XMMATRIX::XMMATRIX(FXMVECTOR,FXMVECTOR,FXMVECTOR,CXMVECTOR) function (directxmath.h)

Initializes a new instance of the XMMATRIX structure from four instances of XMVECTOR.

Initializes a new instance of the XMMATRIX structure from four instances of XMVECTOR Data Type.

Syntax

void XMMATRIX(
  FXMVECTOR R0,
  FXMVECTOR R1,
  FXMVECTOR R2,
  CXMVECTOR R3
) noexcept;

Parameters

R0

Instance of XMMATRIX used to initialize the first row of a new instance of XMMATRIX.

R1

Instance of XMMATRIX used to initialize the second row of a new instance of XMMATRIX.

R2

Instance of XMMATRIX used to initialize the third row of a new instance of XMMATRIX.

R3

Instance of XMMATRIX used to initialize the fourth row of a new instance of XMMATRIX.

Return value

None

Remarks

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

XMMATRIX mat;
XMVECTOR rows[4];
//...Initialize instances of XMVECTOR
for (int i=0;i<4;i++){
    for (int j=0;j<4;j++){
        mat.m[i][j]=rows[i].v[j];
    }
}

Or

XMMATRIX mat;
XMVECTOR rows[4];
//...Initialize instances of XMVECTOR
for (int i=0;i<4;i++){
    mat.r[i]=rows[i];
}
