Hi,
I'd like to change the Position of an Object in my Scene after picking
it by mouse picking.
I already have a ref_ptr, call it m_Node, pointing to the Object I want
to move, but I don't know how to apply the changes correctly. I don't
want to insert another MatrixTransform, I'd like to modify the original
one to translate the Object to the new position.
something like this?
osg::MatrixTransform* mat = dynamic_cast<osg::MatrixTransform*>(m_node);
if (mat) {
mat->setMatrix( mat->getMatrix() *
osg::Matrix::translate(x,y,z) );
}
Something similar to this code should work,
HTH,
Stephan
