title Discussing Photon-Mapping and Radiosity-Based Rendering Algorithms to Evaluate Qualitative Lighting Design in Contemporary Architecture
source Digital Design - Research and Practice [Proceedings of the 10th International Conference on Computer Aided Architectural Design Futures / ISBN 1-4020-1210-1] Tainan (Taiwan) 13–15 October 2003, pp. 351-360
summary This paper attempts to determine the impact of different light propagation algorithm on visual perception of qualitative lighting design in contemporary architecture. Radiositybased and photon-mapping-based light simulation software is used in this empirical study as a “switch” to isolate the occurrence of the specific lighting phenomenon. Images generated by the two rendering software are graded using a subjective lighting metric. The results show varying visual response. This finding informs architects that general radiosity-based renderer might not be adequate to portray accurate computational representation of translucency, directional diffused reflection and caustics; lighting phenomena observed in contemporary architecture.
