This is an online repository for architects + designers learning how to program in a three dimensional visual environment. I will use this repository as a resource for the workshop that will teach at MIT. Processing will be used as the programming environment and no prior programming experience is required for it.

Processing v1.0.1 can be downloaded from: http://processing.org/download/ In some of the examples I have used a camera library called 'PeasyCam'. Please download it from http://mrfeinberg.com/peasycam/. Installation instructions are given at this website. Both Mac and Windows versions are available.

The basic building blocks of programs—variables, expressions, assignment statements, and subroutine call statements—were covered in the previous chapter. Starting with this chapter, we look at how these building blocks can be put together to build complex programs with more interesting behavior. We are interested in the kind of complexity that can occur within a single subroutine. On this level, complexity is provided by control structures...
