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 modern C++ idioms.

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.
