This paper presents an analysis of the irradiance estimator often used in photon mapping algorithms and concludes that the classical approach with a constant kernel overestimates the correct value. We propose a new estimator that solves this problem and provide both theoretical and empirical studies to verify it This work has been supported by the research projects coded TIN2007-68066-C04-01 and TIN2010-21089-C03-01 (Spanish Commission for Science and Technology), by grants VALTEC09-2-0118 and 2009SGR643 (Catalan Government) and by FEDER funding from the European Union |
