This effect was achieved by picking a focal point on the focal plane for every pixel, and then jittering our camera rays to go through this focal point....


Path Tracing Adventures > Off-line rendering and block editor

Posted 21 April 2014

A lot of progress in this new entry! We have implemented the octree, which makes our renderer scale well with a large number of objects in our scenes. We have finished our block editor, which allows us to create, save and load worlds to render. And finally, we added some form of offline rendering.

The first pretty much lets you propose a graphics related project while the second focuses on processing large amounts of data or computations efficiently. So, of course, my proposal was to implement a path tracer w...
