Team Origami: Computer Graphics and Geometry Processing

Coordinator : Florence ZaraAssistant coordinator : Adrien PeytavieTeam presentation document (PDF)
Team dedicated web site

Origami is a team dedicated to computer graphics and widely covers this field of study, and in particular via three main topics : geometry, rendering and simulation. In geometry, we develop algorithms to analyze and create meshes, point clouds, digital surfaces and procedural shapes for virtual worlds. In rendering, we are interested in challenges related to light simulation, sampling, virtual reality and perception. Finally, in simulation, we develop deformation and fluid models, and their discretization.

This team is the fusion of three teams: M2Disco, Ream, Geomod.

  • Eurographics 2024 best paper award in the Origami team
    At the Eurographics 2024 conference, a major event in computer graphics held in Limassol, Cyprus from April 22nd to 26th, the Günter Enderle Prize for the best paper was awarded to the work conducted by Baptiste Genest (Claude Bernard Lyon 1 University, LIRIS UMR 5205), Nicolas Courty (University of Southern Brittany, IRISA UMR 6074), and David Coeurjolly (CNRS, LIRIS UMR 5205). The title of their study is "Non-Euclidean Sliced Optimal Transport Sampling," aiming to extend point sampling strategies on non-Euclidean manifolds through optimal transport by slicing.

  • Liris researchers and engineers participate in the “Sciences, a women’s profession” day
    On March 8, 2024, the 8th edition of the “Sciences, a profession for women” day was held at ENS Lyon. This day is an opportunity to welcome high school girls from the Rhône Alpes region and introduce them to the full range of science and research careers. Liris researchers and engineers were "role models" for groups of high school girls and then welcomed them to the liris.

  • LIRIS at YGGDRASIL: the festival of imaginary worlds and the future
    As part of the "Collège d'Ingénierie" program, the ORIGAMI team from LIRIS (ENISE campus) was present at the "Demain, mais en mieux!" area of the YGGDRASIL festival at Eurexpo on February 3 and 4. As part of the "speed-searching" and a demonstration alveolus, members offered spectators the chance to embark on a multisensory virtual reality experience based around the medieval construction site of the Château de Guédelon.
