Linux Journal Issue #159/July 2007

You have to see the movie Shrek the Third in order to appreciate what DreamWorks has achieved with Linux on 3,000 CPUs doing 20 million CPU render hours. The hair movement, detail and lighting will knock your socks off and make them dance around the theater. We've got the lowdown on how it was all done; the various stages from storyboard to final cut.

As always, there's much more. Need Optical Character Recognition (OCR) that actually works? We'll tell you about a quirky command-line tool that does an outstanding job. Have you discovered the world of vector graphics? We'll get you working with Inkscape, even at the command line. And don't miss our interview with the Photoshop clone Pixel's creator Pavel Kanzelberger.
