How do you clip line using Cohen-Sutherland algorithm?

Pseudocode

  1. Step 1 : Assign a region code for two endpoints of given line.
  2. Step 2 : If both endpoints have a region code 0000 then given line is completely inside and we will keep this line.
  3. Step 3 : If step 2 fails, perform the logical AND operation for both region codes.
  4. Step 4 : Repeat step 1 for all lines.

What is clipping explain Cohen-Sutherland algorithm for clipping with example?

Share. Line clipping is a clipping concept in which lines that lies outside the clipping window is removed from the clip region. As a result, only lines which is inside the view plane are visible. Cohen Sutherland Algorithm is one of the popular line clipping algorithm used for the purpose.

Which is the best line clipping algorithm?

Cohen-Sutherland Line Clipping Algorithm : In which 2-D space (in which line resides) is divided into 9 regions and then the lines and portions of lines which are visible in the central region of interest are determined efficiently.

What is the disadvantage of Cohen Sutherland line clipping?

Limitations of Cohen-Sutherland clipping algorithm 1) Clipping window region can be rectangular in shape only and no other polygonal shaped window is allowed. 2) Edges of rectangular shaped clipping window has to be parallel to the x-axis and y-axis.

What are the advantage of Cohen-Sutherland line clipping?

Advantage of Cohen Sutherland Line Clipping It calculates end-points very quickly and rejects and accepts lines quickly. It can clip pictures much large than screen size.

What is the aim of line clipping algorithms?

The aim of the line clipping algorithm is to find a part of the given line p which is inside of the given polyhedron P, see Fig. 1.1. Algorithms for line clipping are mostly restricted to line clipping against convex polyhedron.

What are the advantage of Cohen Sutherland line clipping?

Advantage of Cohen Sutherland Line Clipping: It calculates end-points very quickly and rejects and accepts lines quickly. It can clip pictures much large than screen size.

What are the advantages of Cohen-Sutherland line clipping?

How does Cohen Sutherland algorithm work?

The Cohen–Sutherland algorithm is a computer-graphics algorithm used for line clipping. The algorithm divides a two-dimensional space into 9 regions and then efficiently determines the lines and portions of lines that are visible in the central region of interest (the viewport).
