No. of Students: 20

Specific Objective

At the end of this lesson students will be able to:

• understand the concept of line clipping in computer graphics
• familiarize with the principles of Cohen-Sutherland line clipping algorithm
• apply line clipping algorithms to remove lines outside a defined region

Teaching Materials

• Laptop
• Presentation slide
• Projector
• Whiteboard and marker

Teaching Learning Activities

1. At first I will ask students what they know about line clipping.
2. Then define line clipping as the process of determining which parts of a line lie inside or outside a specified region.
3. Discuss the importance of line clipping in various graphics applications.
4. Introduce basic line clipping techniques and their relevance in rendering scenes.
5. Present line clipping algorithms; Cohen-Sutherland algorithms.
6. Discuss the principles behind Cohen-Sutherland line clipping algorithm with their specific applications.
7. Illustrate the algorithm with examples and diagrams to demonstrate their effectiveness.
8. Ask students if there is any confusion on today's topic and provide guidance and assistance if needed.

Assessment

1. Explain the concept of line clipping and discuss its significance in computer graphics.

2. Write an algorithm for Cohen-Sutherland line clipping.
