Question

Arrange the $2-D$ viewing transformation pipeline.

1. Convert world-coordinates to viewing coordinates
2. Map viewing coordinates to normalized viewing coordinates using window - viewpoint specifications
3. Construct world - coordinates scene using modeling - coordinates transformations
4. Map normalized viewpoint to device coordinates

Choose the correct answer from the options given below:

• A. $\text{IV, III, II, I}$
• B. $\text{IV, III, I, II}$
• C. $\text{IV, I, II, IV}$
• D. $\text{II, III, I, IV}$

Answer 1

Correct Order:

1. Construct world-coordinates scene using modeling-coordinates transformations

2. Convert world-coordinates to viewing coordinates

3. Map viewing coordinates to normalized viewing coordinates using window–viewport specifications

4. Map normalized viewport to device coordinates

Final Answer:

3 → 1 → 2 → 4
