Function bitwise::word::morton::decode_2d
[−]
[src]
pub fn decode_2d<T: Word>(v: T) -> (T, T)
Decodes an interleaved Morton index for a Z-Curve into two-dimensional coordinates.
Using _.i
to denote the i
-th bit in a word, this function decodes
the following bit pattern of v
:
v = |y.N|x.N|...|y.1|x.1|y.0|x.0|
where N == T::bit_size() / 2
,
into the coordinates x
and y
with the following bit pattern:
x: |...0|x.N|...|x.1|x.0|
y: |...0|y.N|...|y.1|y.0|
Example
use bitwise::word::morton; let x = 0b0000_1010u8; let y = 0b0000_0011u8; let r = 0b01_00_11_10u8; assert_eq!(morton::decode_2d(r), (x, y));
