Kim"I guess this is the place to ask: In various movies (most recently _The Abyss_) I have seen shots of the inside of submarines which include in the background the person steering the sub. Often, the person is staring at a screen which displays a wireframe image of the surroundings the sub is going through. Presumably, the wireframe is created from a processed sonar signal. My questions: Is this for real? Does it really exist? Where can I get more information on it? Or is it classified? What kind of computing power is required to analyze the sonar info? Thanks in advance. -- John H. Kim | (This space to be filled when I jokim@jarthur.Claremont.EDU | think of something very clever uunet!muddcs!jarthur!jokim | to use as a disclaimer)
