XMSHORTN4 structure
A 4D vector for storing signed, normalized values as signed 16-bit integers, (type int16_t).
For a list of additional functionality such as constructors and operators that are available
using XMSHORTN4 when you are programming in C++, see XMSHORTN4 Extensions.
Syntax
struct XMSHORTN4 {
int16_t x;
int16_t y;
int16_t z;
int16_t w;
};
Members
- x
-
Signed 16-bit integer in the range [-32767, 32767] describing the x-coordinate of the vector.
- y
-
Signed 16-bit integer in the range [-32767, 32767] describing the y-coordinate of the vector.
- z
-
Signed 16-bit integer in the range [-32767, 32767] describing the z-coordinate of the vector.
- w
-
Signed 16-bit integer in the range [-32767, 32767] describing the w-coordinate of the vector.
Remarks
Those XMSHORTN4 constructors using floating point arguments require normalized input,
which must be in the range of [-1.0.-1.0]. During instantiation, these data are
multiplied by 32767.0f, results are rounded, and then
assigned to the appropriate members of XMSHORTN4.
XMSHORTN4 can be used to load instances of XMVECTOR from
normalized values, by using XMLoadShortN4, which divides each
component 32767.0f, rounds the result, and then assigns the components to an
XMVECTOR instance.
XMVECTOR instances containing normalized values can be stored into XMSHORTN4
using XMStoreShortN4, which multiplies each component by 32767.0f,
rounding the result, before assigning the values to the appropriate XMSHORTN4 members.
