			<content:encoded><![CDATA[<p>This is a bit old, but still cool: <a href="http://www.imdb.com/title/tt0327597/">the film <em>Coraline</em></a> (based on <a href="http://www.amazon.com/Coraline-Neil-Gaiman/dp/0380977788">a great book</a> by <a href="http://www.neilgaiman.com/">one of my favorite authors</a>) was stop-motion, not CG.  However, the facial animation was extremely smooth, due to a unique process.  The expressions were modeled by computer, exactly as they would have been for a CG animated feature.  Then for each frame, the faces were &#8220;printed&#8221; out on a &#8220;3D printer&#8221; (<a href="http://www.objet.com/">rapid prototyping machine</a>).  These tweened &#8220;frame faces&#8221; were swapped in for each stop-motion frame.  <a href="http://www.cgsociety.org/">CGSociety</a> has <a href="http://features.cgsociety.org/story_custom.php?story_id=4924">an article describing the production pipeline for this film</a>, an intriguing combination of CG and stop-motion animation.</p>
