Syntax


XMVECTOR XMLoadUDecN4(
  [in]  const XMUDECN4 *pSource
);

Parameters

pSource [in]

Address of the XMUDECN4 structure to load.

Return value

Returns an XMVECTOR loaded with the data from the pSource parameter.

Remarks

The following pseudocode demonstrates the operation of the function.


XMVECTOR vectorOut;

uint32_t Element;

Element = pSource->v & 0x3FF;
vectorOut.x = (float)Element / 1023.f;
Element = (pSource->v >> 10) & 0x3FF;
vectorOut.y = (float)Element / 1023.f;
Element = (pSource->v >> 20) & 0x3FF;
vectorOut.z = (float)Element / 1023.f;
vectorOut.w = (float)(pSource->v >> 30) / 3.f;

return vectorOut;
