Reg. evaluating Radiance results

Happy Monday everyone, Dr. Greg,

In a few days I will be evaluating my Radiance model with measurement
data (illuminance values). Can you please recommend some
guidelines/best-practices/research-papers that have conducted
such quantitative analysis, and came out with some methodologies for model
calibration, and their confidence intervals. My university had "Rendering
with Radiance", that could have been a good starter, but somehow it has
mysteriously gone missing. It has become a rare book, if I guess right. :slight_smile:

My experiment will be a controlled one, in which only the lights will be
turned On or Off and I will check their influence on results. The major
factor for anomalies could be from Sky, as initially I will be using Gensky
as the sky model.

I look forward for your suggestions. Thank you!

Best regards,
Vaib

Just for completion, I will be using rtrace/rsensor for illuminance
calculation..

Dear Vaib,

You should look at John Mardaljevic's Ph.D. thesis.

I hope that helps,

My stuff on the DMU site will be taken down sooner or later (in fact I'm surprised it's still there).

Hi Vaib,

Anyone looking for a copy of "Rendering with Radiance" should still contact "Randolph M. Fritz" <[email protected]>, who has been generously volunteering his time to distribute copies more or less at his cost.

If you use gensky or gendaylit for validation, be sure to input the global and diffuse values to calibrate them to your actual sky. In the end, John concluded in his thesis that accurate comparisons required a full sky (directional) measurement using a sky scanner (goniophotometer or gonioradiometer).

Best of luck!
-Greg
