRAPHICS Award for Best PhD Thesis (2013). Daniele’s research interests are in digital fabrication, geometry processing, architectural geometry and discrete differential geometry. He received the EUROGRAPHICS Young Researcher Award in 2015 and his work has been covered by Swiss National Television and various national and international printed media. Daniele is leading the development of libigl, an award-winning (EUROGRAPHICS Symposium of Geometry Processing Software Award, 2015) open-source geometry processing library that supports academic and industrial research and practice.
