In the previous chapter, we installed openFrameworks and learned how to build and run its example projects. It's time to start our own project! So, in this chapter, we are going to develop a sketch of the video synthesizer and explore the basics of 2D graphics with openFrameworks.
We will cover the following topics:
Creating a new project with Project Generator
openFrameworks project's structure
Setting up screen size and frame rate
Drawing geometric primitives, such as lines, triangles, and circles
Drawing patterns from geometric primitives
