Re: [Gnu3dkit-dev] 3D file formats

[Matt Brandt]

I guess I would lean toward something halfway between a bunch of 
reader/writer classes and a database. It seems to me like the scene 
graph really is the database, but we might need to add a little bit of 
information to make things more explicit. Named nodes would be the main 
thing I can think of, so that a scene object could be reused without a 
great deal of work. If we try to get into the idea of merging nodes I 
think we can end up breaking things inadvertently. In some scenes an 
object might seem like a static object most of the time and just need 
to be dynamic for one thing. Only the creator will know for sure. 
Optimizations like that can be left up to the program that creates the 
scene (or the person).

I lean toward doing a protocol for a reader/writer and then 
implementing the file formats separately without an intermediate format.
