XMFLOAT4X4::XMFLOAT4X4(constfloat*) function (directxmath.h)

  • Article

Initializes a new instance of the XMFLOAT4X4 structure from a sixteen element float array.

Initializes a new instance of the XMFLOAT4X4 structure from a sixteen element float array.

Note  This constructor is only available under C++.
 

Syntax

void XMFLOAT4X4(
  const float *pArray
) noexcept;

Parameters

pArray

Address of a 16 element float array, specifying the value of each member of a new instance of XMFLOAT4X4.

Return value

None

Remarks

The matrix elements are stored in pArray in row-major order.

The following two pseudocode examples demonstrate the operation of this constructor:


   XMFLOAT4X4 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];
   mat._41 = pArray[12];
   mat._42 = pArray[13];
   mat._43 = pArray[14];
   mat._44 = pArray[16];

Or


    XMFLOAT4X4 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];
   mat.m[3,0] = pArray[12];
   mat.m[3,1] = pArray[13];
   mat.m[3,2] = pArray[14];
   mat.m[3,3] = pArray[16];
