In 3D computer graphics, which geometric transformation maps a 3D scene onto a 2D viewing plane from specific directions and camera distances?
In 3D computer graphics, which geometric transformation maps a 3D scene onto a 2D viewing plane from specific directions and camera distances?
Multiple Choice Options
- A✓ Correct Option
Projection (Orthographic / Perspective)
- B
Translation
- C
Rotation
- D
Scaling
Detailed Technical Solution & Explanation
Projection transforms 3D coordinate space onto a 2D projection plane (the viewport/screen). Perspective projection simulates human vision with foreshortening based on camera distance, while orthographic projection maintains parallel lines.
Option Analysis:
•
Option A (Projection (Orthographic / Perspective)): Correct. Maps 3D space to a 2D view surface from given directions and distances.
•
Option B (Translation): Moves an object rigidly in space without changing view angle or dimension.
•
Option C (Rotation): Reorients an object around a specified coordinate axis.
•
Option D (Scaling): Enlarges or shrinks object geometry.
