XMU565::XMU565(constuint8_t*) function (directxpackedvector.h)

Initializes a new instance of XMU565 from a three element int8_t array.

This constructor initializes a new instance of XMU565 from a three element int8_t array.

Syntax

void XMU565(
  const uint8_t *pArray
) noexcept;

Parameters

pArray

Three element character array containing the values used to initialize the x-, y- and z-components of a new instance of XMU565.

Return value

None

Remarks

Array elements and the _w argument are mapped to the vector components of a new instance of XMU565 as follows:

Arguments to the constructors will be clamped to the permitted range prior to assignment to the appropriate member of XMU565.

The following pseudocode demonstrates the operation of this constructor, which takes advantage of the union of the three components of the XMU565vector with an instance of uint16_t in the definition of the structure:

XMU565 instance;
_x1=min( max( pArray[0], 0 ), 31);
_y1=min( max( pArray[1], 0 ), 63 );
_z1=min( max( pArray[2], 0 ), 31 );

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