TODO: Homework Use the code here as a start: – http://www.cse.wustl.edu/~gazihan/teaching/12s pring/se313/material/week5/hw/samplecode/ http://www.cse.wustl.edu/~gazihan/teaching/12s pring/se313/material/week5/hw/samplecode/ – It translates, then rotates (global to local) – Similarly, start with the code that you wrote last week (looking through the area between the two squares) Create a third square that moves between the two and rotates Like these screenshots here: http://www.cse.wustl.edu/~gazihan/teaching/12spring /se313/material/week5/hw/hwshots/ http://www.cse.wustl.edu/~gazihan/teaching/12spring /se313/material/week5/hw/hwshots/ 15.03.20124

TODO: Prepare for the lab Go over what we learned so far and come prepared for the lab that we will have next week – Simple understanding of geometric transformations The website has supplementary material about what we learned today (under week 5) – Should not be too hard if you understand the homework 15.03.20125
