XMUNIBBLE4 union

A 4D vector with four unsigned 4-bit integer components.

For a list of additional functionality such as constructors and operators that are available using XMUNIBBLE4 when you are programming in C++, see XMUNIBBLE4 Extensions.

Syntax

C++


union XMUNIBBLE4 {
  union {
    struct {
      uint16_t x : 4;
      uint16_t y : 4;
      uint16_t z : 4;
      uint16_t w : 4;
      uint16_t v;
    };
  };
};

Members

x : 4: Unsigned 4-bit integer value in the range [0,15] describing the x-coordinate of the vector. The 4-bit x component.
y : 4: Unsigned 4-bit integer value in the range [0,15] describing the y-coordinate of the vector. The 4-bit x component.
z : 4: Unsigned 4-bit integer value in the range [0,15] describing the z-coordinate of the vector. The 4-bit x component.
w : 4: Unsigned 4-bit integer value in the range [0,15] describing the w-coordinate of the vector. The 4-bit x component.
v: Unsigned short representing the 4D vector in a packed format.

Remarks

XMUNIBBLE4 can be loaded into instances of XMVECTOR by using XMLoadUNibble4.

Instances of XMVECTOR can be stored into an instance of XMUNIBBLE4 with XMStoreUNibble4.
