The session provides an introduction to Microsoft's DirectX Raytracing, including an overview of its new shaders, additions to the host API, and real world integration tips based on adding ray tracing into Remedy's Control. The first half focuses on ray tracing basics, an overview of the new shaders, and walking through a series of open-source shader tutorials. The second half highlights important changes to the DirectX API for developers integrating ray tracing into existing raster applications. We end by discussing important low-level details to help you achieve optimal ray tracing performance, including insights for optimal acceleration structures, instancing, reduced shader permutations.


The audience will learn about ray tracing in DirectX and some of the key challenges in integrating it in production renderers.
