"Doing the math, this 3-D revision of Moore's Law predicts that every five years computer graphics should improve in performance a thousandfold. My own experience over the last half-decade confirms this.... Alvy Ray Smith, one of the pioneers of computer graphics (now toiling away at Microsoft's research lab), told Howard Rheingold that 'reality is eighty million polygons a second.' To re-create scenes indistinguishable from reality, the computer needs to send that many of the tiny triangles to the screen. We're less than two years away from reaching that target, and there's no sign that things are slowing down."
