...mere $12,000 buys the system: a heat-sensitive chair that contours to the body and simulates zero gravity; a million-pixel, head-mounted display that feeds the eyes, headphones that fill the ears, and a quarter-inch hose that fits under the nose...
...forgive the graceless and oppressive flourescent lighting and the inexplicable psychedelic pixel boards--which flash subliminal and blatant fascist over-tones, convincing us of what a good time we're having--the renovated Memorial Hall basement is first-rate. The well-designed pine-stained study nooks ensure students a high degree of privacy, while the open areas--the Jetsonesque Coffee House and restaurants--are great places to mix and mingle with fellow students, hold informal meetings and grab a quick bite to eat. Loker Commons seems to be the type of ideal place that might serve as a social center...
...battlefield. But the information must be interpreted by human analysts hunched over fuzzy photos and computer screens. Identifying tanks and soldiers in pictures beamed back from a KH-11 Keyhole satellite is often a matter of counting dots on a computer monitor. "With 6-in. resolution you get a pixel for each shoulder and one for the head," says John Pike, space intelligence expert at the Federation of American Scientists. "That's hardly enough even to differentiate between military and civilian...
...form suitable for computer analysis. In this procedure, a video camera is used to feed an electronic representation of each black-and-white photo to a special circuit board that can be placed inside an IBM-compatible personal computer. The circuitry divides each picture into tiny dots called pixels, much like the process by which old Hollywood black-and- white movies are colorized. But instead of assigning colors to each pixel, the computer assigns each dot a number according to how light or dark it is. Thus on a scale of one to ten, a dark smudge or scratch might...
...most computer images, each dot, or pixel, on the screen must be mathematically specified. One frame of 35-mm film can require more than 6 million pixels; a 60-second sequence can cost $300,000 and take months to complete. To speed up the process, Catmull and Smith built a special-purpose machine -- the Pixar -- that divides the computational task among four parallel processors: three to control the red, blue or green washed onto each pixel; one to control the pixel's transparency...
