아래 예제를 실행하면 처음으로 3D Object를 확인 할 수 있다 ^_^ 감격의 기쁨 ~

 [ 그림 : 결과물 ]

- Scene, Camera, Viewport를 생성한다음 Object를 삽입한 이후 Rendering 한다가 기본임을 알고 넘어가면 쉽다.

 

this.addChild(_viewport);

_scene.addChild(_sphere);
_renderer.renderScene(_scene,_camera,_viewport);


1. 우리가 실제 볼 viewPort를 sprite에 넣어준다.
2. Scene에 Object를 삽입한다.
3. 우리가 지정한 Scene, Camera, Viewport 를 기준으로 렌더링을 한다.
=> 결과물은 viewport를 통해 볼 수 있게 된다.

아래 그림과 같이 차트에 그라디언트를 적용할 수 있다.
