Hello and welcome to Day 7 of CS First Art! Today, you will create a project, or pieceof software, that an architect could use to quickly prototype a building. An architectis a professional building designer. They design structures like houses, bridges, schools, museums,and sports arenas. Architects rely on software built by computer scientists tohelp them visualize, test, and communicate about their designs.
In architecture, as well as in other forms of art and design, simple shapes combine tomake bigger, more complex shapes or structures. Take a look at a few buildings known throughoutthe world for their architectural design. The White House is made up of triangles and rectangles.
Once complete, today’s project will allow you and others to build interesting buildingsusing a variety of simple, stamped shapes. You will use a “repeat until” loop tocreate this project. The “repeat until” loop is similar toa “repeat” loop, except instead of stopping after a specified number of times, it keepsgoing until a particular condition is true.
Remember, a condition in computer science is something that must be true in order forsomething else to happen. For example, to get your friend Jo’s attention,you will repeat calling her name until she answers you. Her answering you is the “condition”that must be true, and the something that will happen is that you stop calling. Youmight call once, or you might call 10 times! How many times depends on the condition. Youwill repeat calling Jo’s name until she answers.
The art project you see here also uses a “repeat until” loop. It repeats drawing silk weaveuntil the user stops holding the mouse. Today’s project uses repeat until to makea stamp follow the mouse pointer *until* the mouse is clicked.
