XMU555::XMU555(float,float,float,bool) function (directxpackedvector.h)
Initializes a new instance of XMU555 from three float and one
bool arguments.
This constructor initializes a new instance of XMU555 from three
float (specifying x-, y-, and z-components) and one bool (specifying
the w-component) arguments.
Syntax
void XMU555(
float _x,
float _y,
float _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, 31.0].
_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, 31.0].
_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, 31.0].
_w
Value of the w-coordinate of the vector, the w 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:
_x1=min( max( _x, 0.0 ), 31.0 );
_y1=min( max( _y, 0.0 ), 31.0 );
_z1=min( max( _z, 0.0 ), 31.0 );
_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)));
