Team Origami: Computer Graphics and Geometry Processing

Coordinator : Nicolas BonneelAssistant coordinator : Florence ZaraTeam 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.

  • 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.
