Hi! I've been working on developping an imaging system and currently I use a square matrix (so I can simply display my image via imagec(MATRIX)). However I want to switch to hexagonal pixels for several reasons and displaying it seems to go from trivial to very difficult. I also realize that the question of pixel indicse arises but this question seems more tangible to me. If anyone has any help that would be greatly appreciated! Thanks!

Why do you want hexagonal pixels (maybe we can provide hints toward an alternative)

How many square monitor pixels do you want to use to display one hexagonal pixel?

I would recommend, for memory/math purposes keeping a square pixel and then writing a function to display them as hexagonal if that's all you need hexagonality for.

The reason why I want hexagonal pixels is for increased packing density. Also my imaging system (like all others) assumes uniformity throughout the pixel and in a square pixel the distance to a corner is sqrt(2)*the distance to the centre of a side. For a hexagonal pixel this reduces to 2/sqrt(3).

What my system currently does is it raster scans through a square portion of my sample (taking one pixel every step). If I simply shift over every other row to the left or right by a half step I acquire the pixels hexagonally, which is great. The only problem is now displaying them hexagonally seems to be difficult.
