Radiance 2003 Workshop Image Contest

As part of the Radiance 2003 workshop, hosted by Greg Ward and Judy Lai at the Lawrence Berkeley National Laboratory in Berkeley, California, a photo contest was held among workshop participants.  The only requirements of the contest were that the photos be submitted by an attendee (though they could constitute the work of their peers), and that the images be generate somehow using Radiance.  The number of entries was small, but the quality was high, and we had difficulty picking our favorites.

First Place – Bristol University

Original Radiance Picture: TMsun.pic.

The copyright of these images belongs to the Graphics Group at University of Bristol. The temple was modeled by Veronica Sundstedt and Patrick Ledda.

Accurate light simulation is of highest importance in archaeological reconstructions when you want to investigate how a site might have looked like in the past. The ancient Egyptian temple of Kalabsha dates back to 30 BC but was moved in 1963 to a new site in order to save it from the rising waters of the Lake Nasser. Computer graphics in collaboration with Egyptologists makes it possible to recreate the temple, place it back to its original location and orientation, and illuminate it, as it may have appeared some 2000 years ago. This can be used as a useful tool for Egyptologists to test for changes in perception. Radiance lighting vizualisation and rendering system was used to ensure a high fidelity result.

The TMsun.pic shows a sun simulation of the temple of Kalabsha in January 30 BC, at its original location.

The TMpylon.pic shows a reconstruction of the Pylon of the temple and PylonReal.tif is a photograph taken at the same piece of the temple at the new site in January 2003.

Supplemental Images

The following images were also submitted by Bristol University, and show a simulated then vs. real now comparison.

Second Place - Christian Humann

Original Radiance Picture: pixar_1_1.pic.

This image is one of three that were commissioned by the architects of Bohlin, Cywinski and Jackson, Berkeley, for their design development presentation of a new building on the Pixar Animation Campus in Emeryville. The intent of the images were to help describe, to the Pixar clients, the interface of the architecture and daylight in fostering a creative and collabrative work environment.

Third Place – Buro Happold

Original Radiance Picture: blacktower001.pic.

This image was created as part of BH LiT’s natural lighting analysis and daylight glare analysis on the Tanaka Business School at the London Imperial College.  The image was generated by Andrew Bissell, copyright Buro Happold’s LiT.

The image was a portion of the glare analysis for the new louvre shading system on the existing engineering building’s south facade.  It shows the view an occupant of the space would have looking out through the louvre system on the summer solstice at 13:00 with a clear CIE sky.

The project consisted of a new building to house additional lecture theatres for the business school.  The architect devised a scheme that would achieve this by creating a cylindrical building that connects to a refurbished mechanical engineering building.  To control the daylight into the cylindrical building, it was enclosed within a gondola structure protected with a PTFE roof and glass walls, while a new louvre shading system was introduced to the existing engineering building

Honorable Mentions

Rob Guglielmetti – Renfro Design Group, Inc.

Original Radiance Picture: guglielmetti.pic.

This is a view of an atrium in a corporate headquarters building currently under construction.  This is a still from a series of "daylight animations" we performed, to observe how daylight travels around in the space after it is transmitted through the pedestrian bridge/facade (in lower left portion of rendering) and the clerestories at the top.
