XMSHORT4::XMSHORT4(constfloat*) function (directxpackedvector.h)

  • Article

Initializes a new instance of XMSHORT4 from a four element float array argument.

This constructor initializes a new instance of XMSHORT4 from a four element float array argument.

Note  This constructor is only available under C++.

Syntax

void XMSHORT4(
  const float *pArray
) noexcept;

Parameters

pArray

Four element float array containing the values used to initialize the four components of a new instance of XMSHORT4.

Return value

None

Remarks

The magnitude of each member of the pArray argument to the constructor will be clamped to the range supported by a 16-bit unsigned integer [-32767.0, 32767.0].

The following pseudocode demonstrates the operation of this constructor:

XMSHORT4 instance;

instance.x = (int16_t)min( max( pArray[0] -32767.0 ), 32767.0 );
instance.y = (int16_t)min( max( pArray[1] -32767.0 ), 32767.0 );
instance.z = (int16_t)min( max( pArray[2] -32767.0 ), 32767.0 );
instance.w = (int16_t)min( max( pArray[3] -32767.0 ), 32767.0 );
