Millimeter has an interesting article on a Mac application that Pixar created to allow its creative team to be more efficient when making changes to a film. “If you were in the Pixar screening room where director Brad Bird regularly reviewed images for The Incredibles, you would have seen a cool, new tool in action–the Review Sketch tool. This tool literally allowed Bird to draw on top of a projected image using a digitizing pen. The drawings were then accessible online by other members of his team… The Review Sketch tool, which resides on all the Macs at Pixar, contains features that addressed Bird’s style of working. The director could draw on an image, and then play it back with the image moving underneath his drawing. A slider let him choose the width of the anti-aliased line.”
