Re: [osg-users] Develop a scalable binary file format for native OSG scenes?

Hi Robert, 2009/12/11 Robert Osfield robert.osfi...@gmail.com: I believe .osg would be the most appropriate extension, the header could declare which version of the format it is - whether it's binary, new ascii or old ascii.  We could possible have a .osgb for binary. It should be easy to

Hi Paul, If .osgb isn't yet used in anything public, and it's the most nature naming for a OSG native binary format then I believe we should forgo the first dibs on the file extension and adopt it for the native binary OSG format - what we want is clarity for the widest number of people.
