Outline
The field of predictive rendering concerns itself with those methods of image synthesis which yield results that do
not only look real, but are also radiometrically correct renditions of nature, i.e. which are accurate predictions of
what a real scene would look like under given lighting conditions.
In order to guarantee the correctness of the results obtained by such techniques, all three different parts of such
a physically based rendering system have to be verified: the light reflection models, the light transport simulation
and the perceptually based calculations used at display time.
In this report, we will concentrate on the state of the art with repsect to the second step in this chain. Various
approaches for experimental verification of the implementation of a physically based rendering system have been
proposed until now. However, the problem of proving that the results are correct is not totally solved at present and
there is no standardized methodology available. We give an overview of existing literature, discuss the strengths
and weaknesses of the described methods and illustrate the unsolved problems.
