Random shape. Drift to a new position. Reduce the amount of green.
Random dots located on a circle, purify color, Benz symbol.
Practice: red-blue, spam-circle, rectangle limitations. Review reading.
Analysis of functions - signatures and check-expects. Structure practice.
The drifter animation that takes little or big steps while moving.
Random numbers. Gas gauge. Graphing in people coordinates.
Additional review exercises.
Make a 300x700 gradient that goes from “MediumVioletRed” at the top to “LimeGreen” at the bottom. Include at least three check-expects. Create a function purple-ize: image -> image that takes in an image and changes every pixel’s color to the closest “purple” color. Say purple is red and blue, so the nearest purple color corresponds to whichever component has more. Example: the nearest purple color to (220,50,80) is (220,50,220), and the nearest purple color to (30,40,50) is (50,40,50).
Major topics missed on Chapter 20 test: randomness, consistent signatures for big-bang, good testing.
