These screen-shots show examples of the Ca3DE Graphical User Interface System, the "GuiSys".

• The GUI system is employed both for normal 2D GUIs like the main menu, the in-game console, the HUDs (head-up-displays) etc.,
• as well as for the 3D GUIs in the worlds, e.g. as control panels to open doors, call lifts, or for any other purpose the map designer desires.
