如何在javafx中在线框和实体之间切换

Question

3d 软件允许用户动态更改绘图模式。它可以在 javafx 上实现吗？

Answer 1

使用单选按钮更改绘制模式

在这种方法中，Box 实例使用单选按钮更改其 DrawMode。

这是您可以尝试的单一类 javafx。

应用程序java

public class App extends Application {

    @Override
    public void start(Stage stage) {

        var perspective = new PerspectiveCamera(true);
        perspective.setNearClip(0.1);
        perspective.setFarClip(500);
        perspective.setTranslateZ(-150);
        
        
        
        Shape3D cube = new Box(50, 50, 50);
        cube.setCullFace(CullFace.NONE);
        cube.setMaterial(new PhongMaterial(Color.CORAL));

        var toggleGroup = new ToggleGroup();
        var solid = new RadioButton("solid");
        solid.setToggleGroup(toggleGroup);
        solid.setSelected(true);
        var wire = new RadioButton("wireframe");
        wire.setToggleGroup(toggleGroup);

        var hBox = new HBox(solid, wire);

        toggleGroup.selectedToggleProperty().addListener((o) -> {
            Toggle selectedToggle = toggleGroup.getSelectedToggle();

            if (selectedToggle == solid) {
                cube.setDrawMode(DrawMode.FILL);
            }
            if (selectedToggle == wire) {
                cube.setDrawMode(DrawMode.LINE);

            }

        });

        var group3d = new Group(perspective, cube);

        var subscene = new SubScene(group3d, 300, 400, true, SceneAntialiasing.BALANCED);
        subscene.setCamera(perspective);

        var stack = new StackPane(subscene, hBox);

        stage.setScene(new Scene(stack, 300, 400));
        stage.show();
    }

    public static void main(String[] args) {
        launch();
    }

}
