All questions carry equal marks.
Attempt all the questions.
1. What is a random scan display system? Draw its block diagram and explain it in detail.
2. What do you mean by homogeneous coordinates? Explain it with equation and practical application.
3. Explain the following terms with practical applications.
a. 3D Mirror
b. 2D Rotation
4. Explain in detail about circle clipping algorithm. Where do you require circle clipping algorithm?
5. How can you draw circle? Explain with algorithm.
6. Explain in detail about polygon table. How can you apply in the case of computer animation?
7. What is a polygon mesh? Explain the application of polygon mesh with example.
8. Justify that hidden surface removal is required in computer graphics. Explain in detail about depth buffer method.
OR
Explain in detail about scan line method. Just that it is better than depth buffer method.
