XMFLOAT4 Constructor

Describes a 4D vector consisting of four single-precision floating-point values.

For a list of additional functionality such as constructors and operators that are available using XMFLOAT4 when you are programming in C++, see XMFLOAT4 Extensions.

Note

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

Overload list

Name	Description
XMFLOAT4 ()	Default constructor for XMFLOAT4. Default constructor for XMFLOAT4. Note This constructor is only available under C++.
XMFLOAT4 (const float*)	Initializes a new instance of XMFLOAT4 from a four element float array argument. This constructor initializes a new instance of XMFLOAT4 from a from a four element float array argument. Note This constructor is only available under C++.
XMFLOAT4 (float, float, float, float)	Initializes a new instance of XMFLOAT4 from four float arguments. This constructor initializes a new instance of XMFLOAT4 from four float arguments. Note This constructor is only available under C++.

Remarks

XMFLOAT4 can be loaded into instances of XMVECTOR by using XMLoadFloat4.

Instances of XMVECTOR can be stored into an instance of XMFLOAT4 with XMStoreFloat4.
