Deadline: August 31, 2002

Purpose of Workshop:
To provide researchers with an opportunity to present their work with Radiance, and to share ideas and solutions with workshop participants.
Speakers shall give a 20 minute talk, which will be followed by 10-15 minutes of open discussion. No printed proceedings will be produced, but a CD-ROM will be distributed to attendees that will include electronic materials submitted by the speakers and edited by the organizers.

We have received 29 pre-registrations for the workshop, and a list of planned speakers and preliminary titles is broken into categories below:



  Greg Ward, "Radiance 3.4 and Open Source Development"

Daylighting Studies
  Giulio Antonutto, "a radiance application in daylighting analysis" (from his thesis)
  Annalisa Simonella, "daylighting analysis" (two titles offered -- we liked them both)

Lighting Analysis
  Jack de Valpine, "Architectural Visualization: Radiance in Production"
  Georg Mischler, "Simulating daylight redirection systems"
  Haico Schepers, "Radiance use in Australiasia: an Engineers experience"

Applications in a Teaching Context
  Raphael Compagnon, "IRAD: a simple automated simulation program to study daylighting in rectangular room without knowing much about RADIANCE"
  Axel Jacobs, "Using RADIANCE for teaching lighting simulations on a European Masters course"

Extensions, User-interface, and CAD Links
  Jean Brange, "a C4D/Radiance converter which is usable on MacOSX"
  Roland Schregle, "The RADIANCE Photon Map"
  Greg Ward, "The Holodeck Interactive Ray Cache"
  Jan Wienold, "Radiance developments at Fraunhofer ISE"

Special Materials (BRDF BTDF, etc.)
  Peter Apian-Bennewitz, on material modeling

High Dynamic Range Images
  Mehlika N. Inanici, "Post Processing of Radiance Images: Virtual Lighting Laboratory"
  Patrick Ledda, "Perception of High Dynamic Range Scenes"
  Bernhard Spanlang, "Creating Lightmaps from HDR using Radiance"
  Greg Ward, "The Photophile Browser for HDR Images"

Special Applications
  Alan Chalmers, "Very Realistic Graphics for Archaeological Site Reconstructions"
  Raphael Compagnon, "PPF: a tool to study solar irradiation and illuminance in urban area"

The names and titles above are not final, and we may get new speakers and lose some people before we can provide a proper workshop agenda in September. About half the pre-registrants have said they would like to come but do not wish to speak, and we can accommodate everyone we have heard from at this point.

By August 31, we will also need the final titles and abstracts for all the talks, along with any materials the speakers wish to include on the workshop CD-ROM. At minimum, we would like to get a copy of each speaker's presentation in PowerPoint, PDF, or HTML (preferred) format, and a short bio with contact information. If the speaker also has test scenes, images, and/or software they would like to share, these would be most welcome. We need to get all of these materials in order to have sufficient time to assemble them into a usable CD-ROM, so we cannot promise to include anything submitted after the August 31 deadline.

Thank you to everyone who responded, and we look forward to meeting you at the workshop!
