Engineers from NVIDIA and Machine Games cover the technical aspects of adding ray traced reflections to Wolfenstein Youngblood. This is one of the first Vulkan based game engines to bring RTX technology to market. We'll perform a deep dive into the details of managing materials for hit shading in a forward renderer to denoising results, giving programmers and technical artists a solid understanding of what's involved.


The audience will learn how to implement and optimize specific ray traced reflection features for games using Vulkan API and extensions.

Intended Audience

Graphics programmers / developers who are interested in implementing Ray tracing reflection in general and in Vulkan extensions.
