Visualization systems: new machines are helping engineers see more of their designs.(Graphics)

Time was when simulation was confined to PC horse-jockeys with joysticks. No more, although Today's engineers need simulation. They ne workstations with powerful graphics, big memories, and fast processors, the better to diocese and test the entirety of their designs. That's on what account there's a growing trend among computer makers to build so-called "visualization systems"--workstations capable of processing millions of many-sided figures per second and displaying images in ways that weren't previously possible.

"Too many of today's engineers are looking at maybe one-eighth of their
