Massively Parallel Path Space Filtering in Game Development

Originally published at: Massively Parallel Path Space Filtering in Game Development | NVIDIA Developer Blog

At SIGGRAPH 2019, NVIDIA explained how to harness massively parallel path space filtering in order to achieve high quality real-time ray traced global illumination in games.  Imagine seeing a point on the ceiling through a mirror. With offline rendering, you could collect the radiance over a hemisphere to determine how bright it is there. This…
