Introducing Ray Tracing in Unreal Engine 4

Ray tracing in Unreal Engine 4 is a powerful and flexible lighting system. It’s powerful because of its accuracy and quality. Never have you had the ability to do things like shadows and reflections like this in real time. It’s flexible because you can mix raster and ray tracing rendering features together as you see … Continued

Practical Tips for Optimizing Ray Tracing

To achieve high efficiency with ray tracing, you must build a pipeline that scales well at every stage. This starts from mesh instance selection and their data processing towards optimized tracing and shading of every hit that you encounter. Instance data generation In a common scene, there can be far more static than dynamic objects. … Continued

Introduction to NVIDIA RTX and DirectX Ray Tracing

“Ray tracing is the future, and it always will be!” has been the tongue-in-cheek phrase used by graphics developers for decades when asked whether real-time ray tracing will ever be feasible. Everyone seems to agree on the first part: ray tracing is the future. That’s because ray tracing is the only technology we know of … Continued

Q&A: Real-Time Ray Tracing in a Cinematic Scene

Six years ago, real-time ray tracing was seen as a pipe dream. Back then, cinematic-quality rendering required computer farms to slowly bake every frame overnight—a painstaking process.  By 2018, this level of performance was achievable in real-time, at 45 frames per second, enabling applications like video games to take a massive leap in graphical quality.  … Continued

Call for Papers: Real-Time Ray Tracing

Real-time ray tracing – the holy grail of graphics, considered unattainable for decades – is now possible for video games. Thanks to advances in GPU hardware and integration in standards like DirectX, game developers will eagerly add ray tracing to take the next step in visual quality and ease of content creation. To help game … Continued
