A level of detail node may hold in a bounding volume hierarchy, an object identifier, a distance at which a transition occurs between levels of detail and a bias. When a level of detail node is encountered in the hierarchy, the distance value may be used to select a level of detail. Sometimes a different level of detail is loaded because the preferred level is not available. The different level may be marked in a register. Then for a subsequence frame, the correct level is used. A node bias may be used to override the level of detail selection is some cases.
