Radiance Workshop Presentations, 2021 & 2022
In connection with Loisos + Ubbelohde I have twice presented at the annual International Radiance Workshop. These talks described recent work and research on daylighting and simulation, which I played a key role in.
"Building and Validating a BSDF of a Looped Metal Mesh" given with Alan DeMarche, 8/4/22 at the 20th International Radiance Workshop, Toronto, Canada [link to slide deck and audio on the Radiance website]
This presentation was given in collaboration with Alan DeMarche at Loisos + Ubbelohde, and covered the long and complex process which I, Alan, and our colleagues went through to develop a highly accurate simulation model of a fencing material that is being used as a shading material in a very large building in the Middle East. To effectively simulate this material, we had to generate a Bidirectional Scattering and Distribution Function (BSDF), which we then validated in a number of ways against samples of the actual material.
"What to Do When the Sky is Blue" given 8/19/21 at the 19th International Radiance Workshop, Bilbao, Spain

"What to Do When the Sky is Blue" covered practical considerations of working with colored sky models (such as the Utah Sky) when doing daylight simulation in architecture using the physically-based rendering software Radiance. Topics covered included: choosing when to use a colored sky model; considerations for other aspects of simulation, scene, and modeling; and post processing practices for use with colored sky models such as white balancing, use of the pcond command with color primaries, and more. The presentation was illustrated with demonstration examples and practical results taken from work done by Loisos + Ubbelohde.
