) noexcept;

Parameters

[in] pSource

Address of the XMBYTEN4 structure to load.

Return value

Remarks

The following pseudocode demonstrates the operation of the function.

XMVECTOR vectorOut;

vectorOut.x = (float)pSource->x / 127.0f;
vectorOut.y = (float)pSource->y / 127.0f;
vectorOut.z = (float)pSource->z / 127.0f;
vectorOut.w = (float)pSource->w / 127.0f;

return vectorOut;

Note that both -127 and -128 map to -1.f.
