## What it is
Falcor is NVIDIA's open-source real-time rendering framework for rapid prototyping of graphics research, built on DirectX 12 and Vulkan. It provides abstractions for shader compilation, model loading, scene rendering, raytracing, a modular render graph system, and integrations with RTX SDKs like DLSS, RTXDI, and NRD.

## Use cases
- prototype real-time rendering algorithms
- build a path tracer for graphics research
- experiment with DirectX ray tracing and DXR
- create modular renderers with a render graph
- test denoising techniques for low-sample path tracing
- implement SIGGRAPH rendering papers quickly
- arrange scenes and author camera animation paths

## When to choose
- you are doing graphics research or prototyping rendering techniques
- you need raytracing and RTX SDK integrations without engine overhead
- you want a modular framework instead of a full game engine
- you work on Windows with an RTX-capable NVIDIA GPU

## When to avoid
- you need to ship a cross-platform game or application
- your target platform is Linux or macOS
- you lack a DirectX Raytracing-capable GPU
- you need a production game engine with editor and asset pipeline for teams

## Facets
- artifact type: framework
