Hi Cesium Team, I am now having a problem. I use "entities.add (feature)"When I did not set the terrainProvider , the added feature's location is the coordinates I provided, but after I loaded the DEM and set the terrainProvider, the added feature was offset and it's coordinates is not the coordinates that i set in "position: Cesium.Cartesian3.fromDegrees(parseFloat(val.longitude), parseFloat(val.latitude),tempheight),"
my code:/* i get the coordinates and height by click */
var camera=that.ol3d.viewer.scene.camera;
var ellipsoid = that.ol3d.viewer.scene.globe.ellipsoid;
that.handler = new Cesium.ScreenSpaceEventHandler(that.ol3d.viewer.scene.canvas);
that.handler.setInputAction(function(click) {
that.cartesian = camera.pickEllipsoid(click.position, ellipsoid);
if (that.cartesian) {
var cartographic = ellipsoid.cartesianToCartographic(that.cartesian);
var height=that.ol3d.viewer.scene.globe.getHeight(cartographic);
that.longitudeString = Cesium.Math.toDegrees(cartographic.longitude);
that.latitudeString = Cesium.Math.toDegrees(cartographic.latitude);
\('\#tempheight'\)\.html\(height\);
("#temp2").html("经度:"+that.longitudeString+",纬度:"+that.latitudeString+",高程:"+that.height)
}
}, Cesium.ScreenSpaceEventType.LEFT_CLICK);
/*then i need display the point i where i click */
var temp = \("\#temp2"\)\.html\(\);
var tempheight=("#tempheight").html();
var myarray =temp.split(/[:,]/);
result.longitude = myarray[1];
result.latitude = myarray[3];
alert(parseFloat(result.longitude)+"-=-=-"+parseFloat(result.latitude)+"高程是--"+parseFloat(tempheight))
$(result)
.each(function (i, val) {
var feature = {
parent: layer,
name: "longitude" + i,
position: Cesium.Cartesian3.fromDegrees(parseFloat(val.longitude), parseFloat(val.latitude),tempheight),
layerid:idtemp,
heightReference: Cesium.HeightReference.CLAMP_TO_GROUND,
billboard : {
image : 'images/icon/u12111.png', // default: undefined
show : true, // default
heightReference:Cesium.HeightReference.CLAMP_TO_GROUND,
eyeOffset:new Cesium.Cartesian3(0, 0,-60),
pixelOffset : new Cesium.Cartesian2(0, -10),
scale : 0.5,
horizontalOrigin : Cesium.HorizontalOrigin.CENTER
},
data: val
};
var tmpentiy = that.ol3d.viewer.entities.add(feature);
that.ol3dlist[val.stationcode] = tmpentiy;
});
/* the result.latitude , result.longitude and tempheight is just the value
where i click .when i do not set the terrainProvider,The Cesium without Terrain，the feature'location is the position i wanted .But,when i set the terrainProvider " var terrainProvider = new Cesium.CesiumTerrainProvider({
url : ‘http://localhost:8080/terrain_tiles’,
}); this.viewer.scene.terrainProvider = terrainProvider;"
the feature’coordinates is not the result.latitude and result.longitude.i don’t know why ..Please help..If you can, hope to talk directly by facebook,My account is 530109755@qq.com
