Disclaimer: I’m trying to learn proper OO programming/design, so I’m pretty new to this stuff.
I guess this is a general design patterns question, but I’ll base my example on a game engine or something that renders objects to the display.
Consider the following:

How can this sort of separation between physical objects (e.g., cubes, spheres, etc.) and the rendering mechanism be achieved in an extensible manner?
This design is not set in stone, and perhaps I’ve got something wrong from the start. I’m just curious as to how a problem like this is solved in real world code.
That would be the Adapter pattern, or it could be implemented as a Strategy pattern.
