XMUSHORTN2 structure

A 2D vector for storing unsigned, normalized values as unsigned 16-bit integers, (type uint16_t).

For a list of more functionality such as constructors and operators that are available using XMUSHORTN2 when you are programming in C++, see XMUSHORTN2 Extensions.

Syntax

struct XMUSHORTN2 {
  uint16_t x;
  uint16_t y;
};

Members

x

Unsigned integer in the range [0, 65536] describing the x-coordinate of the vector.

y

Unsigned integer in the range [0, 65536] describing the y-coordinate of the vector.

Remarks

Those XMUSHORTN2 constructors using floating point arguments require normalized input, which must be in the range of [0.0.-1.0]. During instantiation, data is multiplied by 65535.0f, results are rounded, and then assigned to the appropriate members of XMUSHORTN2.

You can use XMUSHORTN2 to load instances of XMVECTOR from normalized values by using XMLoadShortN4, which divides each component 65535.0f, rounds the result, and then assigns the components to an XMVECTOR instance.

You can store XMVECTOR instances containing normalized values into XMUSHORTN2 using XMStoreShortN4, which multiplies each component by 65535.0f and rounds the result before assigning the values to the appropriate XMUSHORTN2 members.
