NVIDIA recently published Ray Tracing Gems, a deep-dive into best practices for real-time ray tracing. The book was made free-to-download, to help all developers embrace the bleeding edge of rendering technology. Ray Tracing Essentials is a seven-part video series hosted by the editor of Ray Tracing Gems, NVIDIA’s Eric Haines. The aim of this program is to make developers aware of various terms and concepts used in the field and with Vulkan, while also inspiring them with dramatic and beautiful uses of the technology. This post is about the fourth video in this series, the Ray Tracing Pipeline.
