Watch an unbelievable augmented reality fight scene play out on a desk

The future isn’t only virtual — it’s also augmented.

Epic Games — the studio responsible for the Unreal Engine game-making tools — has released a video of how its technology can power incredible demonstrations of augmented-reality. The company published a fight scene that has three digital character duking it out in real time on a physical desk. This is mixing the actual world with video game characters, and these two realms are interacting with one another. Unreal is so aware of the surroundings that it is even capable of casting accurate, digital shadows onto a solid real-world surface. This isn’t available for you to mess around with yet, but the developer of the scene — Ádám Horváth — did show how he was viewing it through a Samsung S4 Mini smartphone to give you an idea of how this works.
