Therefore the modeller needs to provide multiple resolution LOD with different polygon-density.
The algorithm needs enough different resolution LOD to be effective. In Arma 3 the number of the resolution LOD has no impact and there is no way to specify which LOD is to be used at which range.
view-distance, number of objects, video quality, CPU utilization, etc.).
The switching of different resolution LOD happens automatically, based on various factors / in-game conditions (e.g. Without the resolution LOD technique, the games would be unplayable due to bad performance. This is done to prevent excessive demand of computing ressources. In Open-World 3D Games (including all Arma Titles) it is standard practice to swap out high-resolution Models with medium- or low-resolution models at far distance from the observer. There should always be more than 1 resolution LOD (unless it is a low poly object). Resolution LOD are those LOD that are visible in the game to the player from the outside view.
