# A Hierarchical Automatic Stopping Condition for Monte Carlo Global Illumination

@inproceedings{Dammertz2010AHA, title={A Hierarchical Automatic Stopping Condition for Monte Carlo Global Illumination}, author={Holger Dammertz and Johannes Hanika and Alexander Keller and Hendrik P. A. Lensch}, year={2010} }

We introduce a hierarchical image-space method to robustly terminate computations in Monte Carlo image synthesis, independent of image resolution. The technique consists of a robust convergence measure on blocks which are either recursively subdivided or terminated independently, using a criterion which separates signal and noise based on integral estimates from two separate sample sets. The technique can be easily implemented, as the evaluation of the error measure only requires a second…
