Integrating Ray Tracing Into an Existing Engine: Three Things You Need to Know

In this video, Alex Dunn – Principal Devtech Engineer at NVIDIA, and Pawel Kozlowski – Developer Technology Engineer at NVIDIA, detail the three most important things developers need to know about integrating ray tracing into an existing engine.

Watch below:

3: Ray Tracing Will Transform Your Engine

Ray tracing introduces a couple of new concepts to the rendering pipeline. To support ray tracing effects like AO, diffuse GI, reflections, shadows, or caustics, you will have to manage acceleration structures for all necessary geometry, and in some instances, the link between them and materials – shader tables.

2: Old Rasterization Tricks Won’t Work with Ray Tracing

Skinning, out-of-screen lighting, tessellated terrain, particles, alpha-testing, transparency are a few examples. You will have to consider these variables in the production process, and build out time to mitigate resulting challenges.

1: You Must Factor a Performance Tax for Ray Tracing

Ray tracing can significantly improve visual fidelity of your games but it comes at a cost. Factor the impact on performance and memory in planning to improve frame rates.

You can see a live demo of RTX Ray Tracing on the show floor of GDC.
