is ofBeginShape() in openFrameworks. The openFrameworks wiki includes an article for people coming to openFrameworks from Processing. Another similar project is Cinder, which is also a C++ library framework for creative programming. The primary difference is that openFrameworks has a larger number of dependencies on open source libraries, allowing advanced programmers more control and transparency, while Cinder is more dependent on libraries built into the operating systems it sits on top of, which generally means updates and bug fixes are more frequent and reliable with openFrameworks.
