Re: [osg-users] Annoying version verification of models

2009-10-22 Thread Robert Osfield
Hi Alejandro,

Unfortunately the .ive plugin isn't forwards compatible - it can't
accommodate changes to the file format that will be made in the
future, so if the format has even been slightly amended in a new
version of the OSG, trying to use that file format in older version of
the OSG won't be successful.   The .ive plugin is however backwards
compatible.

Changing the .ive plugin to be forwards compatible will require
significant changes to the loaders and the implementation.

If you need a more flexible exchange format then the .osg ascii format
will be better as it can accommodate elements that it doesn't
recognize by simply reading past the end of them.

Robert.

 Hello,

 I generated a terrain model in my laptop at home, then I did bring the

 $ osgviewer  isolineas/ene_cont.ive
 DataInputStream::DataInputStream(): The version found in the file is
 newer than this library can handle.
 osgviewer: No data loaded

 This is silly, the OSG version in my laptop is as much one week newer
 than the one I have here. VPB is exactly the same version in both
 machines. Is there a way to make osgdb less picky?
