<pre><code class="language-javascript">// 示例1
// 相机直接飞入北京(116.39, 39.9)的位置，高度100米。相机位于目标点上。
earth.camera.flyTo([116.39*Math.PI/180, 39.9*Math.PI/180, 100])
// 示例2
// 相机直接飞向北京(116.39, 39.9)的位置，高度100米的目标，再距离目标点1000米的距离停下来，此时目标点刚好位置屏幕中心位置。
earth.camera.flyTo([116.39*Math.PI/180, 39.9*Math.PI/180, 100], 1000);
// 示例3
// 相机直接飞向北京(116.39, 39.9)的位置，高度100米的目标，再距离目标点1000米的距离停下来，此时目标点刚好位置屏幕中心位置。
// 同时相机的方向是正东向，向下倾斜30度。
// 相机方向是这样的 朝北是0度，朝东是90度，朝南是180度，朝西是270度。抬头看天的俯仰角是90度，俯视地面是-90度。
earth.camera.flyTo([116.39*Math.PI/180, 39.9*Math.PI/180, 100], 1000, [90*Math.PI/180, -30*Math.PI/180, 0]);
// 特别说明：
// 注意示例中使用度数是方便理解，实际使用时，需要转换成弧度（乘上Math.PI/180)
// 为了和Cesium保持一致(Cartographic，Cartesian)，EarthSDK里面凡是涉及到角度的单位一律用弧度，凡是使用长度的单位一律用米。
// 实际上计算机地层中关于角度的计算都是使用弧度的，比如JS中的Math.cos/Math.sin等所有的角度计算操作。</code></pre>
