XMDECN4::XMDECN4(uint32_t) function (directxpackedvector.h)
Initializes a new instance of XMDECN4 from a uint32_t variable containing
component data in a packed format.
This constructor initializes a new instance of XMDECN4 from a
uint32_t variable containing component data in a packed format.
Note This constructor is only available under C++.
Syntax
void XMDECN4(
uint32_t Packed
) noexcept;
Parameters
Packed
The values of four vector components in a packed format.
Return value
None
Remarks
The values defining the four components of the new instance of XMDECN4 are
not normalized and are stored in the argument Packed as follows:
-
The first 10 bits (bits 0-9) of Packed assigned, as an integer, to
the x member of the instance of
XMDECN4constructed. -
The second 10 bits (bits 10-19) of Packed assigned, as an integer, to
the y member of the instance of
XMDECN4constructed. -
The third 10 bits (bits 20-29) of Packed assigned, as an integer, to
the z member of the instance of
XMDECN4constructed. -
The last 2 bits (bits 30-31) of Packed assigned, as an integer, to
the w member of the instance of
XMDECN4constructed.
