On scaling a 2D graphical primitive with scaling factors and where , the resulting transformation is called:
Multiple Choice Options
- A
Uniform scale
- B✓ Correct Option
Non-uniform scale
- C
Perspective scale
- D
None of the above
Detailed Technical Solution & Explanation
When scaling transformations apply unequal scalar multipliers along different coordinate dimensions ( in 2D, or in 3D), the geometric proportions of the object are distorted. This transformation is termed Non-uniform scaling (or differential scaling). In contrast, uniform scaling requires .
Option Analysis:
•
Option A (Uniform scale): Incorrect; requires equal scaling factors .
•
Option B (Non-uniform scale): Correct; unequal scaling factors generate non-uniform scaling.
•
Option C (Perspective scale): Incorrect; perspective transformation involves depth division in 3D viewing projections.
•
Option D (None of the above): Incorrect.
