Note

The math functions of the D3DX utility library are deprecated for Windows 8. We recommend that you use DirectXMath instead.

 

The math library provided by the D3DX utility library supplies functions to compute 3D mathematical operations. Each of the functions can take the same object as the passed [in] and returned [out] parameters. Also, out parameters are typically returned as return values, so that the output of one math function can be used as a parameter for another math function.

Many of the functions are implemented in d3dx9math.inl.

The 3D math application functions can be organized into the following groups.
