ofxAwesomiumPlus is an addon for openFrameworks. It works as an interface between Awesomium and openFrameworks. This addon was built on top of an existing one (ofxAwesomium) because it was too limited to use it for the project I was working on at the moment. This addon gives you the ability to easily set up an interface for your application using HTML and make it interact with you c++ codebase. In the picture above you can see how you can combine openFrameworks elements with the HTML UI.
This is an open source c++ framework with a lot of features aimed towards creative applications. I use this framework to work with OpenCV for the Computer Vision technology. Read more about this framework on their website and give it a shot. I found it really easy to work with and the community is great.
