  • 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.

    Stencil for Omnigraffle drawing tool (Mac & iPad) to enable architecture description views to be created for the TRAK Enterprise Architecture Framework (available on Sourceforge via the trak, trakmetamodel and trakviewpoints projects). Provides the set of shapes and connectors needed to create TRAK views to describe the enterprise, concepts, systems and how they're procured. Using the stencil in conjunction with the defining TRAK documents you can be up and creating architecture description in minutes. When used with OmniGraffle Pro it also provides the attributes for each object to capture extra information. When used on the iPad and with OmniGraffle on the Mac this information is preserved. This project is the master source of the stencil which is also distributed via OmniGraffle and Graffletopia. (Visio equivalent for TRAK at

  • Construct2D

    COmputational fluid dyNamics STRUctured grid CreaTor for 2D airfoils

    Construct2D is a grid generator designed to create 2D grids for CFD computations on airfoils. The grids are generated in Plot3D format. The only required input file is the set of coordinates defining the airfoil geometry, using the same format as XFoil, the popular vortex-panel code for airfoil analysis. Construct2D can create grids with O topology (recommended for airfoils with a blunt trailing edge) or C topology (recommended for airfoils with a sharp trailing edge). Now available in version 2.0: hyperbolic grid generation to create higher quality grids in a fraction of the time compared to elliptic grid generation. Elliptic grid generation is still available also. Smooth airfoil surface spacing is handled automatically with user-controlled clustering parameters. Also included is a visualizer written in Python with matplotlib.
