XMLoadFloat4x4A function (directxmath.h)

Loads an XMFLOAT4X4A into an XMVECTOR.

Syntax

XMMATRIX XM_CALLCONV XMLoadFloat4x4A(
  [in] const XMFLOAT4X4A *pSource
) noexcept;

Parameters

[in] pSource

Address of the XMFLOAT4X4A structure to load.

Return value

Returns an XMMATRIX loaded with the data from the pSource parameter.

Remarks

XMFLOAT4X4A is a row-major form of the matrix. This function could be used to read column-major data, but would then need to be transposed with XMMatrixTranpose before use in other XMMATRIX functions.

The members of the XMFLOAT4X4A structure (_11, _12, _13, and so on) are loaded into the corresponding members of the XMMATRIX.

Platform Requirements

Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
