Currently after https://bugs.openjdk.org/browse/JDK-8295485 and https://bugs.openjdk.org/browse/JDK-8301597 we can see 3D primitives getting drawn. But since we dont have any light support we can't see 3D constructs of the primitve.

By default JavaFX adds single point light as default light. Implement the same as first step in 3D lightning support in Metal.

Sample Program to verify single point light implementation : import javafx.application.Application; import javafx.geometry.Point3D; import javafx.scene.Group; import javafx.scene.Parent; import javafx.scene.Scene; import javafx.scene.paint.Color; import javafx.scene.paint.PhongMaterial; import javafx.scene.shape.Box; import javafx.scene.shape.Cylinder; import javafx.stage.Stage; public class SingleLight_3D extends Application { final int SCENE_WIDTH = 600; final int SCENE_HEIGHT = 600; public Parent createContent() throws Exception { int denom = 4; Box testBox = new Box(SCENE_WIDTH/denom, SCENE_HEIGHT/denom, SCENE_WIDTH/denom); testBox.setLayoutX(SCENE_HEIGHT/2 + 100); testBox.setLayoutY(SCENE_HEIGHT/2); testBox.setRotationAxis(new Point3D(1,1,1)); testBox.setRotate(45); testBox.setMaterial(new PhongMaterial(Color.RED)); Cylinder testCylinder = new Cylinder(100.0, 200.0); testCylinder.setLayoutX(SCENE_WIDTH/4); testCylinder.setLayoutY(SCENE_HEIGHT/2); testCylinder.setRotationAxis(new Point3D(1,1,1)); testCylinder.setRotate(45); Group root = new Group(); root.getChildren().add(testBox); root.getChildren().add(testCylinder); return root; } @Override public void start(Stage primaryStage) throws Exception { Scene scene = new Scene(createContent(), SCENE_WIDTH, SCENE_HEIGHT); primaryStage.setScene(scene); primaryStage.show(); } /** * Java main for when running without JavaFX launcher */ public static void main(String[] args) { launch(args); } }
