On this map, the "player" is represented as a blue triangle, the start as a red triangle, the smiley face as a green triangle, the rocks as rotating white triangles, the OpenGL logos as stationary white triangles, and the rat as an orange triangle.Ĭornell University's Maze in a Box, a project to create 3D graphics using the Atmel Mega32 microcontroller, used the 3D Maze screensaver as inspiration. Users can also enable an overlaid map, which constantly displays the maze using simple vector graphics. If the maze is completed and reset while upside down, the next maze may be traversed as if it were upside down, hugging the left wall instead of the right. Upon reaching it, the maze will reset and another will be generated. The exit to the maze is a floating, translucent smiley face. When this happens, the "player" will traverse the maze following the left wall rather than the right until the exit is found or another gray rock is encountered, flipping the camera right-side up again. Additionally, the "player" will encounter rotating polyhedric gray rocks that, when touched, will flip the camera upside down and turn the floor into the ceiling. Users can customize these textures, swapping them out for animated psychedelic patterns in later versions, or may instead create their own custom textures.Īs the maze is traversed, several objects can be found inside it, including floating "OpenGL" logos, images of globes on the walls (which is seen on the cover of the OpenGL Programming Guide), and a 2D sprite image of a rat that is also moving through the maze. From there, the maze is automatically traversed using the right-hand rule, which will guarantee the maze will eventually be solved because all of the randomly-generated mazes are simply connected (there are no looping paths).īy default, the maze is textured with brick walls, a wooden floor, and an asbestos tile ceiling. The maze is randomly generated each time, with the "player" navigating through it in first-person, spawning in front of a floating start button. ![]() ![]() com/ IdaSurface.Screenshot of the 3D Maze Screensaver displaying the Windows 95 start button.ģD Maze is the name given to a screensaver, created in OpenGL, that was present in Microsoft Windows from Windows 95 until it was discontinued after Windows ME.
