Modeling a 2-Piece Flower Pot in GeoGebra Augmented Reality

In this screencast, we model a 2-piece flower pot in GeoGebra Augmented Reality. [br][br]Notice how the the domain restrictions for both surface equations help create this model. [br][b][br]What would these surfaces look like WITHOUT the domain restrictions set in place here? [/b]
Quick Demo
