Reconstruction of Arabic calligraphy by using Wang-Ball curves / Noorehan Awang ... [et al.]
Published 2021“…Rational Wang-ball which is derived from non-rational Wang-ball curves, where it has been proven that a rational Wang-ball curve is a rational Bezier curve of the same degree and vice versa. A recursive algorithm for plotting rational Bezier and Wang-ball is obtained by the de Casteljau and Wang algorithm using homogeneous coordinates and an efficient algorithm for evaluating a rational Wang-ball curve is attained and has a linear time complexity (Dejdumrong et al., 2001). …”
