WebMar 13, 2024 · Liang-Barsky Algorithm. The Liang-Barsky algorithm is a line clipping algorithm. This algorithm is more efficient than Cohen–Sutherland line clipping algorithm and can be extended to 3-Dimensional clipping. This algorithm is considered to be the faster parametric line-clipping algorithm. The following concepts are used in this clipping: WebJan 30, 2024 · Algorithm of Liang-Barsky Line Clipping: Step 1: Set the endpoints of the line (x1, y1) and (x2, y2). Step 2: Calculate the value of p1, p2,p3, p4 and q1, q2, q3,q4. Step 3: Now we calculate the value of t. t1 = 0 (For initial point) t2 = 1 (For final point) Step 4: Now, we have to calculate the value of pk and qk.
