Valve's Impressive VR Demo Might Make You a Little Nauseous

It's no secret that the company behind Steam has big plans for virtual reality. Now we can get a look at what those ambitions will look like.

Valve's Impressive VR Demo Might Make You a Little Nauseous

When you first start watching David Finsterwalder's clips of Valve's VR demos, you might think you're looking at the real world. Then Portal 2 co-op robot P-Body shows up. Definitely not the real world.

But the basis of the environments in the demo does come from the earthly plane we exist on, captured by a process called photogrammetry. Games like The Vanishing of Ethan Carter have used photogrammetry to images of real-world objects into digital spaces. (Valve programmer Joe Ludwig has an in-depth explanation of the processes involved in these blog posts.) When stuff in VR starts looking this realistic, it's going to be hard to tell if you've taken a headset off or not.
