  • OpenFrames Icon


    Real-time interactive 3D graphics API for scientific simulations

    OpenFrames is an Application Programming Interface (API) that provides the ability to add interactive 3D graphics to any scientific simulation. A simulation developer can use OpenFrames to specify what they want to visualize, without having to know any details of computer graphics programming. Visualizations created using OpenFrames are cross-platform, hardware accelerated with OpenGL, and designed specifically to minimize computational overhead. They can be embedded within an existing GUI framework (e.g. Qt, wxWidgets, Winteracter) or created in independent OS-native windows. The OpenFrames API itself is written in C++, and bindings are available for C and Fortran.
