What is Parent?
Parents are an important concept in 3D visualization. It refers to the relationship between a parent object and its child objects. The parent object is the one that contains the child objects. The child objects are the ones that are contained within the parent object.
The parent object controls the position, orientation, and size of the child objects. This means that if you move, rotate, or scale the parent object, the child objects will follow along. You can think of the parent object as the “master” and the child objects as the “slaves.”
