**19-OCT-2017 PROJECT MOVED TO GITHUB**
OpSim is an open source Chemical Engineering Process Simulator with a user friendly drag-and-drop graphical user interface (GUI) and an underlying high performance simulation engine.
That project aims at providing a clean API, and the corresponding C++ implementation, able to generate demand for travel solutions (e.g., from JFK to PEK on 25-05-2009) according to characteristics (e.g., Willingness-To-Pay, preferred airline, etc).
A free rendered GUI library providing windowing and widgets for the easy creation of HUDs for games. It supports themes/skinning, XML-based configuration, and works with any graphics API or rendering engine including Axiom, Irrlicht, and SDL.NET.
