XMU555::XMU555(uint8_t,uint8_t,uint8_t,bool) function (directxpackedvector.h)
Initializes a new instance of XMU555 from three int8_t and one bool arguments.
This constructor initializes a new instance of XMU555 from three int8_t (specifying x-, y-, and z-components) and one bool (specifying a w-component) arguments.
Syntax
void XMU555(
uint8_t _x,
uint8_t _y,
uint8_t _z,
bool _w
) noexcept;
Parameters
_x
Value of the x-coordinate of the vector, the x member of the new XMU555 instance.
The magnitude of this argument will be clamped to a range of [0, 31].
_y
Value of the y-coordinate of the vector, the y member of the new XMU555 instance.
The magnitude of this argument will be clamped to a range of [0, 31].
_z
Value of the z-coordinate of the vector, the z member of the new XMU555 instance.
The magnitude of this argument will be clamped to a range of [0, 31].
_w
Value of the w-coordinate of the vector, the <wdcml:mark type="member">w</wdcml:mark> member of the new XMU555 instance.
The magnitude of this argument will be clamped to a range of [0, 1].
Return value
None
Remarks
The following pseudocode demonstrates the operation of this constructor, which takes advantage of the union of the four components of the XMU555 vector with an instance of uint16_t in the definition of the structure:
XMU555 instance;
_x1=min( max( _x, 0 ), 31 );
_y1=min( max( _y, 0 ), 31 );
_z1=min( max( _z, 0 ), 31 );
_w1=min( max( _w, 0 ), 1 );
instance.v = (((uint16_t)_w1) ? 0x8000 : 0) |
(((uint16_t)_z1 & 0x1F) << 10) |
(((uint16_t)_y1 & 0x1F) << 5) |
(((uint16_t)_x1 & 0x1F));
