Falcor is an open-source real-time rendering framework designed specifically for rapid prototyping.
Falcor accelerates discovery by providing a rich set of graphics features, typically available only in complex game engines, in a modular design that leaves the researcher in command.
Falcor is professionally designed and maintained by NVIDIA. It is open source and we welcome and encourage contributions from the community. We especially invite researchers to contribute implementations of published algorithms.

Foveated VR Rendering
This SIGGRAPH 2016 Emerging Technologies demo and SIGGRAPH Asia 2016 paper demonstrate gaze-tracked foveated rendering in VR that is imperceptible to the user and reduces shading computation up to 3x.
Hashed Alpha Testing
This I3D 2017 paper introduces a solution to alpha-tested geometry disappearing in the distance. This technique is now part of Falcor’s material system.
