XMLoadU555 function (directxpackedvector.h)
Loads an XMU555 into an XMVECTOR.
Syntax
XMVECTOR XM_CALLCONV XMLoadU555(
[in] const XMU555 *pSource
) noexcept;
Parameters
[in] pSource
Address of the XMU555 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;
vectorOut.x = (float)pSource->x;
vectorOut.y = (float)pSource->y;
vectorOut.z = (float)pSource->z;
vectorOut.w = (float)pSource->w;
return vectorOut;
Note these are not normalized values. To convert to the RGBA 5/5/5/1 format,
you must scale the resulting vector by (1.f/31.f, 1.f/31.f, 1.f/31.f, 1.f).
Also, you will probably need to swizzle the standard .x = RED, .y = GREEN, .z =
BLUE, .w = ALPHA color vector's .x and .z value since the GPU format is BGR (not RGB).
