Java 可以通过使用 OpenGL 或 Java3D 库实现 3D 界面。以下是一个使用 Java3D 库实现 3D 界面的示例代码:
```java
import java.awt.BorderLayout;
import java.awt.GraphicsConfiguration;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.media.j3d.BranchGroup;
import javax.media.j3d.Canvas3D;
import javax.media.j3d.DirectionalLight;
import javax.media.j3d.PolygonAttributes;
import javax.media.j3d.Shape3D;
import javax.media.j3d.Transform3D;
import javax.media.j3d.TransformGroup;
import javax.swing.JFrame;
import javax.vecmath.Color3f;
import javax.vecmath.Point3d;
import javax.vecmath.Vector3d;
import com.sun.j3d.utils.geometry.Box;
import com.sun.j3d.utils.geometry.Cone;
import com.sun.j3d.utils.geometry.Cylinder;
import com.sun.j3d.utils.geometry.Sphere;
import com.sun.j3d.utils.geometry.Torus;
import com.sun.j3d.utils.universe.SimpleUniverse;
public class Java3DExample extends JFrame {
private static final long serialVersionUID = 1L;
public Java3DExample() {
super("Java3D Example");
// Creating the 3D canvas
GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration();
Canvas3D canvas = new Canvas3D(config);
getContentPane().add(canvas, BorderLayout.CENTER);
// Creating the Simple Universe and the Branch Group
SimpleUniverse universe = new SimpleUniverse(canvas);
BranchGroup group = new BranchGroup();
// Creating the Shapes
Box box = new Box(0.3f, 0.3f, 0.3f, Box.GENERATE_TEXTURE_COORDS, null);
Cone cone = new Cone(0.3f, 0.5f);
Cylinder cylinder = new Cylinder(0.3f, 0.5f);
Sphere sphere = new Sphere(0.4f);
Torus torus = new Torus(0.2f, 0.4f);
// Setting Attributes for the Shapes
Color3f color = new Color3f(0.7f, 0.7f, 0.7f);
PolygonAttributes polyAttributes = new PolygonAttributes();
polyAttributes.setPolygonMode(PolygonAttributes.POLYGON_FILL);
polyAttributes.setCullFace(PolygonAttributes.CULL_NONE);
Shape3D shape = box.getShape(Box.FRONT);
shape.setAppearance(shape.getAppearance());
shape.getAppearance().setPolygonAttributes(polyAttributes);
shape.getAppearance().getColoringAttributes().setColor(color);
shape = cone.getShape();
shape.setAppearance(shape.getAppearance());
shape.getAppearance().setPolygonAttributes(polyAttributes);
shape.getAppearance().getColoringAttributes().setColor(color);
shape = cylinder.getShape(Cylinder.BODY);
shape.setAppearance(shape.getAppearance());
shape.getAppearance().setPolygonAttributes(polyAttributes);
shape.getAppearance().getColoringAttributes().setColor(color);
shape = sphere.getShape();
shape.setAppearance(shape.getAppearance());
shape.getAppearance().setPolygonAttributes(polyAttributes);
shape.getAppearance().getColoringAttributes().setColor(color);
shape = torus.getShape();
shape.setAppearance(shape.getAppearance());
shape.getAppearance().setPolygonAttributes(polyAttributes);
shape.getAppearance().getColoringAttributes().setColor(color);
// Adding the Shapes to the Branch Group
Transform3D transform = new Transform3D();
TransformGroup tg = new TransformGroup(transform);
tg.addChild(box);
group.addChild(tg);
transform = new Transform3D();
transform.setTranslation(new Vector3d(0.0, -0.6, 0.0));
tg = new TransformGroup(transform);
tg.addChild(cone);
group.addChild(tg);
transform = new Transform3D();
transform.setTranslation(new Vector3d(0.0, 0.6, 0.0));
tg = new TransformGroup(transform);
tg.addChild(cylinder);
group.addChild(tg);
transform = new Transform3D();
transform.setTranslation(new Vector3d(-0.6, 0.0, 0.0));
tg = new TransformGroup(transform);
tg.addChild(sphere);
group.addChild(tg);
transform = new Transform3D();
transform.setTranslation(new Vector3d(0.6, 0.0, 0.0));
tg = new TransformGroup(transform);
tg.addChild(torus);
group.addChild(tg);
// Creating and Adding Light to the Branch Group
DirectionalLight light = new DirectionalLight(new Color3f(1.0f, 1.0f, 1.0f), new Vector3d(-1.0, -1.0, -1.0));
light.setInfluencingBounds(new javax.vecmath.BoundingSphere(new Point3d(0.0, 0.0, 0.0), 100.0));
group.addChild(light);
group.compile();
// Setting the View Point
universe.getViewingPlatform().setNominalViewingTransform();
universe.addBranchGraph(group);
// Window listener to close the window
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent event) {
dispose();
System.exit(0);
}
});
// Setting the Size of the Window
setSize(400, 400);
setVisible(true);
}
public static void main(String[] args) {
Java3DExample example = new Java3DExample();
}
}
```
此示例代码会创建一个包含五个不同形状的 3D 对象,并添加了一个满足所需挑战的光源,最后输出一个 3D 界面。
