We have emphasized that the isometric projection gives a 2.5D- or 3D-like feeling. So what are the differences between a full 3D camera view and isometric view? It is often a good option to demonstrate isometric projection with a perfect cube.
In 3D perspective projection, objects have vanishing points and while they are moving, the lines and shapes keep changing.
In isometric projection, objects do not have vanishing points. The shapes and lines of the objects do not change while they are moving.
The world map is divided into a set of small pieces in games with tile-based geometry. These pieces are called tiles. The tiles align adjacent to each other into a grid. Each tile represents a graphic asset and the whole tile set forms the virtual world. When the tiles are rectangles, they align on traditional X/Y coordination.
The geometry of an isometric ground can be mapped to the traditional tile-based geometry. It is actually a rotated...
