Abstract: A character generator and its method are suitably applied to such a video title generator for adding title images to a video program. Specifically, the character generator according to the present invention analyzes the form of characters inputted by an operator through a keyboard, and generates a polygon model matching the inputted characters so that the inputted characters look a three-dimensional image. The generated polygon model is subjected to rendering processing and displayed on a computer display. The polygon model displayed on the display can be changed in real time by using three-dimensional parameter and so on, for a shadow or perspective, which is set by the operator on the GUI screen. Thereby, the three-dimensional character generated by transforming the inputted character into the three-dimensional form can be generated with simple constructions and operations and in real time.
