Regional Differences in the Perception of Daylit Scenes across Europe Using Virtual Reality. Part II: Effects of Facade and Daylight Pattern Geometry

Marilyne Andersen, Jan Wienold, Kynthia Chamilothori

While there is a growing use of complex facade designs in contemporary architecture worldwide and across Europe, little is known about the perceptual effects of these facades and the resulting daylight patterns on occupants, or about how such effects might ...

A new method to determine multi-angular reflectance factor from lightweight multispectral cameras with sky sensor in a target-less workflow applicable to UAV

Christoph Strecha, Manuel Simon Paul Cubero-Castan

A new physically based method to estimate hemispheric-directional reflectance factor (HDRF) from lightweight multispectral cameras that have a downwelling irradiance sensor is presented. It combines radiometry wilh photogrammetric computer vision to derive ...

An Experiment in Virtual Reality to Measure Daylight-Driven Interest in Rendered Architectural Scenes

Marilyne Andersen, Kynthia Chamilothori, Siobhan Francois Rockcastle

This paper introduces an experiment using a virtual reality headset to collect subjective evaluations of rendered daylit architectural scenes. By varying sky conditions and view directions from a fixed position in architectural renderings, the authors coll ...
