    //the offset use to translating texture
    _cylinder_texture_offset = 0;
    _shining_duration = 0;
    Size visibleSize = Director::getInstance()->getVisibleSize();
 
    //use custom camera
    auto camera = Camera::createPerspective(60, visibleSize.width / visibleSize.height, 0.1f, 200);
    camera->setCameraFlag(CameraFlag::USER1);
 
    //create cylinder
    auto cylinder = Sprite3D::create("Sprite3DTest/cylinder.c3b");
    auto mat = Sprite3DMaterial::createWithFilename("Sprite3DTest/UVAnimation.material");
    _state = mat->getTechniqueByIndex(0)->getPassByIndex(0)->getProgramState();
    cylinder->setMaterial(mat);
 
    this->addChild(cylinder);
    this->setCameraMask(2);
    this->addChild(camera);
 
    //adjust cylinder's position & rotation
    cylinder->setPosition3D(Vec3(0.0f, -15.0f, -50.0f));
    cylinder->setRotation3D(Vec3(-90.0f, 0.0f, 0.0f));
