smallpt: Global Illumination in 99 lines of C++

Finally releasing a little project I’ve been working on. A small project, although I spent an insane amount of time tweaking it. My hope is that it can serve as a concise reference to anyone wondering what’s involved in a basic global illumination renderer. Honestly, since I don’t explain the concepts or the shortcuts used, and the code is ugly in some places, I don’t know how valuable it will be to a someone just entering the field. A basic renderer can be kicked out in less than a day, perhaps a concrete working example like this can fill in any missing details for someone just starting off.

    Cool. :-)

    Pane inspired me to make a ray tracer for my undergrad graphics course. I didn’t add global illumination, but I did make a short animation ( Now I need to look at lighting and material for my grad study and I think this piece of code is a very good crash course for global illumination.
