Description
With 3D PoC https://bugs.openjdk.org/browse/JDK-8295485, we can draw only one 3D primitive at a time.

If we draw more than one 3D primitive only the last drawn 3D primitive is shown.
Comments
In PoC we are creating RenderPassDescriptor in renderMeshView() and we clear color everytime and use MTLLoadActionClear, which basically overrides previously drawn Mesh. We need set 3D states in setDeviceParametersFor3D() call and reuse it for multiple renderMeshView() calls. setDeviceParametersFor3D() is called only once for multiple renderMeshView() calls.

Sample program to verify multiple 3D primitive draw: import javafx.application.Application; import javafx.geometry.Point3D; import javafx.scene.Group; import javafx.scene.Parent; import javafx.scene.Scene; import javafx.scene.shape.Box; import javafx.scene.shape.Cylinder; import javafx.stage.Stage; public class Multiple_Primitive extends Application { final int SCENE_WIDTH = 600; final int SCENE_HEIGHT = 600; public Parent createContent() throws Exception { Box testBox = new Box(SCENE_WIDTH/4, SCENE_HEIGHT/4, SCENE_WIDTH/4); testBox.setLayoutX(SCENE_HEIGHT/2); testBox.setLayoutY(SCENE_HEIGHT/2); Cylinder testCylinder = new Cylinder(100.0, 200.0); testCylinder.setLayoutX(SCENE_WIDTH/4); testCylinder.setLayoutY(SCENE_HEIGHT/2); testBox.setRotationAxis(new Point3D(1,1,1)); testBox.setRotate(45); 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); } }
