The objective of this workshop is to have an overview of the different disciplinary fields around the appearance of materials, surfaces and objects: materials, nanosciences, optics, image, computer science, metrology, perception, art and design, focusing on characterization by measurement, prediction by modelling, virtual prototyping, manufacturing and reproduction of objects with visual effects.

Access

The workshop will take place at the auditorium of Pierre et Marie Curie Campus, Sorbonne University.

Subway lines 7 or 10, stop Jussieu (see Subway map).  The subway entrance is just in front of the entrance of the campus, then the auditorium is on your right hand (see map below).
