Key Features and Components

  • Fast ray tracing denoising solution
  • NRD is designed to work with 0.5 or 1 ray per pixel
  • Native implementation of the NRD API using engine capabilities
  • Includes three denoisers: ReLAX, ReBLUR, and SIGMA
  • Works with DX11, DX12, and Vulkan compatible engines on Windows 64bit
  • Currently supports the following signals:
  • Diffuse (with embedded ambient occlusion)
  • Specular or reflections (with embedded specular occlusion)
  • Shadows from an infinite light source (sun shadows)



Requirements
 

Operating System
  • Windows 10 version 2004, SDK v191041
  • Dependencies
  • NVIDIA Geforce GTX 1000 series or higher, AMD RX 6000 series or higher
  • Development Environment
  • Visual Studio 2017 or Visual Studio 2019
  • DirectX Shader Compiler: Latest Windows SDK version or latest GitHub version (for Vulkan shaders).



  • The NVIDIA Real-Time Denoisers is a fast solution that uses input signals and environmental conditions to deliver results comparable to ground truth images.



    Release Notes

    NRD V. 2.9:
    • DLSS integrated into the sample with dynamic resolution scale support
    • Introduced new denoisers for ambient and specular occlusion
    • Introduced stand-alone ReLAX diffuse-only and specular-only denoisers
    • Added new functionality - advanced pre-accumulation filtering pass
    • Added new functionality - user-driven antilag (user provided history confidence)
    • Added helpers for better many RPP support
    • Added optional material ID aware spatial filtering support
    • Improved white-box integration support (UE4, consoles, custom engines)
    • Meters to units conversion now happens inside the library
    • ReBLUR and ReLAX: IQ improvements
    • ReBLUR and ReLAX: now compute local curvature to improve specular tracking
