After Effects Expressions - Marcus Geduld

Put the power of Expressions to work in your animations with controls and efficiencies impossible to achieve with traditional keyframing techniques.
No programming skills are required. Foundation concepts and skills orient the new designer and serve as a handy reference to the experienced one. Basics of creating Expressions, variables, commands, and Expression helpers precede the leap into JavaScript and math essentials for more advanced Expressions that include randomness and physical simulations.
Full color illustrations display the scripts and the resulting effects, Pick Whip techniques, and sequential animations. Downloadable companion files include QuickTime movies of the demo animations, AE project files and more at http://www.taylorandfrancis.com/cw/geduld-9780240809366/
