ABSTRACT = {We present a novel rendering system for defocus-blur and lens effects. It <br>supports physically-based rendering and outperforms previous approaches by <br>involving a novel GPU-based tracing method. Our solution achieves more <br>precision than competing real-time solutions and our results are mostly <br>indistinguishable from offline rendering. Our method is also more general and <br>can integrate advanced simulations, such as simple geometric lens models <br>enabling various lens aberration effects. These latter are crucial for realism, <br>but are often employed in artistic contexts too. We show that available <br>artistic lenses can be simulated by our method. In this spirit, our work <br>introduces an intuitive control over depth-of-field effects. The physical basis <br>is crucial as a starting point to enable new artistic renderings based on a <br>generalized focal surface to emphasize particular elements in the scene while <br>retaining a realistic look. Our real-time solution provides realistic, as well <br>as plausible expressive results.},
