Interactive Three.js globe - Click on countries for information

I have successfully implemented rotation and animation for a 3D earth using three.js by applying a world map image texture to a sphere as detailed in the tutorial found at this specific link. My goal is to make each country on the globe clickable, so that when a user clicks on a country, its border will be highlighted and a pop-up will display the country's name. I believe I may need to utilize d3.js to load a GeoJSON file of countries and incorporate it as a mesh in three.js. However, I am unsure how to accomplish this through coding.

Can anyone provide assistance with this?

Answer №1

If you need to determine which country has been clicked, one option is to utilize Google's geocoding service:

"http://maps.googleapis.com/maps/api/geocode/json?latlng=" + lat + "," + lon + "&sensor=false";

Check out a working example at . This method may not be useful for identifying country borders. Alternatively, consider using the technique showcased in where each country is represented as a separate object.
