This directory (https://github.com/NVIDIAGameWorks/GettingStartedWithRTXRayTracing) contains Chris Wyman's shader tutorials from the SIGGRAPH 2018 Course "Introduction to DirectX Raytracing." Please visit the course webpage (http://intro-to-dxr.cwyman.org) to get more details, more descriptive code walkthroughs, some prebuilt tutorial binaries, course presentations, and other information about the course.
Please read this document carefully before trying to build our tutorials. Given DirectX Raytracing is not fully finalized and stabilized, building code that relies on it is still somewhat complex and can fail in surprising ways. We have tried to specify all requirements and caveats, to avoid pain in getting started, and we will update this tutorial code as requirements change. Please contact us or log an issue (https://github.com/NVIDIAGameWorks/GettingStartedWithRTXRayTracing/issues) if you run into unexpected troubles not covered below.
Also note: None of the tutorial examples are intended to demonstrate best practices for highly optimized performance. These samples are optimized to provide an easy starting point, clarity, and general code readability (rather than performance).
