XMU555 union

A 4D vector with x-,y-, and z- components represented as 5 bit unsigned integer values, and the w-component as a 1 bit integer value.

For a list of additional functionality such as constructors and operators that are available using XMU555 when you are programming in C++, see XMU555 Extensions.

Syntax

C++


union XMU555 {
  union {
    struct {
      uint16_t x : 5;
      uint16_t y : 5;
      uint16_t z : 5;
      uint16_t w : 1;
      uint16_t v;
    };
  };
};

Members

x : 5: Unsigned 5-bit integer value in the range [0,31] describing the x-coordinate of the vector.
y : 5: Unsigned 5-bit integer value in the range [0,31] describing the y-coordinate of the vector.
z : 5: Unsigned 5-bit integer value in the range [0,31] describing the z-coordinate of the vector.
w : 1: A 1-bit integer value in the range [0,31] describing the w-coordinate of the vector.
v: Unsigned short representing the 4D vector.

Remarks

XMU555 can be loaded into instances of XMVECTOR by using XMLoadU555.

Instances of XMVECTOR can be stored into an instance of XMU555 with XMStoreU555.
