<brief_description>
Provides discrete level of detail.
</brief_description>
<description>
Automatically hides and shows [Spatial] children depending on the distance from the closest [Camera] to the [LOD] node. Child nodes that don't inherit from [Spatial] are ignored by the LOD system.
Children are shown in order with the first children shown when closest to the [Camera], and the latter children shown when further away.
The threshold distances for changes are determined by [member Spatial.lod_range].
For example, a first child with a range of [code]2[/code] will be shown from distance 0 to 2. A second child with a range of [code]5[/code] will be shown from distance 2 to 7, etc.

<member name="hysteresis" type="float" setter="set_hysteresis" getter="get_hysteresis" default="1.0">
To prevent flickering at borders, a hysteresis distance will be added to threshold distances when the object is moving away from the [Camera].
</member>
<member name="lod_priority" type="int" setter="set_lod_priority" getter="get_lod_priority" default="0">
Determines the rate at which level of detail will be updated.
Higher priorities will update faster, but use more CPU.
