It can only be used on a rectangular clip window.
Clipping algorithms can be categorized into several types, primarily based on the dimensionality of the data they handle. The most common types include 2D clipping algorithms, such as the Cohen-Sutherland and Liang-Barsky algorithms, which are used for clipping line segments against rectangular windows. In contrast, 3D clipping algorithms, like the Sutherland-Hodgman and Weiler-Atherton algorithms, extend this concept to three-dimensional spaces for polygons. Additionally, there are specialized algorithms for clipping in graphics rendering, such as polygon clipping and curve clipping, which address specific geometric shapes and their intersections.
The cohen sutherland algo requires calculation of intersection of the line with the window edge.This direct calculation is avoided by performing a binary search for the intersection by always dividing the line at its midpoint.To implement it a parallel architecture is used and hardware division addition by 2 is very fast
To solve the Cohen-Sutherland line clipping algorithm, follow these steps: Define Clipping Window: Establish the boundaries of the clipping rectangle using a coordinate system. Assign Outcodes: For each endpoint of the line segment, compute an outcode that indicates its location relative to the clipping window (inside, left, right, above, below). Check Outcodes: If both endpoints have an outcode of 0000 (inside), the line segment is entirely inside. If the logical AND of the outcodes is not 0000 (indicating both points are outside the window in the same direction), the segment is entirely outside. Otherwise, proceed to the next step. Clip Line Segment: Use the outcodes to iteratively clip the line against the clipping window edges until the segment is either fully clipped or determined to be fully inside.
