There's also openFrameworks: <a href="http://www.openframeworks.cc" rel="nofollow">http://www.openframeworks.cc</a><p>Some major differences:<p>- Cinder is more "C++y", i.e. more use of templates, boost, etc... openFrameworks opts for more "C with classes" approach, which makes it resemble processing a bit more.<p>- Cinder uses system libs, openFrameworks tends to use third party libs that it wraps into its own API. This puts Cinder closer to the OS on windows/mac, but means that oF has linux support.<p>From personal view, it seems like more agencies use Cinder while more independant devs use openframeworks, but that really doesn't say anything of the frameworks themselves, more the communities.
