Labyrinth 3D is a program to render the light and shadow situation on the walls of a 3D labyrinth under a natural sunny sky, and then to walk and look around in the labyrinth. In places where no sunlight, skylight or reflections of them can reach, lamps can be put. The geometry of the labyrinth is purposely held simple to allow for fast computation. The labyrinth is generated randomly, based on a single number, the "level number". There is also a level editor where one can place blocks and stairs by hand.
