This is the bible for any serious animator. Although it was principally written for 2D animation, this book has crucial information for any animator (2D, CGI or model animation). It explains simply and clearly how to time a walk or a run; how to give your character a sense of weight; how force is transmitted; the effects of friction; spacing -and much more. The new foreword by John Lasseter puts these traditional skills in today's context, and gives praise where it is due. Every animator, would-be animator, animation studio and animation course should have this book.
