1、Neural Shading for Real-Time GraphicsAndrew Allan,Devtech Engineer|Graphics Programming ConferenceIntroduction Why Neural Shading?Real-time rendering is about approximating reality with the highest fidelity possible within 16 or 33 milliseconds per frame.This pursuit has driven over 40 years of incr

2、easingly complex graphics pipelines and shader code.Cook,1984200020072019Insert images hereWhat is Neural Shading?Neural Shading integrates machine learning into the real-time rendering pipeline,replacing or augmenting traditional shading functions with learned neural networks.NeuralWhat is Neural S

4、lerators that remain idle during traditional rendering.Neural Shading allows us to harness these accelerators through Cooperative Vectors,integrating neural computation directly into the graphics pipeline.Classical vs.Neural Shading Real-time rendering has always relied on approximate mathematical s

5、olutions to simulate physically accurate effects.Classical engineering methods depend on these analytical models,but many shading problems are too complex or costly to express accurately.Neural Shading learns these complex relationships directly from data,bypassing the need for explicit analytical s
