I have been searching for an example of plotting a point/marker in space given the latitude, longitude and altitude/elevation but i cannot find it in the documentation or on any other question. Is it possible to plot a marker in space using WebGL-earth?

  • you might find [this tutorial useful](https://threejsfundamentals.org/threejs/lessons/threejs-optimize-lots-of-objects.html), it's followed by 3 more tutorials all related to making WebGL Earth like stuff – gman Mar 14 '19 at 15:10
  • I am struggling to solve same issue in CesiumJS, did you find a solution? – jumpjack Nov 25 '20 at 09:17
  • @jumpjack i managed to find a solution using CesiumJS. Im not sure if it will help you but maybe look into the Cesium.Cartesian3.fromDegrees. It solved my issues. `item.position=Cesium.Cartesian3.fromDegrees(lon_coordinates,lat_coordinates,alt_coordinates); ` – Owen Nov 26 '20 at 10:22
  • but this gives you only the ability to locate a point on surface! But maybe I misunderstood: by altitude/elevation you meant height above ground, while I meant angular elevation, as in "altitude/azimuth coordinate system". – jumpjack Nov 26 '20 at 10:44
  • I couldn't find anything for azimuth so I had converted my data to work with this method. Not the greatest solution but it was a workout that worked for my project. – Owen Nov 27 '20 at 11:10
