Specific Objective

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

• understand the concept of polygon rendering
• explain different methods of polygon rendering with advantages and disadvantages
• write algorithm of Gouraud shading and Phong shading

Teaching Materials

• Laptop
• Presentation slide
• Projector
• Whiteboard and marker

Teaching Learning Activities

1. I will begin the class by asking students what they know about polygon rendering.
2. Then begin the topic by defining polygon rendering is a fundamental technique in computer graphics used to represent three-dimensional objects in a two-dimensional space.
3. Discuss what are the components that involves to create realistic shading.
4. Discuss different methods for polygon rendering.
5. Present the figure of different methods of polygon rendering:Constant shading, Gouraud shading and Phong shading.
6. Ask students what differences they find out in those picture.
7. Illustrate each algorithm with examples and diagrams to demonstrate their effectiveness.
8. Ask students to differentiate among the basic illumination model.
9. Show the comparison table of different basic illumination model
10. Ask students if there is any confusion on today's topic and provide guidance and assistance if needed.

Assessment

1. Describe basic illumination model.

2. Compare and contrast sepcular highlights and diffuse reflection with figure.
