new Cesium.GeoRoveFly(options)

Name Type Description
options Object optional 参数选项：
Name Type Default Description
viewer Viewer optional 三维球
path Array optional 飞行路径的节点数组，每个节点包括坐标和方向，例如[{position: Cesium.Cartesian3.fromDegrees(114.39, 30.47, 272.46),direction: new Cesium.Cartesian3(-0.5483434682364607, -0.8139196091849253, 0.19197476559868001),up: new Cesium.Cartesian3(-0.5835248610655802, 0.5368464509435076, 0.6093394986604392)},...]
duration Number (path.length-1)/0.2 optional 飞行时间，单位秒
interpolationDegree Number 2 optional 埃尔米特多项式插值函数的插值次幂。值越大，则插值后的路线越平滑，相应地飞行时会有更少的卡顿感，但同时也会更偏离预定路线。
loop Boolean false optional 是否循环飞行
pathShown Boolean false optional 是否显示飞行路径
pointShown Boolean false optional 是否显示节点
