Fully dynamic path traced lighting on ~3B instanced triangles
(9/10) Unsolved problem in real-time path tracing
High-frequency specular reflections in ‘contemporary bathroom’ academic light transport scene (benedikt-bitterli.me/resources/)
(10/10) Unsolved problem in real-time path tracing
Sampling and denoising many-bounce specular chains
This is (up to) 100-bounce real-time path tracing vs high-spp reference.
(10+1/10) Original art credit for the Paris opera house model goes to GoldSmooth on TurboSquid. Our converted version has ~160M instanced triangles and is lit by ~500,000 emissive triangles and ~40 animated spotlights.
(10+2/10) This is real-time path tracing research.
Here's another previously-offline-rendering academic scene path traced in 13.6ms (74fps). Note that most of the light is coming through the diffuse transmissive curtains. benedikt-bitterli.me/resources/
(10+3/10) This is real-time path tracing research.
Another previously-offline-rendering academic scene path traced in 12.5ms (80fps). Note the mix of glossy, specular, and diffuse light transport.

(1/7) U of Utah recently published an alumnus interview with me. I am deeply grateful for my time in grad school at both U of Utah and UC Davis, and they asked if I had advice for current CS grad students (see thread). cs.utah.edu/docs/misc/COMP…
(2/7) Learn core computer science before specializing.
(3/7) Pursue high-risk, high-reward research. Ignore projects that lead to easy publications.
