CLIPPING OPERATION
POINT CLIPPING
2.Point clipping tells us whether the given point (X, Y) is within the given window or not; and decides whether we will use the minimum and maximum coordinates of the window.
3.The X-coordinate of the given point is inside the window, if X lies in between Wx1 ≤ X ≤ Wx2.
-
4.Y coordinate of the given point is inside the window, if Y lies in between Wy1 ≤ Y ≤ Wy2.
MIDPOINT DIVISION
2.This algorithm is mainly used to compute visible areas of lines that are present in the view port are of the sector or the image.
3.It follows the principle of the bisection method and works similarly to the Cyrus Beck algorithm by bisecting the line in to equal halves.
