About Open Vsp

OpenVSP is a parametric aircraft geometry tool that creates 3D aircraft models defined by common engineering parameters for processing into formats suitable for engineering analysis. It is available through a GUI, via an API for use by other programs, or in batch mode with no user interaction. Compiling the software or using the API requires developer setup, including a C++ compiler and CMake.

Key features

  • Create 3D aircraft models from engineering parameters
  • Process models into formats for engineering analysis
  • Access via GUI, API, or batch mode without interaction
  • Create user-defined components with embedded AngelScript
  • Compile headless targets without graphics libraries installed
  • Build Python API interface using SWIG and Python
Best for: Engineers and developers who need parametric aircraft geometry for engineering analysis.
Good for
  • Models defined by common engineering parameters for analysis workflows
  • Supports GUI, programmatic API access, and headless batch mode
  • Distributed under NASA Open Source Agreement version 1.3
Watch out for
  • Compiling or using the API requires managing developer dependencies
  • Graphical builds require graphics libraries such as OpenGL
  • Building the Python API module requires SWIG and Python
