[osg-users] Re: Export GLTF from OSG?
Hi Robert, The animations are reading live data and rendering them - so it's not a simple format, but can be represented by gltf well: the mesh models are static, but can appear and disappear and can have arbitrary transformations applied to them. My vision is an exporter that exports each unique Geode exactly once, and everything else in the scenegraph exported each frame. That would work well for a wide range of OSG-based applications, it seems, and GLTF seems well-suited for this.

[osg-users] Re: osgQt::GLWidget Scroll Bug
Hi Scott,
I don't know where the issue lies, but most likely it's in the windowing
integration side rather than the core OSG as it doesn't look like you'll be
relying on any of the OSG's native windowing/event handling. There might
be an issue with osgQt, but I'm not the author of maintainer for it so will
have to defer to others on this. Or it could be an issue with osgEarth.
The best I can suggest is that you build the OSG, osgEarth, osgQt and your
application in debug mode, then step through the code in a debugger to see
where the control flow passes when the wheelEvent happens.
Cheers,
Robert.
