Anything that's been interpreted in an artistic form is a rendering — a song, a drawing, a theatrical performance.
On a more technical note, an architect's drawing or plan is known as a rendering. While we're still architect-related, the coat of stucco placed over the surface of a masonry wall can be a rendering as well. Rendering can also represent the giving of something, as in Gandhi's famous quote, that "We win justice quickest by rendering justice to the other party." Don't associate rendering with the verb rend — which means quite the opposite — "to break apart or destroy."
