XMSHORTN2 structure

-description

A 2D vector for storing signed, normalized values as signed 16-bit integers (type int16_t).

For a list of more functionality such as constructors and operators that are available using XMSHORTN2 when you are programming in C++, see XMSHORTN2 Extensions.

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

-struct-fields

-field x

Signed integer in the range [-32767, 32767] describing the x coordinate of the vector.

-field y

Signed integer in the range [-32767, 32767] describing the y coordinate of the vector.

-field v

-field XMSHORTN2

TBD

-field operator=

TBD

-remarks

Those XMSHORTN2 constructors using floating point arguments require normalized input, which must be in the range of [-1.0.-1.0]. During instantiation, data is multiplied by 32767.0f, results are rounded, and then assigned to the appropriate members of XMSHORTN2.

You can use XMSHORTN2 to load instances of XMVECTOR from normalized values by using XMLoadShortN2, which divides each component 32767.0f, rounds the result, and then assigns the components to an XMVECTOR instance.

You can store XMVECTOR instances containing normalized values into XMSHORTN2 using XMStoreShortN2, which multiplies each component by 32767.0f, rounding the result, before assigning the values to the appropriate XMSHORTN2 members.

Namespace: Use DirectX::PackedVector

Platform Requirements

Microsoft Visual Studio 2010 or Microsoft Visual Studio 2012 with the Windows SDK for Windows 8. Supported for Win32 desktop apps, Windows Store apps, and Windows Phone 8 apps.
