<div>I'm still looking at this. My main hesitation is that the changes, while improving the accuracy for disk sources at close quarters, will increase the number of samples by a factor of six for distant disk sources. That's a trade-off I'd rather not make, so I'm thinking of how we might get around it.</div><div><br></div><div>Best,</div><div>-Greg</div><br class="Apple-interchange-newline"><blockquote type="cite"><p style="margin: 0.0px 0.0px 0.0px 37.0px; text-indent: -37.0px"><font face="Helvetica" size="3" color="#000000" style="font: 12.0px Helvetica; color: #000000"><b>From: </b></font><font face="Helvetica" size="3" style="font: 12.0px Helvetica">David Geisler-Moroder <<a href="mailto:David.Geisler-Moroder@uibk.ac.at">David.Geisler-Moroder@uibk.ac.at</a>></font></p> <p style="margin: 0.0px 0.0px 0.0px 34.0px; text-indent: -34.0px"><font face="Helvetica" size="3" color="#000000" style="font: 12.0px Helvetica; color: #000000"><b>Date: </b></font><font face="Helvetica" size="3" style="font: 12.0px Helvetica">November 27, 2008 2:31:01 AM MST</font></p> <p style="margin: 0.0px 0.0px 0.0px 21.0px; text-indent: -21.0px"><br></p> </blockquote><blockquote type="cite"> Hi,<br> <br> I talked to Greg at the workshop in Fribourg and handed the code over to him -- he wanted to have a look at it...<br> <br> Kind regards,<br> David<br> <br> <br> Erwin Zierler wrote: <blockquote cite="mid0003B2BB.492E7185@192.168.0.81" type="cite"> <pre wrap="">Hi,
I read the PDF file of your presentation yesterday and wondered if there are any plans to merge your code changes into the main Radiance distrubution at some point. Did you discuss this with Greg already? Seems to me it would improve the accuracy especially with circular light sources quite noticably.
We too did some work on Radiance together with Arne Duer in 2003/2004 so I was happy to see there is still interest in improving Radiance at the University of Innsbruck.

I did some validations of Radiance against these CIE test scenes, but
only for the
experimental test cases (chapter 4) and a few test cases with analytical
references
(chapter 5, TC 5.6, 5.7, 5.8). You can find the results in my
presentation from this
year's Radiance workshop. Unfortunately I did not use the test cases,
which are
dealing with daylight (I guess they would be more important for you).
Kind regards,
David

I am completing my PhD on daylighting simulation and I need any of CIE
performed validations of the Radiance in order to satisfy bureaucratic
procedures.
Has the Radiance been tested against CIE TC 3.33 test cases?
