Naïve raycaster, producing pseudo 3D output from 2D space

Naive Raycaster

This utilizes the very old method Wolfenstein 3D used - albeit modified. It sends out n rays from the camera, and the distance they intersect with an object at, you draw a rectangle of width , and height corresponding to the distance. This creates the illusion of a first person view. The actual calculation method for determining intersection distance is different from the Wolfenstein 3D method - but the end result is visually identical.

You can change the view in the running program by pressing 'v'.
