 Jet framework is a fluid simulation engine SDK for computer graphics applications that was created by Doyub Kim as part of the book, ["Fluid Engine Development"](https://www.crcpress.com/Fluid-Engine-Development/Kim/p/book/9781498719926). The code is built on C++11 and can be compiled with most of the commonly available compilers such as g++, clang++, or Microsoft Visual Studio. Jet currently supports macOS (10.10 or later), Ubuntu (14.04 or later), and Windows (Visual Studio 2015 or later). Other untested platforms that support C++11 also should be able to build Jet. The framework also provides Python API for faster prototyping.
