Presentations from the workshop in Espoo are available in the Stakeholder Area.

The Joint Research Project “New quantities for the measurement of appearance“ will provide new traceable primary references in spectrophotometry. For more  information, please visit the project website https://bxdiff.cmi.cz/. The project will involve defining the new quantities Bidirectional Transmittance Distribution Function (BTDF) and Bidirectional Surface Scattering Reflectance Distribution Function (BSSRDF), and further improving the measurements of Bidirectional Reflectance Distribution Function (BRDF).

The news story about EMPIR project 16NRM08 is  published on the EURAMET website.

The 5th CIE Expert Symposium on Colour and Visual Appearance will take place in Hong Kong on 20-24 April 2020.

• Abstract Submission is open and closes 23th October 2019.
• Early Registration opens 11th October 2019.
• For interested parties there are sponsorship opportunities available.

The symposium provided the attendees the opportunity to present the state of the art in our understanding of the perception of the visual attributes, such as colour, texture, translucency and gloss.

Detailed information is available on CIE webpages .

Following new papers have been published recently within the EMPIR 16NRM08 Project “Bidirectional reflectance definitions” (BiRD):

A. Ferrero, Theoretical evaluation of the impact of finite intervals in the measurement of the bidirectional reflectance distribution function, J. Coat. Technol. Res (July 2019)

F. B. Leloup, J. Audenaert, P. Hanselaer, Development of an image-based gloss measurement instrument, J. Coat. Technol. Res (April 2019)

The presentations and minutes have been uploaded on the project website, in the stakeholder area.

Our workshop on Visual Appearance took place 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)

How to get to CNAM

Map Metro Paris

Agenda

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

We have an new industrial who joined the group of BiRD’s stakeholders.
