Abstract

We present our approach for incorporating realistic lens flare rendering in a production renderer based on a previously presented physically based lens simulation technique [Hullin et al. 2012]. We describe the approximations and sampling techniques behind efficient lens flare rendering, in addition to introducing flexible artist controls and workflows for this purpose. Using "The Lego Movie 2: The Second Part" as a case study, we show that these approaches are efficient and work well in a production environment.
