If I'm submitting a link, do I still get to add text here? I have to admit this is my first time submitting, and it's my own content. I love finding interesting nerdy things and software/hardware deep-dives on HN.

A year ago I found Fabien Sanglard's post about Andrew Kensler's postcard pathtracer, and I was hooked. So I spent some weeks digging through the code further, and then set out to write about my findings.

Well, completing the series has taken me over a year. But I consider these four posts done now! So I just hope people will also find something of value within them.

PS: I also have a CUDA implementation going, but I only included a short video as a bonus at the end of post 3. I should get back on that. :)
