XMUDEC4 structure (directxpackedvector.h)
A 4D vector with x-,y-, and z- components represented as 10 bit unsigned integer values, and the w-component as a 2 bit unsigned integer value.
For a list of additional functionality such as constructors and operators that are available
using XMUDEC4
when you are programming in C++, see XMUDEC4 Extensions.

Remarks
XMUDEC4
can be loaded into instances of XMVECTOR by using
XMLoadUDec4.
Instances of XMVECTOR
can be stored into an instance of XMUDEC4
with XMStoreUDec4.
