XMFLOAT3PK::XMFLOAT3PK(uint32_t) function (directxpackedvector.h)
Initializes a new instance of XMFLOAT3PK from a uint32_t variable containing component data in a packed format.
This constructor initializes a new instance of XMFLOAT3PK from a
uint32_t variable containing component data in a packed format.
Note This constructor is only available under C++.
Syntax
void XMFLOAT3PK(
uint32_t Packed
) noexcept;
Parameters
Packed
The values of three vector components in a packed format.
Return value
None
Remarks
The values of the three components of the new instance of XMFLOAT3PK are stored
in the argument Packed with the z component (as a reduced precision
floating point number) in the most significant bits, and the x component is stored in the
least significant bits:
(Z10Y11X11): [32] ZZZZZzzz zzYYYYYy yyyyXXX XXxxxxxx [0]
Or in detail:
- Bits 0-5 of v are the 6 bit mantissa of the x component's floating point value: the xm member of new instance of the structure.
- Bits 6-10 of v are the 5 bit exponent of the x component's floating point value the xe member of new instance of the structure.
- Bits 11-16 of v are the 6-bit mantissa of the y component's floating point value: the ym member of new instance of the structure.
- Bits 17-21 of v are the 5 bit exponent of the y component's floating point value: the ye member of new instance of the structure.
- Bits 22-26 of v are the 5 bit mantissa of the z component's floating point value: the zm member of new instance of the structure.
- Bits 27-31 of v are the 5 bit exponent of the z component's floating point value: the ze member of new instance of the structure.
