Error control is important in a large number of applications of radiative transfer simulation. It allows to ensure a given degree of precision in the computed solution, and also makes it possible to gradually trade computation time for quality in the resulting images. In lighting simulations using hierarchical radiosity methods, the evaluation of visibility relationships constitutes the major part of the total computational effort, making it the ideal target of various approximations that finally influence the image quality. In this work we first study the impact of visibility approximations in the computation of form factors, on the accuracy in the simulation results. Such an approach can be used in coordination with an error control algor...
