DEMO DESCRIPTION The effects produced by the demo exceeded what were widely believed to be the limits of PC hardware in 1993 . Many techniques used by other demos, including Future Crew's own earlier work, were refined and reused in Second Reality. The demo had a soundtrack of Detroit Techno composed by Skaven and Purple Motion using ScreamTracker 3 . The degree of synchronization of the visuals with the music was highly impressive for its time. Introduction First the introduction plays, demonstrating text rendering on a background. After that is done several ships appear and fly away from the camera, demonstrating 3D rendering. After some distance the ships explode, sending out a shockwave (reminiscent of the " Praxis " explosion seen in the film " Star Trek VI "). The screen fades to display an Anthropomorphic creature, at which point Purple Motion 's main musical score for the demo begins. The image then flattens and falls horizontally to become a 3D, polygonal checkerboard. Bouncing sphere The music has now finished its introductory notes at this point and the legendary, first melody starts. Next a Glenz (additively blended) Polygon appears and bounces on the checkered surface, in perfect timing with the Orchestra Hits in the score, demonstrating 3D rendering and realtime mesh deformation. After a while another larger polygon appears and the smaller polygon begins bouncing inside the larger. Tunnel The next scene is hard to describe. It's a winding, fluid tunnel built up by discrete points that move towards the camera. This creates a feeling of rushing through the tunnel for the viewer. Oscillating circles The tunnel fades out into some oscillating circles which soon fade into the next scene. Moire patterns A scene that could be described as a light show. The scenes consist of multiple Moire patterns interacting. Moire patterns were quite popular in demos of that time. Creature Next an image of a creature rolls in from the right, and fades away. Some leaves and water are displayed, along with text characters floating downstream. The text says "Another way to scroll" and is an example of a Scroller , which was present in most demos of the time. Magnifying and rotating head After the text has floated by, again the scene changes to display something that resembles an evil looking human head with a . The sphere vanishes down in the lower right corner and the camera begins to spin right to reveal a repeating pattern of heads. The camera then falls down and bounces back up on the surface twice, after which the scene again fades out. Plasma Effect When the image fades in the camera is placed close to a surface changing texture every time. This is a continuation of their work in '' Unreal '' where they first introduced the 'unreal' plasma effect. Colored spinning cube After a few surfaces has been displayed a cube comes up that has these animated surfaces attached and spins around while translating towards and from the camera. Bouncing spheres After a while this scene fades and several small spheres begin falling down and bouncing on the ground surface in various fashions making patterns. Due to a bug in the code, the demo often hangs up at this part. Raytracing Again there is a fadeout and a fade in, this time we are looking at a scene with two spheres, and a sword starts translating towards the camera. The spheres will display a reflection of the sword as well as a reflection of the aforementioned reflection in the other sphere. The scene was rendered using Future Crew's homemade Raytracing software. Water As the scene changes again, this time image rendered will be of a surface changing shape, similar to that of water. Bouncing bitmap After this, an image will fall in from above, picturing a rider on what appears to be yet another fantasy creature. The image will hit the ground and bounce up while behaving like Jelly . 3D spacecraft fly-through In the next scene, a hovercraft flies around in a large 3D city, leaving it and heading up right over the text "Future Crew". This was later redone in the '' Final Reality '' demo by some of the previous members of Future Crew working for Remedy Entertainment . Future Crew bitmap The image fades out and the final scene fades in, an image of two Nut s with the text "Future Crew" written on them. Hidden part The demo can be started with a single character command line argument "2" through "5" to start from any of the later four parts. For another part that its introductory text calls "just an experiment" start the demo with a command line argument of "u". The screen will start filling with ever more stars warping towards the screen. RUNNING THE DEMO While the demo code remains freely available on numerous Internet sites, it is difficult or impossible to run Second Reality directly on a modern PC. The demo used its own Memory Manager which accessed the MMU directly in a way which is not compatible with modern Operating System s, accessed Video and Sound hardware directly (using its own built-in Device Driver s), and many of the timings in the demo do not scale up to modern CPU speeds. To run this demo on a modern machine running Windows or Linux , one can use DOSBox . DOSBox is even capable of emulating the exotic video modes and the Gravis Ultrasound preferred by Second Reality. The demo runs best on an Intel 80486 PC with a Gravis Ultrasound or a Sound Blaster Pro (or register-compatible clone). REMAKES The legendary state of this Demo inspired a lot of people to do their own Remixes of the show. The most popular ones are the following:
