Due to new features in JavaFX 8, it became possible to combine 3D objects with 2D UI controls.
I used this documents as manuals: JavaFX Tutorial, Exploring JavaFX 3D.
So, I made this code:
public class CastAnalytics extends Application {
final Group root = new Group();
final Group axisGroup = new Group();
final XForm world = new XForm();
final PerspectiveCamera camera = new PerspectiveCamera(true);
final PerspectiveCamera subSceneCamera = new PerspectiveCamera(false);
final XForm cameraXForm = new XForm();
final XForm cameraXForm2 = new XForm();
final XForm cameraXForm3 = new XForm();
final double cameraDistance = 450;
final XForm moleculeGroup = new XForm();
private Timeline timeline;
boolean timelinePlaying = false;
double CONTROL_MULTIPLIER = 0.1;
double SHIFT_MULTIPLIER = 0.1;
double ALT_MULTIPLIER = 0.5;
double mousePosX;
double mousePosY;
double mouseOldX;
double mouseOldY;
double mouseDeltaX;
double mouseDeltaY;
@Override
public void start(Stage primaryStage) throws Exception{
buildScene();
buildCamera();
buildAxes();
Scene scene = new Scene(root, 1024, 768, true);
scene.setFill(Color.GREY);
handleKeyboard(scene, world);
handleMouse(scene, world);
primaryStage.setTitle("Sample Application");
primaryStage.setScene(scene);
primaryStage.show();
scene.setCamera(subSceneCamera);
scene.setCamera(camera);
}
private void buildScene() {
root.getChildren().add(world);
Label label = new Label("123");
HBox hBox = new HBox();
hBox.getChildren().add(label);
SubScene subScene = new SubScene(hBox, 200, 200);
subScene.setLayoutX(100);
subScene.setLayoutY(100);
root.getChildren().addAll(subScene);
}
private void buildCamera() {
root.getChildren().addAll(cameraXForm);
cameraXForm.getChildren().add(cameraXForm2);
cameraXForm2.getChildren().add(cameraXForm3);
cameraXForm3.getChildren().add(camera);
cameraXForm3.setRotateZ(180.0);
camera.setNearClip(0.1);
camera.setFarClip(10000.0);
camera.setTranslateZ(-cameraDistance);
cameraXForm.ry.setAngle(320.0);
cameraXForm.rx.setAngle(40);
}
private void buildAxes() {

axisGroup.getChildren().addAll(box);
world.getChildren().addAll(axisGroup);
}
private void handleMouse(Scene scene, final Node root) {
scene.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override public void handle(MouseEvent me) {

mouseOldY = me.getSceneY();
}
});
scene.setOnMouseDragged(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent me) {
mouseOldX = mousePosX;
mouseOldY = mousePosY;
mousePosX = me.getSceneX();
mousePosY = me.getSceneY();
mouseDeltaX = (mousePosX - mouseOldX);
mouseDeltaY = (mousePosY - mouseOldY);
double modifier = 1.0;
double modifierFactor = 0.1;
if (me.isControlDown()) {
modifier = 0.1;
}
if (me.isShiftDown()) {
modifier = 10.0;
}
if (me.isPrimaryButtonDown()) {
cameraXForm.ry.setAngle(cameraXForm.ry.getAngle() - mouseDeltaX * modifierFactor * modifier * 2.0); // +
cameraXForm.rx.setAngle(cameraXForm.rx.getAngle() + mouseDeltaY * modifierFactor * modifier * 2.0); // -

}
public static void main(String[] args) {
launch(args);
}
}
But te result isn't that what I expected. I wanted to have Pane for UI controls above the 3D object, but what I get is this:
What am I doing wrong?

From what I understand from the (limited) tests I have done, there are two options:
Set a camera for a sub-scene and add that sub-scene to the root. You will be using only one camera. Your world will have to be a separate group and flying/pivoting camera view will have to be accomplished by transforming the world group.
File a bug report with JavaFX jira.
I was not successful using a separate camera as a sub-scene camera. No transforms applied to the camera or a sub-scene itself ever rotated a sub-scene from the default position similar to the one in your screenshot. At this point with Oracle not releasing any sub-scene documentation, we can only wait till they come clean and fill the gaps. Until then we can consider subscene support in JavaFX 3D broken.
