The **Ti**GL **G**eometry **L**ibrary can be used for the computation and processing of aircraft geometries 

stored inside [CPACS](https://github.com/DLR-LY/CPACS) files. TiGL 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.
