FONT DESIGNING USING CUBIC BÉZIER-BALL CURVES

The Bézier methods are basically and widely used in Computer Aided Geometric Design (CAGD) or CAD/CAM systems for free-form curves and surfaces modeling, such as vector-based drawing (Adobe Illustrator, Freehand , CorelDraw, etc.) as well as font design in PostScript, Microsoft Word etc. Farin (1996). Said (1990) has constructs new basis functions which are derived from basis functions of Bézier and Ball. This new basis function known as Cubic Bézier-Ball with shape parameters. Furthermore this method reduces to Bézier and Ball respectively by choosing suitable parameters. In this paper, we will be study the prospect of using cubic Bézier-Ball curves in designing fonts which satisfy the geometric condition G^0 and G^1 at their joint. We hope that this scheme could provide a greater flexibility to the font designer.
