Sorry, I don't understand your question. What do you mean by 'Object' 
here?

A RIB file is a serialised byte stream which uses the RenderMan 
Interface. Thus if we are going to use this interface as discussed 
earlier then we will be able to create RIB files from 3DKit scene 
graphs. But maybe this is not what you want to know...?
