Isometric tilemap games use an axonometric projection to give the impression of looking at the scenery from an angle, thus creating visual depth. Axonometric projection is the technical term for projecting a rotated three-dimensional object onto a two-dimensional plane. The image then becomes skewed but our minds still recognize it as a threedimensional object. In terms of tilemaps, if you take a look at Figure 11 2 you can see the concrete steps for creating an isometric projection of an orthogonal image. The square is first rotated by 45 degrees and then scaled down along its Y axis to give it its typical isometric diamond shape.

However, Figure 11 2 is just the theoretical approach to illustrate the projection of the isometric shape. You can t turn an orthogonal image into an isometric image by simply rotating and compressing it because the rotation would affect the image content. It would just look flat and very wrong, just like Figure 11 3.

Instead, consider the diamond shape created in Figure 11 2 as your drawing canvas of the floor. The simplest isometric tiles you can design are flat ground tiles. Just fill the diamond shape with a certain pattern and you get yourself usable isometric tiles. Figure 11 4 shows a number of flat-colored isometric tiles laid out next to each other, creating a ground floor pattern. Ground floor tiles are not impressive, and look very flat. Yet they are essential as the game world s background layer.

To add actual visual depth to an isometric tilemap, you need to have object tiles that extend beyond the diamond shape. The most commonly used approach is to draw three-dimensional objects as if they were viewed at a 45-degree angle, and draw them up and over the diamond shape, typically extending no more than one tile above. In the example in Figure 11 5 you can see this quite nicely by looking at the doorway. The door arch is drawn mostly over the isometric tile above the one the door s frame is standing on. This gives the door its visual depth.
Figure 11 5. Add depth by drawing objects up to twice as high as the diamond shape.
Isometric tilemaps allow object tiles to overlap one another because the tiles are drawn from back to front, which means that object tiles closer to the viewer will always be drawn over tiles behind them, adding to the feeling of depth. But this approach requires careful design of individual tiles and the tilemap itself, because too much overlap or overlapping the wrong tiles can quickly destroy the illusion of depth. As a good practice, try not to overlap object tiles that have wildly different shapes, but do use the same or similar color palette. In the case of Figure 11 5, for example, you would not want to place the crystal tile directly behind the doorway. The loss in contrast and merging outlines of these tiles could easily destroy the perception of depth. Likewise, while you can create isometric object tiles that span much higher than twice the tile height, it s very hard to create a convincing 3D look if objects appear very high because the player will only see a part of the tilemap. If you were building a huge castle whose walls span a dozen tiles high, and the player approached them from below, the walls could easily be mistaken for a large section of ground floor. You can even end up creating optical illusions like the drawings of M. C. Escher because the isometric tiles do not get smaller the further away from the screen they are. So there s always a fine line between what works and what doesn t when designing isometric tiles and tilemaps.
