## Detailed Description

Provides a way of enabling child entities based on distance or screen size.

This component is assigned to an entity. When the entity changes distance relative to the camera, the QLevelOfDetailSwitch will disable all the child entities except the one matching index Qt3DRender::QLevelOfDetailSwitch::currentIndex.
