Fast Daylight Simulation and Analysis

This paper presents a fast algorithm for daylight simulation and analysis of complex architectural environments that considers both direct sunlight and diffuse daylight. Shadow determination is performed using a combination of parallel projection and ray tracing techniques. Parallel projection provides execution times that are linear with respect to the number of polygonal objects in the enviro...

Camera Calibration for Daylight Specular-Point Locus

In this paper we present a new camera calibration method aimed at finding a straight-line locus, in a special colour feature space, that is traversed by daylights and as well also approximately followed by specular points. The aim of the calibration is to enable recovering the colour of the illuminant in a scene, using the calibrated camera. First we prove theoretically that any candidate specu...
