Hi,
I want to pick one node using mouse. then the node deleted. but I failed. I
don't know why. the nodepick.h attached.
the osg::Node* pNode can be picked. and it can be changed to red.
but the following mViewer->getSceneData()->asGroup()->removeChild(pNode);

I also used m_Rt->remov
Hi,
I am studying how to delete node from root recentlly.

// float bias = ssm->getBias();
//
Hi,

all these osg::MatrixTransform were added to one group.
But the program runs very very slow.
In fact I create the same scene using
5 matches
