At GDC 2019, Epic Showcased “Troll” and “Rebirth”, two stunning demos running on the RTX 2080Ti. Both use the Unreal Engine 4.22 and demonstrate Ray-Tracing in all its glory. “Troll” was developed by Goodbye Kansas Studios and Deep Forest Films.

Troll shows a woman, played by Alicia Vikander, interacting with fairies in the midst of a forest. It starts off light-hearted but hints at something dark towards the end. The teaser has been under development for a few months although there’s no set release date.

Epic also revealed “Rebirth” as a jaw-dropping example of photorealism. The demo was developed by Quixel, using only 3 artists and the original version of Unreal.

Rebirth shows a post-apocalyptic world with beautiful landscapes and stunning sceneries. Later, we see a hovering vehicle speeding towards an ultra-mordern structure jutting out from the mountains. The details in the video blur the line between real and virtual worlds.

Both the demos show great promise for Ray-Tracing and its applications. Currently, Unity, CryEngine and the Unreal Engine 4 employ ray-tracing technologies. In the future, we are expected to see quite a lot of games utilizing Ray-Tracing while offering better performance at the same time.
