One of those was non-photorealistic rendering,specifically pen-and-ink illustration. Our graphics group workedon two projects in this area. One was the <!WA1><!WA1><a href="http://www.cs.washington.edu/research/projects/grail2/www/projects/cg-illus/">automatic generation of pen-and-ink illustrations</a>given three-dimensional models and some texture information.

We wanted to be able tomagnify these images while maintaining sharp features. That is,instead of blurring the image to compensate for the magnification,we wanted features to stay crisp. This requires that a little moreinformation be stored with the image, but nothing that couldn't becaptured as the image was created. Anyway, we did a <!WA3><!WA3><a href="http://www.cs.washington.edu/research/projects/grail2/www/projects/res-ind-illus">project</a>addressing these problems, and the resulting paper was accepted by SIGGRAPH.For a quick preview, here's a brief demonstration of what we're trying to do.Note the sharp line segment in the righthand image.<p><center><table><tr>Various methods of image magnification</tr><tr align=center><td> <!WA4><!WA4><img src="http://www.cs.washington.edu/homes/salisbur/images/flatmag.gif"></a> </td><td> <!WA5><!WA5><img src="http://www.cs.washington.edu/homes/salisbur/images/blurmag.gif"></a> </td><td> <!WA6><!WA6><img src="http://www.cs.washington.edu/homes/salisbur/images/sharpmag.gif"></a> </td></tr><tr align=center><td>by pixel replication</td><td>by blurring</td><td>with a discontinuity</td></tr></table></center><hr><p>The rest of our graphics people are really good, and we're gettingmore people all the time.

My impression of Java is that it's kind of neat, butit has a ways to go to become really useful. It's still a real painto do lots of things. But with all of the hype and the money that'sgoing into it, it will succeed wildly.
