I think there is no more original art or ideas. Everything is derivative or a slight  extensiopn of something that has gone before. When some tries to be original now we get the nonsense of such as Pollock, or an unmade bed pretending to be art.
 
For instance: The computer consoles in the new star treck movie are echos od  real computer screens and control systems. The pointy ears in Avatar could be Mr Spock's ears. Yhe cosoles in Avatar coulld be real models of Homer Simpson's console Harry potter uses wizadry but there have been wizards since Merlin or before.

Building a 3D model from a 2D source cannot be accurate enough to be anything but derivative I think. Only if the actual texture from the movie etc is used to in a model should it be considered plagerism or breach of copyright.
