Question

______ moves a view along the X-axis or Y-axis.

• A. Scale Animation
• B. Rotate Animation
• C. Translate Animation
• D. Alpha Animation

Hint:

Think of the term “Translation” in physics: it refers to translational motion, which means shifting positions from Point A to Point B without rotation.

Answer 1

The Correct Option is C

Step 1: Analyzing Affine Transformations in Computer Graphics:
To animate or reposition any graphical element on screen, the underlying graphic engine applies mathematical functions called affine transformations. The three principal transformations are: Translation, Rotation, and Scaling.

Step 2: Defining Each Animation Type:

• Scale Animation: Alters the dimensions of the view (stretching or compressing along $X$ or $Y$).
• Rotate Animation: Turns the view by a specific angular measurement ($\theta$) around a designated pivot coordinate.
• Translate Animation: Shifts the spatial coordinates of the object along a linear path, defined mathematically as: $$x_{\text{new}} = x_{\text{old}} + \Delta x \quad \text{and} \quad y_{\text{new}} = y_{\text{old}} + \Delta y$$ This matches the requirement of moving the view along the $X$-axis and/or $Y$-axis.

Step 3: Concluding the Right Choice:
Since “Translate” mathematically represents spatial shift without changing scale or orientation, Option (C) is the correct answer.
