Processing: Creative Coding and Computational Art

In laying out the neighborhood, I used the previous house’s x and w positions to ensure
that the houses lined up properly, but also didn’t overlap.
In spite of the sketch’s length (when the four classes are added), the object-oriented structure
adds organization and (reusable) modularity to the code, as compared to a long series
of function calls. In addition, the OOP structure provides a logical framework in which to
add new features to the entire neighborhood, the House class, or any of the component
classes. Really take your time going through (and playing) with this example. I also suggest
trying to reimplement some of the internal drawing methods. For example, the cathedral
roof could be drawn with Processing’s triangle() function, and the dome roof could be
created with the bezier() or curve() function. Changing the internal implementation of
a class, if done properly, should have no effect on how you use the class. In addition (if
you’re feeling ambitious), you could even try to apply a tessellated texture as a skin to
some of the houses.
