Re: [osg-users] Promoting Drawable from being subclassed from osg::Object to osg::Node

[Pjotr Svetachov]

I was trying to save a file to .ive format today but that failed with the message: "Unknown node in Group::write(), className()=Geometry"
So right now it looks like it's impossible to write to .ive files.
While osgt/osgb files work I looked at the code and noticed that the osg::Drawable does not have an osg::Node associate which means that node specific fields like _cullingActive and _nodeMask are not saved.

Cheers,
Pjotr

Hi Robert,

I made a small change to DataOutputStream.cpp which makes saving Geodes possible again. This is only half a fix as it only will save a Drawable that is part of a Geode. But this change does not require a version bump of the .ive format. I tried it with a few datasets we have here with the 3.2 stable branch and the trunk with this patch and there was no difference in the .ive files that were produced.

Cheers,
Pjotr
