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.
