java maze is a java applet containing a 3D engine - code that simulates the display of a 3D world on a 2D surface such as a monitor. It uses a technique known as raycasting which was pioneered by id software in their groundbreaking 1992 FPS, Wolfenstein 3D. It is developed for the java platform, which theoretically allows an application to be created on a given computer system, and run on other computer systems that use different architectures or operating systems.
