I developed a fast algorithm for raytracing bokeh

The way this works is by taking each sample and bidirectionally re-distributing its energy over the image plane. The result is smooth bokeh, even at low AA samples.

It is also able to do full lens simulation using a state-of-the art (polynomial optics) approach. Ever wanted to render through an 1900’s Petzval lens? Or the legendary Cooke Speed Panchro? Here ye go.

Can you give me more informations about your implementation ?
