梁友栋-Barsky裁剪算法，Cyrus和Beck用参数化方法提出了比Cohen-Sutherland更有效的算法。后来梁友栋和Barsky独立地提出了更快的参数化线段裁剪算法，也称为Liany-Barsky（LB）算法。-You-Xin Liang Dong-Barsky clipping algorithm, Cyrus and Beck used parametric methods than Cohen-Sutherland algorithm more effective. LIANG You-Dong and Barsky was independently put forward a faster Parametric Line Clipping Algorithm, also known as Liany-Barsky (LB) algorithm.
