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.
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 XMFLOAT4X4
m[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.
