3 创建World
//create a camera
camera = new Camera();
camera.setPerspective(60.0f, // field of view
(float) getWidth() / (float) getHeight(), // aspectRatio
1.0f, // near clipping plane
1000.0f); // far clipping plane
camera.setTranslation(0,0, 50);
world = new World();
world.addChild(camera);
world.addChild(mesh);
world.setActiveCamera(camera);
4 绘制World
//private Graphics3D g3d = null;
