The next progress meeting of BiRD will be held at CNAM, in La Plaine St Denis (FR), 21 May (9 am – 5 pm) to 22 May (9 am – 12 am). Please, save the date in your agenda and register.
Registration – please register here online
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.
May 21 (9 am – 5 pm), May 22 (9 am – 12 am)
61 rue du Landy
La Plaine St Denis, France (see https://goo.gl/maps/r8YgdFQqmh52)
How to get to CNAM
Map Metro Paris
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).
Recommanded nearby Metro Stop “Gare du Nord” (8 mn), “Chatelet – Les Halles” (11 mn) or “Saint Michel Notre Dame” (13 mn).
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)
Thalys and Eurostar arrive in Gare du Nord. Then it’s 8 mn with RER B to get to “La Plaine – Stade de France
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.

Rhopoint Instruments is a UK based designer and manufacturer of test equipment primarily focussed towards appearance quality.
The company was founded in 1988 as a manufacturer of glossmeters. Since this time, the product range has developed and grown to test not just gloss but many other parameters of total surface quality including Orange Peel / DOI, Haze, Texture, Defect Analysis, Shade and Opacity.
Their handheld instruments are designed to be used in both research and development and production environments in numerous industries including: paints and coatings, automotive, yacht manufacture, metal polishing, polished stone, smart phone, tablet PC and laptop covers, coil coating, printing and graphic arts, powder coating, furniture and plastics.
Rhopoint Instruments is part of the Rhopoint group of companies which operate to ISO9001:2008 Quality Management Systems.
First day will be a workshop on gloss, with the aim to provide you the last progresses in the field of gloss perception, gloss comprehension and gloss measurement.
The second day will be devoted to BiRD project progresses (Sparkle, BRDF and data files).
Workshop “Open questions on gloss measurement”
October 23rd 2018, Madrid, Spain
This workshop will be the opportunity to talk about research questions on gloss as a visual attribute and about issues and new developments with respect to gloss measurement.
The workshop will be followed by the kick-off meeting of a new Joint Technical Committee (JTC) on Gloss which has been proposed to CIE and is pending to be officially approved.
We would like to invite you to contribute to the workshop, by proposing a talk on the topic of gloss. It must be research oriented and non-commercial. If you are interested, please send a short abstract of 200-300 words to Ana Rabal (firstname.lastname@example.org) before October 16th 2018. This abstract will be reviewed by the scientific committee composed of Frédéric Leloup (KU Leuven and propose co-chairperson of the CIE JTC on gloss), Gaël Obein (CNAM and propose co-chairperson of the CIE JTC on gloss), Esther Perales (Universirty of Alicante) and Alejandro Ferrero (CSIC). The final program will be published on October 17th on the website along with selected abstracts.
4th Project progress meeting of JRP BiRD
October 24th-25th 2018, Madrid, Spain
The meeting will be focused in the progress of the project. The work done within every work package as well as the schedule of deliverables will be reviewed. A questions and answers session on the development and trends of the project will be held, so stakeholders and collaborators will be able to pose issues.

JTC 12 (D1/D2/D8): The measurement of Sparkle and Graininess
Div2 of CIE has validated the creation of aJoint technical committee (JTC) on sparkle, chaired by Alejandro Ferrero (CSIC, ES), and co-chaired by Youngshin Kwak (Head of CIE Div1, KR).
The term of reference of the JTC is “To provide a methodology to measure sparkle and graininess, and to develop a measurement scale. Measurands will be defined and the requirements for their measurements will be well normalized, in such a way that different instruments can provide the same spectrophotometric data from the same specimen. A psychophysical method will be recommended to obtain visual data, and its correlation with the spectrophotometric data will be worked out to develop the measurement scale for sparkle and graininess.”
If you want to joint JTC Sparkle, you are welcome.
Chair: Alejandro Ferrero (ES)
Recommendation on the geometrical parameters for the measurement of the bidirectional reflectance distribution function (BRDF)
Next meeting of TC2-85
Next meeting will be held in Eindohoven (NL) around June 12, 2018 during the Div2 annual meeting. A special emphasis will be given to polarization effect in BRDF measurements during this meeting. If you want to joint TC2-85, you are welcome. We need your support and knowledge are user of BRDF measurements, as multi-angle spectrophotometer or goniospectrophotometer manufacturer, as standard artefacts manufacturers.
