Abstract

Despite its popularity among researchers the radiosity method still suers of some disadvantages over other global illumination methods. Besides the fact that the original method allows only for solving the global illumination of environments consisting of purely diffuse surfaces, the method is rather computationally demanding. In the search for possible speed-up techniques one of the possibilities is to take also the characteristic features of the human visual system. Being aware of how the human visual perception works, one may compute the radiosity solution to lower accuracy in terms of physically based error metrics, but being sure that the physically correct solution won't bring any improvements in the image for the human observer. In the following report we briey summarize achievements in the radiosity research in the past years and present the state of the art in perceptual approaches used in computer graphics nowadays. We will give an overview of known tone-mapping an...
