Use the Liang-Barsky algorithm to clip the lines in Fig. 5-19.
Understand the Problem
The question is asking to apply the Liang-Barsky algorithm to clip the lines depicted in Figure 5-19. This involves determining which portions of the lines remain within the defined boundaries after clipping.
Answer
Clip line segments using intersections with boundaries.
Clip each line segment using the Liang-Barsky algorithm based on intersections with the clipping boundaries to determine visible portions.
Answer for screen readers
Clip each line segment using the Liang-Barsky algorithm based on intersections with the clipping boundaries to determine visible portions.
More Information
The Liang-Barsky algorithm calculates the entry and exit points of a line segment with respect to the clipping boundary using parametric equations, making it more efficient than the Cohen-Sutherland algorithm.
Tips
Common mistakes include incorrect calculation of parameter values and misinterpretation of intersection points.
