XMLoadFloat3x4A function (directxmath.h)

  • Article

Loads an XMFLOAT3X4A into an XMMATRIX.

Syntax

XMMATRIX XM_CALLCONV XMLoadFloat3x4A(
  const XMFLOAT3X4A *pSource
) noexcept;

Parameters

pSource

Type: const XMFLOAT3X4A *

Pointer to the constant XMFLOAT3X4A structure to load. This argument must point to cached memory.

Return value

Type: XMMATRIX

An XMMATRIX loaded with the data from the pSource argument.

This function performs a partial load of the returned XMMATRIX. For more info, see Getting started (DirectXMath).

Remarks

XMFLOAT3X4A is a row-major form of the matrix. XMLoadFloat3x4A could be used to read column-major data, but that would then need to be transposed with XMMatrixTranspose before use in other XMMATRIX functions.
