Based on the comments in the list I think it is better to keep the type that was originally provided as a reference, take the address of it, and store that in a ref_ptr.
Possibly the problem was never compiler related rather OSG related; I'm using 3.5.x and it appears that there are better built in type conversions compared to the target version of 3.2 that we are currently using.
Change to use pointers rather than osg::ref_ptr<osg::Group> - based on http://andesengineering.com/OSG_ProducerArticles/RefPointers/RefPointers I think that it is not possible that the scenegraph can be modified between the visitor and the modify, provided that the methods are called after each other like this:
ReplaceStaticTextureVisitor visitor(name, new_texture);
branch->accept(visitor);
visitor.modify_groups();
return visitor.getPlacements();
The visitor would modify the scenegraph during the traversal by inserting groups; this is not valid when using vectors, and MSVC2015 debug RTL throws an exception when this happens.
The fix is to simply make a list of the textures that need to be modified and modify once the scenegraph traversal has finished.
- Add option 'capture-events' to canvas aircraft and scenery
placements to allow events being forwarded to the respective
canvas.
- Clean up and restructure parts of the mouse event/picking
handling to support forwarding events to canvasses.
