TiGL

TiGL is an open source project for computation and processing of aircraft geometries developed by German Aerospace Center.

TiGL Geometry Library offers many geometry related functions such as

• Point retrieval functions to compute points on the aircraft surface
• Intersection functions to compute the intersection of the aircraft with planes
• Export functions for standard CAD file formats (STEP + IGES) or mesh formats, including VTK, Collada, and STL.

The TiGL library uses the OpenCASCADE CAD kernel to represent the airplane geometry by NURBS surfaces. The library provides external interfaces for C, C++, Python, Java, MATLAB, and FORTRAN.

TiGL is shipped with the Qt based TiGL Viewer for visualizing aircraft geometries or viewing CAD files.
