XMBYTEN2 structure
A 2D vector for storing signed, normalized values as signed 8-bits (1 byte) integers.
For a list of additional functionality such as constructors and operators that are available using XMBYTEN2 when you
are programming in C++, see XMBYTEN2 Extensions.
Syntax
struct XMBYTEN2 {
int8_t x;
int8_t y;
};
Members
- x
-
Signed 8-bit integer value in the range [-127, 127] describing the x-coordinate of the vector.
- y
-
Signed 8-bit integer value in the range [-127, 127] describing the y-coordinate of the vector.
Remarks
Those XMBYTEN2 constructors using floating point arguments require normalized input, which must be in the range of
[0.0.-1.0]. During instantiation, this data is multiplied by 127.0f, results are rounded, and then assigned to the
appropriate members of XMBYTEN2.
XMBYTEN2 can be used to load instances of XMVECTOR from normalized values,
by using XMLoadByteN2, which divides each component 127.0f, rounds the result,
and then assigns the components to an XMVECTOR instance.
XMVECTOR instances containing normalized values can be stored into XMBYTEN2 using
XMStoreByteN2, which multiplies each component by 127.0f, rounding the result, before assigning
the values to the appropriate XMBYTEN2 members.
