TRANSITION CONTROLLED E-BOOK ANIMATIONS

An e-book includes a rendering definition that specifies how content of the e-book is to be displayed to a user and how the user may interact with the displayed content. The rendering definition defines, for each portion of the e-book, the visual layout of content associated with the portion when the portion is displayed. The rendering definition also defines transition controlled animations for objects displayed in association with the content. The transition controlled animation of an object is an interpolation of the object over time and space that is manipulated by a continuous transition input. The transition input causes a transition from one portion of the e-book to another portion of the e-book. The transition controlled animation of the object is performed during transition from one portion of the e-book to the other portion.
