Hi,
Searching forum i've found such topic
http://forum.openscenegraph.org/viewtopic.php?t=5758, which is quite similar to
my problem, however does not solved my issue. I'm trying to write functionality
to remove node with all subnodes, but cannot get it to work. Assign NULL to
shared pointer (
Hi Robert,
The OSG automatically reference counts Nodes and other objects in the scene
graph. If you want to remove Nodes or other objects from the scene graph
you need to call the appropriate methods to removing them. If you want to
remove a child from a group then you simply call group->remove
Hi,
Ok, i was mislead by previous thread and setting NULL to ref_ptr. So, i'm using
removeChild, as it should be and got crash. I'm doing this in such way:
Code:
osg::ref_ptr < osg::Geode > geode = new osg::Geode; // on start
osg::Geode* g = geode.get(); // store pointer to my geode somewhere
Hi Robert
Your crash is down to retaining a c pointer to an object that has been
deleted. This dangling pointer issue is exactly why smart pointers are used
in modern C++ application.
Lots has been written about ref_ptr usage here over the years, as well as
docs and osg books that discuss it. So
