==Fonts== [[TrueType]] fonts use composite Béziers composed of '''quadratic''' Bézier curves (2nd order curves). To describe a typical [[type design]] as a [[computer font]] to any given accuracy, 3rd order Béziers require less data than 2nd order Béziers; and these in turn require less data than a series of straight lines. This is true even though any one straight line segment requires less data than any one segment of a parabola; and that parabolic segment in turn requires less data than any one segment of a 3rd order curve.
