Depth of field
My friend had added depth of field to the path tracer, which shows some nice results.

Without DoF:

With DoF:

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 tracer
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.

Off-line renderer - Be sure to watch in 720p!

Two of the subjects I'm following at the university at the moment are Additional Component Computer Graphics and Algorithms for Massive Data. 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...

This is a journal about how a young student decided to start implementing a path tracer.

I'm Arjan, a 23 year old CSE master student from the Netherlands. Having worked for Triumph Studios (the creators of the Overlord and Age of Wonders series) and starting a one man software development company (without many projects, I can tell ya http://public.ga...
