Practical Techniques for Ray Tracing in Games (Presented by Imagination Technologies)

Gareth Morgan  |  Leading Software Design Engineer, Imagination Technologies
Jesper Mortensen  |  Graphics Engineer, Unity


Location: Room 301, South Hall

Format: Sponsored Session
Track: Programming
Vault Recording: Video


Ray tracing has, for many years, been the gold standard of visual realism in 3D rendering. Thanks to advances in modern graphics hardware, ray tracing is now a feasible technique for use in games. This presentation will describe how ray tracing has been successfully integrated into the Unity engine and combined with traditional rasterized 3D graphics.Accurate shadow rendering is a key component of visual realism. Ray traced shadows can provide good performance, accurate penumbra, and they avoid some of the artifacts and pitfalls of shadow maps and shadow volumes.Reflections are an obvious application for ray tracing in games. Reflections and refractions off irregularly shaped objects can add an element of realism that is difficult to achieve any other way.This session will cover the technical details of how these effects are blended into the Unity engine's rendering pipeline without sacrificing real time frame rate.

Takeaway

Attendees will gain an understanding of how ray tracing can be used to enhance their current-generation game engines in a meaningful way. They will also develop an understanding of which effects are possible for which levels of ray tracing performance.
