我喜欢 Sergey 的解决方案,它非常巧妙地使用了 ScaleTransition,并且在 2D 中工作意味着您不需要处理 3D 的一些复杂性。
这里有几个 3D 旋转示例。
围绕 Y 轴旋转 2D 节点(ImageView)(需要 JavaFX 2.2 + 3D 支持)。
import javafx.animation.*;
import javafx.application.Application;
import javafx.scene.*;
import javafx.scene.image.*;
import javafx.scene.layout.StackPane;
import javafx.scene.transform.Rotate;
import javafx.stage.Stage;
import javafx.util.Duration;
public class QuickFlip extends Application {
@Override
public void start(Stage stage) throws Exception {
Node card = createCard();
stage.setScene(createScene(card));
stage.show();
RotateTransition rotator = createRotator(card);
rotator.play();
}
private Scene createScene(Node card) {
StackPane root = new StackPane();
root.getChildren().addAll(card);
Scene scene = new Scene(root, 600, 700, true, SceneAntialiasing.BALANCED);
scene.setCamera(new PerspectiveCamera());
return scene;
}
private Node createCard() {
return new ImageView(
new Image(
"http://www.ohmz.net/wp-content/uploads/2012/05/Game-of-Throne-Magic-trading-cards-2.jpg"
)
);
}
private RotateTransition createRotator(Node card) {
RotateTransition rotator = new RotateTransition(Duration.millis(10000), card);
rotator.setAxis(Rotate.Y_AXIS);
rotator.setFromAngle(0);
rotator.setToAngle(360);
rotator.setInterpolator(Interpolator.LINEAR);
rotator.setCycleCount(10);
return rotator;
}
public static void main(String[] args) {
launch();
}
}
围绕 Y 轴旋转 3D 节点(TriangleMesh)(需要 Java 8 + 3D 支持)。
