[WF-Protocols] Exchange/Native format

[Matze Braun]

I think one of the first things we should discuss is wether we 
should focus on a model exchange format or something which can be used by 
engines. IMO we should focus on an exchange format. I think having a very 
customisable and extensible format as main model format will result in 
performance problems:
	-The data is probably not in the order that the engine would need 
	 it. So jumping around in the file or using big memory caches will 
	 be the result.
	-The model might contain features that aren't supported by the 
	 engine directly (even simple things like polygons vs. triangles 
	 or double sided faces, UV coordinates attached with vertices or 
	 faces). These features need to be converted into engine format 
	 while loading which takes time.
	-You can't control the format in which the things are saved (with 
	 format I mean the problems like above), so some models might load 
	 fast others slow.

So IMO we should focus on an exchange format, because that is what artists
need. The engines can provide converter apps for the exchange format then.
