从Java8開始，在JavaFX中便添加了3D部分的内容，包含Camera，Material，Light，Shape3D等基础内容。

当然，JavaFX 3D应该是OpenJFX里眼下正在补充和完好的一个模块，非常多地方还不尽如人意，所以该演示样例仅供參考。另外，OpenJFX眼下已经有人通过RovoVM执行在Android和IOS的设备上了。只是，个人觉得这个仅仅是小打小闹，还远远不能进入实际运用其中。

以下是JavaFX 3D演示样例，我会逐一解释:

import javafx.application.Application;
import javafx.application.Platform;
import javafx.scene.Group;
import javafx.scene.Parent;
import javafx.scene.PerspectiveCamera;
import javafx.scene.Scene;
import javafx.scene.SceneAntialiasing;
import javafx.scene.SubScene;
import javafx.scene.paint.Color;
import javafx.scene.paint.PhongMaterial;
import javafx.scene.shape.Box;
import javafx.scene.shape.DrawMode;
import javafx.scene.transform.Rotate;
import javafx.scene.transform.Translate;
import javafx.stage.Stage;public class Main extends Application {
private Thread thread;
private boolean isRunning = true;
private PerspectiveCamera camera;
private int speed = -1;
private int count = 1;
private int maxCount = 50;
public Parent createContent() throws Exception {
// Box
Box testBox = new Box(5, 5, 5);
testBox.setMaterial(new PhongMaterial(Color.BLUE));
testBox.setDrawMode(DrawMode.FILL); // Create and position camera
camera = new PerspectiveCamera(true);
camera.getTransforms().addAll (
new Rotate(-20, Rotate.Y_AXIS),
new Rotate(-20, Rotate.X_AXIS),
new Translate(0, 0, -20)); // Build the Scene Graph
Group root = new Group();
root.getChildren().add(camera);
root.getChildren().add(testBox); // Use a SubScene
SubScene subScene = new SubScene(root, 310,310, true, SceneAntialiasing.BALANCED);
subScene.setFill(Color.ALICEBLUE); subScene.setCamera(camera);
Group group = new Group();
group.getChildren().add(subScene);
return group;
} @Override
public void start(Stage primaryStage) throws Exception {
primaryStage.setResizable(false);
Scene scene = new Scene(createContent(), 300, 300);
thread = new Thread(new Runnable() {
@Override
public void run() {
while(isRunning){
try {
Thread.sleep(10);
} catch (InterruptedException e) {
e.printStackTrace();
}
Platform.runLater(new Runnable() {
@Override
public void run() {
camera.getTransforms().addAll(
new Translate(0, 0,speed));
count++;
if(count >= maxCount){
speed = -speed;
count = 0;
}
}
});
}
}
});
thread.start();
primaryStage.setScene(scene);
primaryStage.show();
}public static void main(String[] args) {
launch(args);
}
}
