cesium开发笔记

1.根据经纬度定位 Cesium.Cartesian3.fromDegrees(,)
2.根据xy坐标定位Cesium.Cartesian2(x,y) Cesium.Carteian3(x,y,z)
var bluebox=viewer.entities.add({
name:'bluebox',
position:new Cesium.Cartesian3.fromDegrees(-114.0, 40.0, 300000.0),
box :{
dimensions :new Cesium.Cartesian3(1000000.0, 5000000.0, 500000.0),
material:Cesium.Color.BLUE,
outline:true,
outlinecolor:Cesium.Color.BLACK,
}
});
3.二维转换的方法
var view = new Cesium.Viewer('cesiumContainer',{
sceneMode:Cesium.SceneMode.SCENE2D,
sceneModePicker:false
})
4.entities方法加入图形
5viewer.imageryLayers.addImageryProvider(new Cesium.GridImageryProvider());经纬网
