2 cards from this section. Quick, good the night before a test.
What is a transformation?
Think about how we move or resize objects.
Define what a matrix is in the context of transformations.
Consider how information can be organized in a grid.
What is the term for combining transformations through matrix multiplication?
Think about how you combine steps.
True or False: The order of operations does not matter when performing transformations with matrices.
Consider a situation where changing the order might lead to different results.
A cube at position (2, 2, 2) is translated to (4, 4, 4) and then scaled by a factor of 2. What is the final position of a vertex from (2, 2, 2)?
Remember to first apply the translation, then scale the new coordinates.
Given a matrix representing a rotation of 90 degrees around the z-axis, apply this to point (1, 0, 0) and provide the new coordinates.
Use the rotation matrix for z-axis to find the transformed coordinates.
