Every generation of videogames strives to be more realistic than the previous one. Therefore reaching photorealism is one of the future trends of videogame development. The steadily increasing performance of modern hardware paves the way for such a progress and is accompanied by the software innovations of gaming engines. Take for example the rain and water effects of the Unreal Engine 4.
A tech demo is one side of the coin. The other side is to put the potential of the gaming engines to use by creating videogames.
Get Even employs a 3D scanning technique to create a virtual and photorealistic replica of an existing environment. Their "What Is Real" teaser video impressively demonstrates the capabilities of their system. Unfortunately the release is planned not before the end of 2015.
Another great example for photorealism in videogames is The Vanishing of Ethan Carter. In contrast to the indoor footage of Get Even this games shows how to bring outdoor scenery to a new level. The authors use a technique called photogrammetry and explain in their blog how it works. Just take a look at the stunning 3D models that you can play around with in their blog post. Both the technique and its application in videogames look very promising. The game will be released on 25th September 2014 and can already be pre-ordered.
