WebDec 25, 2024 · Fast forward a few years, wave intrinsics are now available in newer shader models. Wave instrinsics are special shader instructions that allow us to retrieve data from the other threads in a wave, without the need for any synchronisation or expensive trips through memory. WebMar 25, 2024 · Wave intrinsics are allowed in raytracing shaders, with the intent that they are for tools (PIX) logging.
