Path Tracing

Hi /porg/, Greetings from /3/.

Did you know that modern GPUs are now fast enough to do path tracing in real time?

Yep, it's essentially ray tracing in real time.  Soft shadows, ambient occlusion, indirect lighting, reflection, and refraction, all in real-time.  In fact, you can even do it in a web browser.

Have a nice day /porg/.

That's what they are doing.  The averaging just takes several frames before it smooths out.  I was thinking it might be better to reduce the frame rate a little, maybe by half, then you wouldn't see most of the graininess.

Shadow mapping != path tracing.  Path tracing gets you a lot more realism than just soft shadows and ambient occlusion.
