I want to make an app that uses a three dimensional image of an object. Is there an software to help do such a thing or other public domain graphics of three dimensional objects in some sort of free repository?
I suppose a 'model' is another word to use, basically I want to have an app that shows a 3d image of a real world object that can be viewed from multiple angles - however the user won't need to interact with the 3d image, simply be able to view the object as it rotates automatically.
