Question 1.
What is the scaling factor that would double the size of an object in 2D?
Show hintHide hint
Think of how scaling works with size adjustments.
Question 2.
What does the '1' represent in the 2D scaling matrix?
Show hintHide hint
Consider the definition of homogeneous coordinates.
3Question 3.
What does scaling in 2D allow you to do?
- Increase shape size
- Alter proportions
- Change color
Show hintHide hint
Focus on the defining characteristics of scaling.
4Question 4.
Is scaling linear?
- True
- False
Show hintHide hint
Remember the properties of linear transformations.
Question 5.
A rectangle with coordinates (1, 2), (1, 4), (3, 4), and (3, 2) is scaled by factors of (2, 3) along the x-axis and y-axis. What are the new coordinates?
Show hintHide hint
Apply the scaling factors to each coordinate individually.
Question 6.
Consider a cube centered at the origin with vertices at (-1, -1, -1) and (1, 1, 1). If it is scaled by 2 on the x-axis and 0.5 on the z-axis, what will be the new coordinates for the vertices?
Show hintHide hint
Calculate new vertex positions considering the scaling for each axis.
