Java 3D(BeanShell)
Java 3D は Java による 3D グラフィックライブラリである。
以下は BeanShell による Java 3D の使用例となっている。
ソースコード
import javax.media.j3d.*; import javax.swing.JFrame; import javax.vecmath.Vector3f; import javax.vecmath.Color3f; import java.awt.BorderLayout; import java.awt.GraphicsConfiguration; import java.awt.Font; import com.sun.j3d.utils.universe.SimpleUniverse; class Hello extends JFrame { Hello( title ) { super(title); setSize(640, 480); setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); canvas3D = createCanvas3D(); scene = createSceneGraph(); connect(canvas3D, scene); } Canvas3D createCanvas3D() { getContentPane().setLayout(new BorderLayout()); config = SimpleUniverse.getPreferredConfiguration(); canvas3D = new Canvas3D(config); getContentPane().add(canvas3D); return canvas3D; } BranchGroup createSceneGraph() { objRoot = new BranchGroup(); mover = moveTextBack(); spinner = createSpinner(); rotator = new RotationInterpolator(new Alpha(-1, 4000), spinner, new Transform3D(), 0.0f, (float)Math.PI * 2); rotator.setSchedulingBounds( new BoundingSphere() ); spinner.addChild(rotator); objRoot.addChild(mover); mover.addChild(spinner); spinner.addChild( createTextShape()); setLighting(mover); return objRoot; } TransformGroup createSpinner() { spinner = new TransformGroup(); spinner.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE); return spinner; } TransformGroup moveTextBack() { transform3D = new Transform3D(); transform3D.setTranslation(new Vector3f(0.0f, 0.0f, -10.0f)); return new TransformGroup(transform3D); } Shape3D createTextShape() { textAppear = new Appearance(); textAppear.setMaterial(new Material()); font3D = new Font3D(new Font("MS Pゴシック", Font.PLAIN, 1), new FontExtrusion()); textGeom = new Text3D(font3D, new String("Hello, Java 3D World!")); textGeom.setAlignment(Text3D.ALIGN_CENTER); textShape = new Shape3D(); textShape.setGeometry(textGeom); textShape.setAppearance(textAppear); return textShape; } void setLighting(objMove) { light = new DirectionalLight(); light.setInfluencingBounds(new BoundingSphere()); light.setDirection(new Vector3f(0.0f,0.0f,-1.0f)); light.setColor(new Color3f(1.0f, 1.0f, 1.0f)); objMove.addChild(light); } void connect(canvas3D, scene) { universe = new SimpleUniverse(canvas3D); universe.getViewingPlatform().setNominalViewingTransform(); universe.addBranchGraph(scene); } } frame = new Hello("Hello, World"); frame.setVisible(true); |
実行方法
