Level: Bachelor 6th sem
Unit: Five
Time: 50 min
No. of Students:
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 in those pictures.
7. Explain the concept of constant shading.
8. Make a figure by joining different polygons and explain after finding intensity value where to shade.
9. Discuss the advantages and disadvantages of constant shading.
10. Discuss why Gouraud shading came in use.
11. Draw the figure(triangle with scanline) in the whiteboard and explain how to interpolate the value.
12. Explain Gouraud shading algorithm with figure.
13. Discuss the advantages and disadvantages of Gouraud shading.
14. Explain Phong shading by comparing it with the concept of Gouraud shading.
15. Describe the algorithm of Phong shading with figure.
16. Discuss the advantages and disadvantages of Phong shading.
17. 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.
