Ray Casting is the graphic technique of using 2D data to display what would look like a 3D environment. This technique has been used in games such as Wolfenstein 3D, and even more advanced in the Doom series.

What HappensEdit

Rays are drawn from the point the player would be in to the environment to the front. Wherever each ray hits, that distance is recorded into the appropriate column of pixels. When all of the pixels are allotted, the screen will appear to look 3D.
