XMU565::XMU565(float,float,float) function (directxpackedvector.h)
Initializes a new instance of XMU565 from three float arguments.
This constructor initializes a new instance of XMU565 from three
float arguments.
Syntax
void XMU565(
float _x,
float _y,
float _z
) noexcept;
Parameters
_x
Value of the x-coordinate of the vector, the x member of the new
XMU565 instance.
The magnitude of this argument will be clamped to a range of [0.0, 31.0].
_y
Value of the y-coordinate of the vector, the y member of the new
XMU565 instance.
The magnitude of this argument will be clamped to a range of [0.0, 63.0].
_z
Value of the z-coordinate of the vector, the z member of the new
XMU565 instance.
The magnitude of this argument will be clamped to a range of [0.0, 31.0].
Return value
None
Remarks
The following pseudocode demonstrates the operation of this constructor, which takes
advantage of the union of the three components of the XMU565 vector
with an instance of uint16_t in the definition of the structure:
XMU565 instance;
_x1=min( max( _x, 0.0 ), 31.0 );
_y1=min( max( _y, 0.0 ), 63.0 );
_z1=min( max( _z, 0.0 ), 31.0 );
instance.v= ((z & 0x1F) << 11) |
((y & 0x3F) << 5) |
((x & 0x1F));
