This paper describes the development and validation of a new service allowing products, such as tiles, to be viewed on a computer authentically in the actual lighting conditions of the area in which they are to be installed. This service leverages recent developments in physically based global illumination and High Dynamic Range (HDR) imaging, enabling real-world lighting to be accurately captured, transferred to a computer and used to relight any choice of tile in a highly realistic manner.This project is funded by TSB ICT for Manufacturing and Construction project 14345-87267. The project is also partially supported by ICT COST Action IC1005. L. P. Santos is partially funded through the FCT (Portuguese Foundation for Science and Technology) within project PEst-OE/EEI/UI0752/2011
