Fityk is a program for nonlinear fitting of analytical functions (especially peak-shaped) to data. There are also people using it to remove the baseline from data, or to display data only.
It is usually used to analyze experimental data (crystallography, chromatography, photoluminescence and photoelectron spectroscopy, infrared and Raman spectroscopy, etc.).
The software comes as C++ libfityk library (with Python bindings), wxWidgets-based GUI and readline-based CLI.

Wykobi is an efficient, robust and simple to use multi-platform 2D/3D computational geometry library. Wykobi provides a concise, predictable, and deterministic interface for geometric primitives and complex geometric routines using and conforming to the ISO/IEC 14882:2003 C++ language specification.
The design and structure of Wykobi lends itself to easy and seamless integration into projects of any scale that require a robust yet efficient 2D/3D computational geometry back-end.
