Cohen-Sutherland 剪线算法：
它是一种线裁剪算法。其中二维空间(线所在的位置)被划分为9 个区域，然后有效地确定在感兴趣的中心区域中可见的线和线的部分。它可以快速检测并免除两种常见且微不足道的情况。它是由Danny Cohen和Ivan Sutherland 开发的。
Liang-Barsky 线裁剪算法：
它也是一种线裁剪算法。在该算法中，使用线的参数方程并求解四个不等式来找到线在视口中的参数范围。它是由You-Dong Liang和Brian A. Barsky 开发的。
下表详细指出了两种算法之间的区别。
| S.NO. | Factors | Cohen Sutherland Algorithm | Liang-Barsky Algorithm |
|---|---|---|---|
| 1. | Efficiency | It is less efficient. | It is more efficient. |
| 2. | Operations | In this Algorithm, each intersection requires both multiplication and a division. | In this Algorithm, each update of parameters requires only one division. |
| 3. | Approach | It follows the encoding approach. | It follows the parametric approach. |
| 4. | Calculation | It repeatedly calculates intersection along a line path even though the line may be completely outside the clip window. | In this, window intersections are calculated only once when final values have been computed. |
| 5. | Uses | It can be used only on a rectangular clip window. | It can be used for 1-D, 2-D, 3-D line clipping and sometimes 4-D line clipping too. |
