LIANG BARSKY LINE CLIPPING ALGORITHM PDF

The Liang-Barsky algorithm is a line clipping algorithm. This algorithm is more efficient than Cohen—Sutherland line clipping algorithm and can be extended to 3-Dimensional clipping. This algorithm is considered to be the faster parametric line-clipping algorithm. The following concepts are used in this clipping:. When the line is parallel to a view window boundary, the p value for that boundary is zero. Parameters t 1 and t 2 can be calculated that define the part of line that lies within the clip rectangle.

The Liang-Barsky algorithm is a line clipping algorithm. This algorithm is more efficient than Cohen—Sutherland line clipping algorithm and can be extended to 3-Dimensional clipping.

This algorithm is considered to be the faster parametric line-clipping algorithm. The following concepts are used in this clipping:. When the line is parallel to a view window boundary, the p value for that boundary is zero. Parameters t 1 and t 2 can be calculated that define the part of line that lies within the clip rectangle.

Otherwise, the endpoints of the clipped line are calculated from the two values of parameter t. This algorithm is presented in the following code. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.

Liang Barsky Line Clipping Algorithm in C and C++

Login Now. Liang — Barsky line clipping algorithm is faster line clipper algorithm based on analysis of the parametric equation of a line segment. Using these equations Cyrus and Beck developed an algorithm that is generated more efficient than the Cohen Sutherland algorithm. If there is a segment of line inside the clip region, a sequence of infinite line intersections must go entering, entering, exiting, and exiting as shown in figure Find answer to specific questions by searching them here.
