# cesium-控件介绍

# 控件介绍

cesium默认会加载很多控件，如图所示

geocoder: 位置查找工具
baseLayerPicker: 图层选择器（地形影像服务）
timeline: 底部时间线
homeButton: 视角返回初始位置
fullscreenButton: 全屏
animation: 左下角仪表盘（动画器件）
sceneModePicker: 选择视角的模式（球体、平铺、斜视平铺）
navigationHelpButton: 导航帮助按钮
infoBox: 信息框控件
navigationInstructionsInitiallyVisible: 导航说明初始可见
shouldAnimate: 动画
requestWaterMask: 请求水面罩
requestVertexNormals: 请求顶点法线

所有的控件都是可以关闭的
