I was taking a look at your frame-by-frame of the teaser trailer, and I figure you folks probably know what the &#8220;scan&#8221; scene on <a href=\"http:\/\/www.theonering.net\/movie\/preview\/page04.html\">http:\/\/www.theonering.net\/movie\/preview\/page04.html<\/a> really was, but I wanted to make sure. <\/p>\n<p>I believe it&#8217;s showing a technique called &#8220;laser stripe scanning&#8221;, which is a method of building a 3D computer model used in computer animation. The idea is to have an artist first construct a sculpture of some model such as a character&#8217;s head. The model is then placed in a laser scanner, a device that shoots a thin laser stripe at the sculpture, and records its reflection with a special camera. It can then compute, based on how the stripe&#8217;s image follows the bulges and dips on the sculpture, what the 3D shape is. After some further analysis is done on this 3D data, it can be used in animation. <\/p>\n<p>The technology involved here is relatively new, and has been viable for use in the animation industry only for the past couple of years, but it&#8217;s a very effective method of creating realistic 3D computer models. At <a href=\"http:\/\/graphics.stanford.edu\/projects\/mich\/\">http:\/\/graphics.stanford.edu\/projects\/mich\/<\/a> you can see some interesting photos and information on a project using laser stripe scanning to digitize the sculpture work of Michaelangelo in Italy. The people doing this for LOTR are probably using similar (albeit smaller) equipment. <\/p>\n<p>I&#8217;m a graduate student in computer science at the University of Washington in Seattle. My adviser here, Dr. *******, did some of the pioneering work on this technology as his Ph.D. thesis back in the mid 90&#8217;s. <\/p>\n<p>Regards,<br \/>DA<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This is an email I received from super Ringer fan DA: Hello, Thanks for a great site!
