GodotTD: Adapting a Lightweight Open-Source Game Engine for Immersive Tiled Displays

Abstract

The presentation of interactive 3D content on immersive tiled dis- plays requires specialized software solutions. Multiple challenges need to be overcome such as synchronization of a multitude of distributed clients, display calibration and integration of tracking de- vices. Previous software solutions are mostly built on top of open source scene graph libraries or by utilizing commercial game engines like Unity and Unreal. This contribution presents GodotTD, an adaption of the multi-platform Godot game engine for tiled dis- plays. The Godot engine is open source, very lightweight in terms of resource demands while offering modern, appealing visuals. Although the development of GodotTD is an ongoing effort, it has reached a level of maturity where it is regularly being used in a variety of scientific and academic applications.
