其实就只是用到了 view.goTo() 函数，再利用 window.setInterval() 函数(定时器)定时执行goTo()。代码如下：
<!DOCTYPE html>

<head>
<meta charset="utf-8">

<title>Intro to SceneView - Create a 3D map</title>
<style type="text/css">
html, body, #viewDiv { height: 100%; width: 100%; }
#optionsDiv { background-color: white; position: absolute; left: 100px; top: 30px; z-index: 100; }
</style>
<link rel="stylesheet" href="https://js.arcgis.com/4.5/esri/css/main.css">

require([
"esri/Map",
"esri/Basemap",
"esri/views/MapView",
"esri/views/SceneView",
"dojo/domReady!"
], function (Map, Basemap, MapView, SceneView) {
var map = new Map({
"basemap": "hybrid",
"ground": "world-elevation"
});
var view = new SceneView({
"map": map,
"container": "viewDiv"
}); view.then(function () {
/**

* 指定两个点之间飞行，并按指定飞行比例的速度进行飞行
* ------------------------------------------------------------------------------------------------------------------------------------
*/
dojo.connect(dojo.byId("btnFlyTwoPoint"), "onclick", function () {
view.goTo({"zoom": 16, "tilt": 75, "center": [111.52, 28.55]})
.then(function () {
view.goTo(function () {
var camera = view.camera.clone();
camera.position.latitude += 0.11;
camera.position.longitude += 0.02;
console.info(camera.position);
return camera;
}(), {
"easing": "linear",
"speedFactor": 0.1
});
});
}); /**

* ------------------------------------------------------------------------------------------------------------------------------------
*/
var flyInterval = null;
var flyMoveUnit = 0.0001;
var flyLatitude = 27.3779;
var flyLongitude = 111.5332;
dojo.connect(dojo.byId("chkFlyAnyPoint"), "onclick", function () {
if (this.checked) {
view.goTo({"zoom": 17, "tilt": 75, "center": [flyLongitude, flyLatitude]})
.then(function () {
flyInterval = window.setInterval(function () {
flyLongitude = flyLongitude + flyMoveUnit;
flyLatitude = flyLatitude + flyMoveUnit;
view.goTo({
"zoom": 17,
"tilt": 75,
"center": [flyLongitude, flyLatitude]
});
}, 80);
}); }
else {
window.clearInterval(flyInterval);
}
});
});
});
</script>
</head>
<body>
<div id="optionsDiv">
<div>飞行模式：任意点飞行<input type="checkbox" id="chkFlyAnyPoint"/></div>
<div>飞行模式：两点之间飞行<input type="checkbox" id="btnFlyTwoPoint"/></div>
</div>
<div id="viewDiv"></div>
</body>
