XMVECTORU8 Data Type
An opaque, portable type to support the use of C/C++ initializer syntax to load uint8_t values into an instance of XMVECTOR type.
typedef XMVECTORU8 vectoru8;
Remarks
For a list of additional functionality, such as constructors and operators, available using XMVECTORU8 when programming in C++, see XMVECTORU8 Extensions.
The XMVECTORF32, XMVECTORU32, XMVECTORI32, and XMVECTORU8 structures are provided as a mechanism for creating XMVECTOR from different constant data types (floating point, unsigned integer, integer, and byte) using initializers.
This is necessary to support XMVECTOR, as it does not itself support initializers, for portability and optimization reasons.
For example:
XMVECTOR data;
XMVECTORU8 byteVector = { (uint8_t) 1,(uint8_t) 16,(uint8_t)101,(uint8_t) 62,
(uint8_t) 4,(uint8_t) 0,(uint8_t) 2,(uint8_t) 99,
(uint8_t) 9,(uint8_t) 18,(uint8_t) 0,(uint8_t) 0,
(uint8_t)100,(uint8_t) 51,(uint8_t) 23,(uint8_t)117};
data = floatingVector;
