Explain point clipping algorithm
Web1. Point Clipping: Assuming that the clip window is a rectangle in the standard position we have a point P = (x, y) for display, if the following conditions are satisfied : Xw min ≤ x ≤ Xw max , Yw min ≤ y ≤ Yw max. Where the edges of the clip window (Xw min , Xw max, Yw min, Yw max ) can be either the world co-ordinate window boundaries or viewport … WebLiang-Barsky Line Clipping Algorithm: Liang and Barsky have established an algorithm that uses floating-point arithmetic but finds the appropriate endpoints with at most four computations. This algorithm uses the …

WebThe Nicholl–Lee–Nicholl algorithm is a fast line-clipping algorithm that reduces the chances of clipping a single line segment multiple times, as may happen in the Cohen–Sutherland algorithm. The clipping window is divided into a number of different areas, depending on the position of the initial point of the line to be clipped. Fast ...
