As nouns the difference between mockup and diorama
is that mockup is a prototype, usually low-fidelity, such as paper illustrations, screenshots, or simple configurations of screens with limited interaction while diorama is a three-dimensional display of a scenery, often having a painted background in front of which models are arranged, e.g. in a museum where stuffed animals are presented against a painted landscape.
