XMUSHORTN2 structure (directxpackedvector.h)
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.

void XMUSHORTN2( uint16_t _x, uint16_t _y) noexcept
Initializes a new instance of XMUSHORTN2
from two uint16_t
arguments.
This constructor initializes a new instance of XMUSHORTN2 from two
uint16_t
arguments.
void XMUSHORTN2( const uint16_t *pArray) noexcept
Initializes a new instance of XMUSHORTN2 from a two element uint16_t
array argument.

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.
