Our workshop on the measurement of sparkle will be 5 November 2019 in Espoo (9 am – 5 pm). The BiRD progress meeting will be on 6 November 2019 (9 am – 3 pm).
Please, save the date in your agenda.
The presentations and minutes have been uploaded on the project website, in the stakeholder area.
Our workshop on visual appearance will be held at the University of Alicante in Spain on 29 May 2019.
The next progress meeting of BiRD will be held at CNAM, in La Plaine St Denis (FR), 21st May (9 am – 5 pm) to 22nd May (9 am – 12 am). Please, save the date in your agenda. If you plan to attend the meeting and have not registered yet, please contact us by email.
Following topics will be discussed :
– Progress on BRDF recommandations
– BRDF data file format proposal
– Measurement of Gloss
– Measurement of Sparkle
Details will be also given about BxDiff, our new project on BTDF & BSSRDF measurement and modelling, multiscale traceability, speckle and polarisation issues on BRDF. We will also have a breakout session to get your feedback, needs and remarks. And of course, coffee breaks and evening diner in Paris, to discuss in a non formal situation.
Date :
21st May (9 am – 5 pm), 22nd May (9 am – 12 am)
Location :
CNAM
61 rue du Landy
La Plaine St Denis, France (see https://goo.gl/maps/r8YgdFQqmh52)
Venue :
Take train RER B North (blue line) and stop at “La Plaine – Stade de France”. Caution, you have to buy a special Ticket (zone 1-2). Once there, it’s about 5 mn walk. Follow the map between the RER station and CNAM (see document attached).
Hotel :
Recommanded nearby Metro Stop “Gare du Nord” (8 mn), “Chatelet – Les Halles” (11 mn) or “Saint Michel Notre Dame” (13 mn).
Airport
Try to arrive at CDG Airport (north of Paris).
To go to Paris, 2 options :
“Paris by train” : 10€, 35mn. Buy a ticket at the airport. The connecting train CDG-Paris is the RER B, so it stops at “La Plaine Stade de France” which is useful is you fly back in the afternoon.
Taxi : 55€, 25mn (according to traffic)
Train :
Thalys and Eurostar arrive in Gare du Nord. Then it’s 8 mn with RER B to get to “La Plaine – Stade de France
