lightpoints and 30 moving models per channel at 60Hz. Features include smooth shading, 3D perspective phototexture and anti-aliasing. MDC ELECTRONIC SYSTEMS McDonnell Douglas pioneered computer image generation for commercial flight simulators with its VITAL visual system. VITAL IV was introduced in 1977. The system is a Phase II night/dusk raster/calligraphic 1G generating 250 polygons and 6,700 lightpoints. VITAL VII was introduced in 1986 as a daylight, full-colour raster-only Phase III IG —with phototexture (up to 96 maps on line). A calligraphic lightpoint option has since been added. There can be up to eight channels per system with 1,000 polygons and 8,000 lightpoints per channel at 50Hz. VITAL Vile was introduced in 1990 as a lower-cost, day/dusk/night, raster/calligraphic Phase II IG with phototexture and 500,000- pixel standard resolution, a single cabinet housing three channels. Multiview is a cross-cockpit projected display using a mylar film mirror, with three to five channels giving a 135° to 225' field of view horizontally by 40° vertically. SOPS McDonnell Douglas Helicopters, with Pacific Optical, developed the head-tracked, two-channel Servo Optical Projection System. A 30° x 40° high-resolution (3arcmin/pixel) inset is blended into a 90° x 120° low- resolution (9arcmin/pixel) background and projected onto a dome. Hughes brings experience to bear on low-cost MicroPOLY II MEGATEK 944 Building on computer-graphic expertise, the modular 944 IG is able to generate 125,000-375,000 three-sided, smooth-shaded polygons/s at 30/60Hz with 1,024 x 1,024- pixel resolution. An optional special-effects processor provides anti-aliasing, lightpoints and fog/haze while an optional texture/pattern processor adds phototexture. Other options available include three to eight channels and sGemini Technology's Generic Visual System software. MERIT TECHNOLOGY Simtool Running at up to 30Hz on Silicon Graphics PowerVision computers using da tabases generated by Software Systems' Mul- tiGen, Simtool software provides texture, tr ansparency, unlimited moving objects, oc culting, terrain feedback, mission functions and environmental effects. MAGIK Software to manipulate DMA data includes MAGIK-Scene to generate outside- world images directly from elevation data. PARAGON GRAPHICS The Paragon family of low-cost image gen erators ranges from the $75,000 PG-.5 to the $495,000 PG-111 with phototexure. PG-.5 1,000 polygons, 2,000 lightpoints at 30Hz. PG.-I 1,000 polygons, 3,000 lightpoints at 30/60Hz with anti-aliasing, transparency and limited atmospheric and special-effects. PG-1.5 5,000 polygons, 20,000 lightpoints at 30/60Hz with optional smooth shading, mov ing models and database management. PG-II 10,000 polygons, 40,000 lightpoints at 30/60Hz with 256 moving models and optional distortion correction. PG-III As PG-II but with phototexture, which has been demonstrated.
