Two papers conditionally accepted to SIGGRAPH Asia 2017

We will be presenting two exciting papers at SIGGRAPH Asia 2017 in Bangkok. If you don’t want to wait until November, please find preprints on arXiv:

Scratch Iridescence: Wave-Optical Rendering of Diffractive Surface Structure

Sebastian Werner, Zdravko Velinov, Wenzel Jakob, Matthias B. Hullin
https://arxiv.org/abs/1705.06086, 2017.

Many real-world surfaces are covered in fine scratches that diffract light in colorful ways. Our model seamlessly transitions between ray optics and wave optics to recreate this intricate effect.

Snapshot Difference Imaging using Time-of-Flight Sensors

Clara Callenberg, Felix Heide, Gordon Wetzstein, Matthias Hullin
https://arxiv.org/abs/1705.07108, 2017.

Computation of image differences is a key operation in computational imaging. We use time-of-flight sensors to perform this operation in a single shot, and discover some remarkable features.
