Talk:Hexagonal sampling

Error
I don't think that the following is correct:


 * In hexagonal sampling, the V matrix assumes the following general form:-
 * :$$ V_{hex}=\begin{bmatrix} T1 & T2 \\ T1 & -T2 \end{bmatrix}$$

Using only one direction given by this matrix, i.e. multiplying by (1,0), (2,0), (3,0) ... we would move the sample positions along a 45 degree line. This clearly isn't the case when comparing to the related figure for the hexagonal sampling grid.

The correct form of the matrix is


 * :$$ V_{hex}=\begin{bmatrix} T1 & T1 \\ -T2 & T2 \end{bmatrix}$$ — Preceding unsigned comment added by 223.239.24.157 (talk) 15:38, 15 December 2021 (UTC)

clarity
The lead section does not mention hexagonal sampling. I really have no idea what it means. Setreset (talk) 13:40, 22 March 2021 (UTC)
