In 2D computer graphics transformations, what sign of rotation angle rotates an object in the clockwise direction?
Multiple Choice Options
- A
Positive Value
- B✓ Correct Option
Negative Value
- C
Value less than 180 degree
- D
All of the above
Detailed Technical Solution & Explanation
In 2D computer graphics transformation conventions, rotation angles are measured relative to the positive X-axis. By standard mathematical right-hand convention, positive angles rotate an object counter-clockwise, whereas negative angles rotate an object clockwise.
Option Analysis:
•
Option A (Positive Value): Incorrect. Rotates counter-clockwise.
•
Option B (Negative Value): Correct. Negative angular values rotate clockwise.
•
Option C (Value less than 180 degree): Incorrect.
•
Option D (All of the above): Incorrect.
