DirectXMath programming guide
DirectXMath provides a math solution optimized for Windows.
In this section
||The DirectXMath Library implements an optimal and portable interface for arithmetic and linear algebra operations on single-precision floating-point vectors (2D, 3D, and 4D) or matrices (3×3 and 4×4).
||The DirectXMath library is based on the XNA Math C++ SIMD library version 2.04. Here we describe how DirectXMath differs from XNA Math and how DirectXMath versions differ.
||This overview describes the changes required to migrate existing code using the XNA Math library to the DirectXMath library.
|Working with D3DXMath
||D3DXMath is a math helper library for Direct3D applications.
||This topic describes optimization considerations and strategies with the DirectXMath Library.
||This topic describes the internal design of the DirectXMath library.
