I just started working on lens flares; I need to see the sun’s location so I can test shadows! I am testing a new technique for dynamic lens flares based on the anatomy of the human eye, inspired by a paper by Tobias Ritschel.

The basic idea is to simulate the glare as a human eye would see it, instead of how a camera would see it. This means the glare has to be animated: the movements of the iris in response to bright light cause the diffraction streaks to change in subtle ways. Simulating an eye rather than a camera also results in a more grainy texture and a rainbow-colored lenticular halo, instead of the geometric internal reflections you normally see in camera flares.

Nice. It did kind of seem strange that all these games have lens flair to look like a camera instead of a real eye. It's kind of counter immersion.
