![]() ![]() I've written an example program that illustrates the issue, set up very similarly to the FXyz sample code but I've created an extra SubScene object to hold the 2D and 3D SubScene objects in order to plant them into a larger application window with slider controls. Connect to the pods SSH service using an SSH client. Alternatively, you can use a tool like kubectl port-forward to forward traffic from a local port to the pods SSH port. This can be done by creating a Kubernetes Service object that exposes the pods SSH port (usually port 22) to the cluster. The Label objects need to have their positions updated as the 3D scene in modified, which I've done but when I print out the coordinates returned by the Node.localToScene method, they're much too large to be within the application scene, and so the labels are never visible in the scene. Expose the pods SSH service to the network. I've taken example code from the FXyz FloatingLabels example here: But this doesn't seem to work for my case. I've seen similar questions to mine on this subject, and they all point to using the Node.localToScene method on the node to be labelled in the 3D space.
