Are there definitive, unambiguous terms for hexagon tile orientations? I have been working on a tile map editor and plan to support two orientations for hexagons. I have seen various terms used, but these all seem ambiguous to me. Horizontal, Vertical (ambiguous does this mean they line up horizontally, or stack horizontally?) Flat, Pointed (ambiguous Are they flat on the sides or top and bottom?) I would like to find unambiguous terms for the following two orientations for hexagons ideally, these would be definitive and succinct (I could refer to these as "Flat on Top" and "Pointed on Top" but would prefer something more technical and authoritative). Edit I was holding out for something more technical, but it's hard to argue with Amit. For me, "pointed" sounds more formal than "pointy," so I am going to use the following (a decision reinforced by DMGregory's answer) Flat top and Pointed Top.
