XMXDEC4 union
A 4D vector with x-,y-, and z- components represented as 10 bit signed integer values, and the w-component as a 2 bit unsigned integer value.
Syntax
union XMXDEC4 { union { struct { int32_t x; int32_t y; int32_t z; uint32_t w; }; uint32_t v; }; };
Members
- x
-
Signed integer value in the range [-511, 511] describing the x-coordinate of the vector.
- y
-
Signed integer value in the range [-511, 511] describing the y-coordinate of the vector.
- z
-
Signed integer value in the range [-511, 511] describing the z-coordinate of the vector.
- w
-
Unsigned integer value in the range [0, 3] describing the w-coordinate of the vector.
- v
-
Unsigned 32-bit integer representing the 4D vector.
Remarks
XMXDEC4 can be loaded into instances of XMVECTOR by using
XMLoadXDec4.
Instances of XMVECTOR can be stored into an instance of XMXDEC4 with XMStoreXDec4.
