Provides utilities related to coordinates.
Structs
An aligned world tile coordinate aligns a world coordinate at a 4x4 tile raster within the world. The aligned coordinates is defined by the coordinates of the upper left tile in the 4x4 tile raster divided by 2 and rounding to the ceiling.
Within each tile there is a separate coordinate system. Usually this coordinate system is
within crate::coords::EXTENT. Therefore, x and y must be within the bounds of
crate::coords::EXTENT.
Represents the position of a node within a quad tree. The first u8 defines the ZoomLevel of the node.
The remaining bytes define which part (north west, south west, south east, north east) of each
subdivision of the quadtree is concerned.
Every tile has tile coordinates. These tile coordinates are also called Slippy map tilenames.
Defines a bounding box on a tiled map with a ZoomLevel and a padding.
Actual coordinates within the 3D world. The z value of the [WorldCoors] is not related to
the z value of the [WorldTileCoors]. In the 3D world all tiles are rendered at z values
which are determined only by the render engine and not by the zoom level.
Every tile has tile coordinates. Every tile coordinate can be mapped to a coordinate within the world. This provides the freedom to map from TMS to Slippy_map_tilenames.
Zoom is an exponential scale that defines the zoom of the camera on the map.
We can derive the ZoomLevel from Zoom by using the [crate::coords::ZOOM_BOUNDS].
