JavaFX 8 の新機能により、3D オブジェクトを 2D UI コントロールと組み合わせることが可能になりました。

このドキュメントをマニュアルとして使用しました: JavaFX Tutorial、Exploring JavaFX 3D。

だから、私はこのコードを作りました：

    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 mouseDeltaY;

しかし、結果は私が期待したものではありません。Pane3D オブジェクトの上の UI コントロールが欲しかったのですが、得られるのは次のとおりです。

私は何を間違っていますか？

問題はここにあります：

    scene.setCamera(subSceneCamera);
    scene.setCamera(camera);

Scene (または SubScene) に設定できるカメラは 1 つだけです。SubScene で 2 つ目のカメラを設定する必要があります。次のようなことを試してください：

@Override
public void start(Stage primaryStage) throws Exception{
    ...
    primaryStage.show();
    scene.setCamera(camera);
}
private void buildScene() {
    ...
    subScene.setLayoutX(100);
    subScene.setLayoutY(100);
    subScene.setCamera(subSceneCamera);
    root.getChildren().addAll(subScene);
}
