Question

由于JavaFX 8中的新功能，可以将3D对象与2D UI控件结合使用。

我将这些文档用作手册：JavaFX Tutorial，Exploring JavaFX 3D。

所以，我制作了这段代码：

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() {
        Box box = new Box(200,200,200);


        axisGroup.getChildren().addAll(box);
        world.getChildren().addAll(axisGroup);
    }

    private void handleMouse(Scene scene, final Node root) {

                double modifier = 1.0;

                }
            }

    }

    public static void main(String[] args) {
        launch(args);
    }
}

但结果并不是我的预期。我想让Pane用于3D对象上方的UI控件，但我得到的是：

我做错了什么？

Answer 1

根据我所理解的（有限的）测试，我有两种选择：

为子场景设置摄像机，并将该子场景添加到根目录。您将只使用一台相机。你的世界必须是一个独立的团体，飞行/旋转摄像机视图必须通过改造世界组来实现。
使用JavaFX jira提交错误报告。

我没有成功使用单独的相机作为子场景相机。没有应用于相机或子场景本身的变换曾经从默认位置旋转子场景，类似于屏幕截图中的位置。在这一点上，Oracle没有发布任何子场景文档，我们只能等到它们变得干净并填补空白。在此之前，我们可以考虑在JavaFX 3D中支持子网络支持。

Answer 2

问题在于：

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

您只能在Scene（或SubScene）中设置一个摄像头。您需要在SubScene中设置第二个Camera。尝试这样的事情：

@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);
}

Answer 3

这是解决方案

@using (Html.BeginForm("Save","Home"))
{   
    <div class="form-horizontal">

        @if (TempData["CallFrom"] != null && Convert.ToString(TempData["CallFrom"]) == "SenditNow")
        {
            <h1>SenditNow</h1>
            <input type="text" value="NameOfCustomer" />
            <input type="text" value="Address" />
        }

        else
        {
            <h1>SafeForLater</h1>
            <input type="text" value="NameOfCustomer" />
            <input type="text" value="Address" />
        }
        <hr />
        <button class="formular-button-submit" type="submit" name="submit" id="SenditNow" value="SenditNow">Send it now!</button>
        <button class="formular-button-submit" type="submit" name="submit" id="SafeForLater" value="SafeForLater">Safe it for later!</button>
    </div>
}
