At GDC 2019, Epic Games showcased an amazing Unreal Engine 4 ray tracing tech demo, called “Troll”. According to the team, this demo was running on a single NVIDIA GeForce RTX2080Ti and showcased what developers can currently achieve with real-time ray tracing.
As Epic Games noted, the following tech demo will give you a glimpse of what developers and creators can do with ray tracing.
Running on Unreal Engine 4.22, the demo is said to mark an unprecedented level of cinematic-quality lighting, with complex soft shadows and reflections.
Nick Penwarden, director of engineering for Unreal Engine at Epic Games, said:
“Ray tracing is more than just reflections — it’s about all the subtle lighting interactions needed to create a natural, beautiful image. Ray tracing adds these subtle lighting effects throughout the scene, making everything look more real and natural and making it easier to create beautiful shots.”
