Parenting consists of adding an additional parent layer transformation to a layer's transformation.
To understand this concept, we can use the example of getting on a train. Inside the train, you are free to move; but, you are also affected by the train’s movements. You are "parented" to the train and the same concept applies to layers.
The following terminology is established from this comparison:
- Parent layer(s)
- Child layer(s)
A Child layer can also be the Parent of another layer/other layers, creating a "transformation dependency tree". That's the way you define parenting in Autograph, in this separated module.
