I'm just starting to play around with openscenegraph and I'd like to know if
what I'm describing is possible. I have two nodes, which may both have paths.
I'd like to attach a line of sight camera between the two nodes in such a way
that the camera is aiming at node 1 from node 2 at all times. I'd then also
like to be able to zoom in and out relative to this line of sight.
I tried setting up a NodeTrackerManiulator, but that class seems to be able to
freely track just one node. However, I need something that can track a node
with camera movement constrained by another node. I tried something like the
following:
Code:
osg::ref_ptr<osgGA::NodeTrackerManipulator> manip2 = new
osgGA::NodeTrackerManipulator;
manip2->setTrackNode(plane);
manip2->setNode(sensor);
manip2->setTrackerMode(osgGA::NodeTrackerManipulator::NODE_CENTER);
addView(manip2.get());
but it seems to still freely track just the plane node.
Thanks in advance,
