Falcor is a real-time rendering framework supporting DirectX 12 and Vulkan.
Falcor addresses the need to accelerate development of graphics research and prototype projects by abstracting common rendering operations. It provides shader compilation, model loading, and scene rendering abstractions, along with a render graph system for building modular renderers. The framework includes raytracing support, an unbiased path tracer, post-processing effects, and integration with NVIDIA RTX SDKs including DLSS, RTXDI, and NRD. Python scripting support allows developers to drive rendering pipelines programmatically.
Falcor suits researchers and developers building real-time graphics applications on Windows or Linux who have access to raytracing-capable GPUs. The framework targets those who want to focus on rendering algorithms and techniques rather than low-level graphics API details. It requires Windows 10 with a DirectX Raytracing-capable GPU and NVIDIA driver support, or experimental Ubuntu 22.04 support on Linux. The project uses CMake for building and provides setup scripts for Visual Studio, Visual Studio Code, and Linux environments.
The project maintains active development with regular updates to its rendering capabilities and SDK integrations. The codebase shows consistent refinement of its abstraction layers and addition of new rendering techniques. Documentation covers both user-facing features and development workflows, indicating attention to developer experience. The framework continues to evolve its support across different platforms and graphics APIs while maintaining compatibility with current development tools and GPU driver requirements.
