For this project, I implemented the Disney BRDF using DirectX’s DXR library for enabling real time performance. To allow for quicker prototyping and development, I used Nvidia’s falcor rendering framework.

The implementation of the Disney BRDF itself was aided in large part by Joe Schutte’s blog post on the subject, which can be found in the references below.

The renders included on this webpage showcase a scene with a blend of direct and indirect light, as well as with exclusively indirect light (the softer images). Alongside this, the videos demonstrate the temporal antialiasing done with naive per-pixel accumulation between frames.
