XMFLOAT3X4::XMFLOAT3X4(constfloat*) function (directxmath.h)

  • Article

Constructs an XMFLOAT3X4 from a 12-element array of float values.

Syntax

void XMFLOAT3X4(
  const float *pArray
) noexcept;

Parameters

pArray

Type: const float *

A pointer to a 12-element array of float values. The array specifies the value of each member of the new matrix.

Return value

None

Remarks

The matrix elements in pArray should be in row-major order. These two pseudocode examples illustrate how this constructor operates.

DirectX::XMFLOAT3X4 mat;
mat._11 = pArray[0];
mat._12 = pArray[1];
mat._13 = pArray[2];
mat._14 = pArray[3];
mat._21 = pArray[4];
mat._22 = pArray[5];
mat._23 = pArray[6];
mat._24 = pArray[7];
mat._31 = pArray[8];
mat._32 = pArray[9];
mat._33 = pArray[10];
mat._34 = pArray[11];

DirectX::XMFLOAT3X4 mat;
mat.m[0, 0] = pArray[0];
mat.m[0, 1] = pArray[1];
mat.m[0, 2] = pArray[2];
mat.m[0, 3] = pArray[3];
mat.m[1, 0] = pArray[4];
mat.m[1, 1] = pArray[5];
mat.m[1, 2] = pArray[6];
mat.m[1, 3] = pArray[7];
mat.m[2, 0] = pArray[8];
mat.m[2, 1] = pArray[9];
mat.m[2, 2] = pArray[10];
mat.m[2, 3] = pArray[11];
