Abstract

A character is represented in a character generator as a set of polygons. The character may be manipulated using three-dimensional animation techniques. A
code for a character may be used to access a set of curves defining the outline of the character. This set of curves is transformed into a set of polygons. The set of polygons may be rendered as a three-dimensional object. The set of polygons may be created by converting the curves into sets of connected line segments and then tessellating the polygon defined by the line segments.
Animation properties are represented using a normalized scale along a path or over time. Animation may be provided in a manner that is independent of the spatial and temporal resolution of the video to which it is applied. Such animation may be applied to characters defined by a set of polygons. Various three-dimensional spatial transformations, lighting effects and other colorizations may be provided. A
user interface for editing a character string may provide two alternate displays. A first display allows a user to input and view any desired portion of the character string for the purpose of editing. A
second display allows a user to view how the character string appears at a selected point in time during a titling effect for the purpose of animation. In both displays, the text is displayed in a three-dimensional form. This interface may be combined with a timeline editing interface for editing an associated video program, or other user interface, to permit layering of titling effects and adjustment of animation properties, positioning and timing.
