Abstract
Abstract A system and method for creating three-dimensional or depth image font text characters using graphic three-dimensional object creation techniques and processors. The text characters can be represented as set descriptions of the characters. The text characters can also be represented as a three-dimensional geometric model including polygons constructed from vertices defined by three-dimensional coordinates. The representations are stored in a font storage and when a user specifies the text characters to be used in a depth image along with the font to be used for the text characters, the geometric representations of the characters are retrieved. If stored as a set, the set is converted into a geometric plot. Appropriate scaling and surface texturing operations are performed as designated by the user to create three-dimensional text character graphic objects. These text character graphic objects are transferred to a graphics processor to be manipulated as desired by the use and used to produce an image that can be further processed. <IMAGE> <IMAGE>
