tigl Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies
  4. tigl-3.0.0.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

The TiGL Geometry Library can be used for the computation and processing of aircraft geometries stored inside 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.
