NPR shading evaluation on virtual reality

Abstract

[en] Today, technology is evolving faster than ever. We are surrounded by in an endless number of new devices that try to recreate reality, and it is increasing, day by day, a more authentic immersion in game worlds. Virtual reality has recently experimented a boom and it does not look like this increasing trend is stopping any soon. It already has many different devices capable of using this technology and millions of consumers of this new reality all around the world. As you can imagine, the content visualized through the augmented reality glasses is not the same as the content that has been used for conventional computer games. This work proposes a set of metrics to objectively detect the quality of virtual reality images. To do this, a set of lighting techniques are implemented and afterwards analysed. Using these lighting techniques and generating a set of test images, we have been able to identify which visualization techniques are the most useful and well suited to be used in virtual reality.
