JavaFX Light.Point效果

在这种照明效果下，将光源在3D空间中指定位置。顾名思义，光源位于某个点，并且将节点缝合以从该特定光源变亮。类javafx.scene.effect.Light.Point表示此光源。我们需要实例化此类，以便在节点上生成适当的光照。

物产

下表描述了类的属性及其设置方法。

Property	Description	Setter Methods
X	It is a double type property. It represents the X coordinate of the Light source.	setX(Double value)
Y	It is a double type property. It represents the Y Coordinate of the light source.	setY(Double value)
Z	It is a double type property. It represents the Z coordinate of the light source.	setZ(Double value)

建设者

该类包含两个构造函数

public Light.Point()：使用默认参数创建新实例。
Public Light.Point(double x，double y，double z，Color color)：使用指定的3D坐标和灯光颜色创建新实例

例：

package application;
import javafx.application.Application;
import javafx.geometry.VPos;
import javafx.scene.Group; 
import javafx.scene.Scene;
import javafx.scene.effect.Light;
import javafx.scene.effect.Lighting;
import javafx.scene.paint.Color;
import javafx.stage.Stage; 
import javafx.scene.text.Font; 
import javafx.scene.text.FontWeight; 
import javafx.scene.text.Text; 

public class LightingExample1 extends Application { 
@Override
public void start(Stage stage) {  
Text text = new Text();       
text.setFont(Font.font(null, FontWeight.BOLD, 40));        
text.setX(50); 
text.setY(40); 
text.setTextOrigin(VPos.TOP);
text.setText("HELLO WORLD!!");        
text.setFill(Color.RED);   
Light.Point light = new Light.Point();
light.setX(0);
light.setY(0);
light.setZ(-100);
Lighting lighting = new Lighting(); 
lighting.setSurfaceScale(5);
text.setEffect(lighting);       
Group root = new Group();
root.getChildren().add(text);
Scene scene = new Scene(root, 500, 200);  
stage.setTitle("light.Point example");  
stage.setScene(scene);
stage.show();         
} 
public static void main(String args[]){ 
launch(args); 
} 
}
