XMBYTE4 union

A 4D vector where each component is a signed integer, 8-bits (1 byte) in length.

For a list of additional functionality such as constructors and operators that are available using XMBYTE4 when you are programming in C++, see XMBYTE4 Extensions.

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

Syntax


union XMBYTE4 {
  union {
    struct {
      uint8_t x;
      uint8_t y;
      uint8_t z;
      uint8_t w;
    };
    uint32_t v;
  };
};

Members

x

Signed 8-bit integer value in the range [-127, 127] describing the x-coordinate of the vector.

y

Signed 8-bit integer value in the range [-127, 127] describing the y-coordinate of the vector.

z

Signed 8-bit integer value in the range [-127, 127] describing the z-coordinate of the vector.

w

Signed 8-bit integer value in the range [-127, 127] describing the w-coordinate of the vector.

v

Unsigned 32-bit integer representing the 4D vector.

Remarks

XMBYTE4 can be loaded into instances of XMVECTOR by using XMLoadByte4.

Instances of XMVECTOR can be stored into an instance of XMBYTE4 with XMStoreByte4.
