Show hintHide hint
Remember to include the extra dimension.
3Question 3.
What do homogeneous coordinates allow us to do?
- Increase dimensionality
- Decrease computational efficiency
- Eliminate transformations
Show hintHide hint
Think about the benefits of having more dimensions.
4Question 4.

- True
- False
Show hintHide hint
What happens if you reverse the steps?
Question 5.
Given points A(2,3) and B(4,5), find the translation matrix to move A by (1,2) and apply it to A. What is the new homogeneous coordinate?
Show hintHide hint
Remember to apply the transformation as a matrix operation.
Question 6.
If a point (1,1) is rotated 90 degrees around the origin, what are its new coordinates in homogeneous form?
Show hintHide hint
Use the angle to set up the rotation matrix.
