Overview {#mathfu_overview}

[MathFu][] is a C++ math library developed primarily for games focused on simplicity and efficiency.

It provides a suite of [vector][], [matrix][] and [quaternion][] classes to perform basic [geometry][] suitable for game developers. This functionality can be used to construct geometry for graphics libraries like [OpenGL][] or perform calculations for animation or physics systems.

[MathFu] can be downloaded from GitHub or the releases page.

Important: MathFu uses submodules to reference other components it depends upon so download the source using:

    git clone --recursive https://github.com/google/mathfu.git

Functionality

Each [vector][], [matrix][] and [quaternion][] class implements basic arithmetic operators (addition, subtraction, multiplication, division) in addition to simple [linear algebra][] operators (e.g dot product, cross product, inverse, slerp).

Optimization

[MathFu][] is optimized using [SIMD][] instructions (including [NEON][] for ARM and [SSE][] for [x86][] architectures). [SIMD][] optimization is enabled by default based upon the target platform and compiler options used to build a project. In addition, [MathFu][] provides compile time options to modify code generation, see [Build Configurations][] for more details.

Supported Platforms

[MathFu][] has been tested on the following platforms:

Android
[Linux][] (x86_64)
[OS X][]
[Windows][]

This library is entirely written in C++ with the exception of some conditionally enabled compiler intrinsics and some workarounds for different compiler quirks, which means that it should work with either no or little modification on any platform that has a C++ compiler.
