FSEM 131: Lab 4

Due Thursday November, 15

Using the Processing language/environment fix and extend the provided program. Your code should use variables, loops and functions.

Run the provided program: copy and paste in your own processing sketch called flower.

The program produces the following image.

1. [8 pts] After reading the provided code, modify the code to create the same output but in a better style. Among other things you have to make the following updates. Don't forget to run and debug throughout.

declare and use a variable petalSize (intead of having a magic number throughout)
remove the duplicate/similar code by creating the petals using a loop (for/while your choice)
check your improved code work for a different numberOfPetals value
convert the code to interactive mode (using setup/draw) functions.

2. [2 pts] Once your done fixing the program style, change variable values to modify your flower look. For example below is a minimal change. I encourage you to be creative.

(The image has transparency: an alpha is used for the yellow.)

3. [4 pts] Add a stem and leaves of your design. Below is just a model.

4. [6 pt] Animate the flower so the petals turn around the pistil.
