WaveDrag and WingBody define the vehicle geometry internally in terms of a wire frame mesh. PanAir reads a wire frame mesh as part of its input file. All of these programs were developed long before the definition of the Langley Wireframe Geometry Standard (LaWGS) and have their own input schemes. If you have prepared an input case for WaveDrag, WingBody, or PanAir, you would certainly like to visualize it, either as three-view or perspective. But these visualization programs require LaWGS input.

Some simple conversion programs come to your rescue. The program wd2wgs takes an input file for WaveDrag and produces a file called wd.wgs that may be used as input to 3view or hlp or wgs2wrl. A similar program called wb2wgs converts an input file for WingBody into a file called wb.wgs. Yet another program called a5022wgs converts the input file for PanAir into a file called a502.wgs. The programs hlp or 3view may then be used to make picturs of the vehicle configuration. The program wgs2wrl may be used to convert the objects into a VRML world for viewing with an appropriate browser. Still another program called hab2wgs takes old input decks from the Gentry hypersonic arbitrary-body program and converts the geometry data to wgs. Since HABP allows networks with different numbers of points per column, not all HABP decks can be converted.
