In my cottage example, I have factory classes that create doors and windows and a factory class that creates the entire cottage. Configure the factory doorfactory. Tell the factory to build a door doorfactory. I set the colors for the door and then tell the factory to create it. Because this is utilizing my scene graph system where everything has reference counters associated with it, I can delete the class when I'm done.
Factory classes are a common software engineering tool.
The user utilizes tools to shape the material such that the material is radially symmetrical. I want you to create a class that will create graphical objects based on a template. You see the object that has been built from the template. Each point consists of a 2D value. The first value is the Y dimension and tells how high we are up the object.
