XMFLOAT4 structure

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.

Syntax


struct XMFLOAT4 {
  float x;
  float y;
  float z;
  float w;
};

Members

x

float value describing the x-coordinate of the vector.

y

float value describing the y-coordinate of the vector.

z

float value describing the z-coordinate of the vector.

w

float value describing the w-coordinate of the vector.

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.
