Nettet13. mar. 2024 · The Liang-Barsky algorithm is a line clipping algorithm. This algorithm is more efficient than Cohen–Sutherland line clipping algorithm and can be extended … NettetAlgorithm 1. Read 2 endpoints of line as p1 (x1, y1) & p2 (x2, y2). 2. Read 2 corners (left-top & right-bottom) of the clipping window as (xwmin, ywmin, xwmax, ywmax). 3. Calculate values of parameters pi and qi for i = 1, 2, 3, 4 such that p1 = -dx, q1 = x1 – xwmin p2 = dx, q2 = xwmax – x1 p3 = -dy, q3 = y1 – ywmin p4 = dy, q4 = ywmax – y1

Nettet18. okt. 2024 · Algorithm: Step 1: Start Step 2: Given a line segment with endpoint P1 = (x1, y1) and P2 = (x2, y2). Step 3: Compute the 4-bit codes for each endpoint. If both codes are 0000, (bitwise OR of the codes yields 0000) line lies completely inside the window: pass the endpoints to the draw routine. NettetLiang – Barsky line clipping algorithm is faster line clipper algorithm based on analysis of the parametric equation of a line segment.
