OpenVSP is a parametric aircraft geometry tool. OpenVSP allows the user to create a 3D model of an aircraft defined by common engineering parameters. This model can be processed into formats suitable for engineering analysis.
The predecessors to OpenVSP have been developed by JR Gloudemans and others for NASA since the early 1990's. In January 2012, OpenVSP was released as an open source project under the NOSA 1.3 license. The first open source version was 2.0.0.
OpenVSP is available under the terms of the NASA Open Source Agreement (NOSA) version 1.3. The complete terms of the license are specified in the LICENSE file.
OpenVSP relies on a variety of libraries and code made available by other authors. If you are a VSP user, you probably don't need to worry about this. Take this section as informational, providing credit where due.
If you wish to compile VSP or to use the VSP API, then you will need to know more. These dependencies fall into four categories: those assumed to be provided by the operating system; those that must be downloaded and installed by the developer; those that are bundled with OpenVSP, but the developer may want to use a different version installed on the system; and those that are bundled with OpenVSP.
