Multiple Choice Options
- A
Uniform scale
- B✓ Correct Option
Non-uniform scale
- C
Not possible
- D
Scalable measure
Detailed Technical Solution & Explanation
In computer graphics geometric transformations:
•
Uniform Scaling: When the scaling factors along all coordinate axes are equal (). The object changes size uniformly while strictly preserving its original aspect ratio and shape proportions.
•
Non-Uniform (Differential) Scaling: When the scaling factors along the coordinate axes are different (). The object is stretched or compressed along one axis relative to another, altering its aspect ratio and distorting its shape.
Option Analysis:
•
Option A (Uniform scale): Incorrect; occurs only when .
•
Option B (Non-uniform scale): Correct; by definition, scaling with unequal scaling factors () produces non-uniform scaling.
•
Option C (Not possible): Incorrect; non-uniform scaling is a standard transformation in graphics pipelines.
•
Option D (Scalable measure): Incorrect; not a recognized geometric transformation term.
