In-game Mini-map Prototypes

Here I will try to collect the most popular/cool looking UI-mechanics used to represent the in-game mini-maps.
Feel free to contact me if you've got something to add!

Compass-like - markers' visibility is limited by the view radius.

Panorama like - markers are placed along the horizontal line,
visibility is controlled according to the view angle.

3D isometric mini-map, similar to #1, except for the map surface is slightly angled.
