Project introduction

NRD

full name Nvidia Real-time Denoiser , It is a spatiotemporal dual domain noise reduction library being developed by NVIDIA , Designed to deal with low RPP（ray per pixel） The signal .

The graphics of this technology API The environment is ：DirectX11、DirectX12 as well as Vulkun. There are three integration methods , One way is to use Nvidia Of NRI（NVIDIA Rendering Interface） Package the above three API, To integrate .

Project objectives

stay Falcor Integration under the framework nrd.

Division of labor

Shared responsibility with team members NRDPass.h And NRDPass.cpp Compiling

The author is responsible for Private sector Statement and definition of . And record in subsequent articles .

Work at current stage

Modelled on the Falcor other RenderPasses To write NRDPass.h

Which includes NRDPass Class design .

contain Falcor The required interface 、NRD Corresponding API.

Don't show too many details .
