Shayne,
In my application, a global buffer is used to input data to osg thread from
other thread.
I used the method as same as Todd told you. "setMatrix()" is used to update
the matrix of that MatrixTransform node.
...
osg::ref_ptr<osg::group> root;
osg::ref_ptr<osg::MatrixTransform> MotionMatrix;
osg::ref_ptr<osg::node> MotionModelFile; //your motion
model
...
root->addchild(MotionMatrix);
MotionMatrix->addchild(MotionModelFile);
...
while((!Viewer.done)
{
...
if(Update is
Needed) //position
is changed or other
MotionMatrix->->setMatrix(osg::Matrix::translate(Pos)); //your
position data
...
Viewer.frame();
...
}
