XMU565::XMU565(uint8_t,uint8_t,uint8_t) function (directxpackedvector.h)

Initializes a new instance of XMU565 from three int8_t arguments.

This constructor initializes a new instance of <wdcml:xref rid="dxmath.xmu565" targtype="struct">XMU565 </wdcml:xref> from three int8_t arguments.

Syntax

void XMU565(
  uint8_t _x,
  uint8_t _y,
  uint8_t _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, 31].

_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, 63].

_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, 31].

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 ), 31 );
_y1=min( max( _y, 0 ), 63 );
_z1=min( max( _z, 0 ), 31 );

instance.v= ((z & 0x1F) << 11) |
            ((y & 0x3F) << 5) |
            ((x & 0x1F));
