XMFLOAT4X4 union

A 4*4 floating point matrix.

For a list of additional functionality such as constructors and operators that are available using XMFLOAT4X4 when you are programming in C++, see XMFLOAT4X4 Extensions.

Note  See DirectXMath Library Type Equivalences for information about equivalent D3DDECLTYPE, D3DFORMAT, and DXGI_FORMAT objects.

Syntax


union XMFLOAT4X4 {
  union {
    struct {
      float _11;
      float _12;
      float _13;
      float _14;
      float _21;
      float _22;
      float _23;
      float _24;
      float _31;
      float _32;
      float _33;
      float _34;
      float _41;
      float _42;
      float _43;
      float _44;
    };
    float m[4][4];
  };
};

Members

_11

An element of the matrix.

_12

An element of the matrix.

_13

An element of the matrix.

_14

An element of the matrix.

_21

An element of the matrix.

_22

An element of the matrix.

_23

An element of the matrix.

_24

An element of the matrix.

_31

An element of the matrix.

_32

An element of the matrix.

_33

An element of the matrix.

_34

An element of the matrix.

_41

An element of the matrix.

_42

An element of the matrix.

_43

An element of the matrix.

_44

An element of the matrix.

m

A 4*4 array representing the matrix.

Remarks

Scalar members of XMFLOAT4X4 are of the form _RowCol, and provide one based indexing, where Row specifies the one's based matrix row (running from 1 to 4), and Col specifies the one's based matrix column (running from 1 to 4).

The two dimensional 4*4 array member of XMFLOAT4X4, m, provides zero based indexing of the structure's matrix. When accessing XMFLOAT4X4m[Row,Col], Row can run from 0 to 3 and Col can run from 0 to 3.

XMFLOAT4X4 can be loaded into instances of XMVECTOR by using XMLoadFloat4x4.

Instances of XMVECTOR can be stored into an instance of XMFLOAT4X4 with XMStoreFloat4x4.
