Firstly, I am new at cesium.
I am stuck on a simple problem. I have a geoserver send layers and features with WMS and that is ok. My problem starts because I want display other features, like data relationships about the city that has been clicked.
In other words, I need the id of the city clicked, make a ajax with this ID to my backend server and than get other features, like relationships etc.
I have searched for a method to intercept the response of the WMS request that the cesium does, when I click on a city and parse it, for example. I havent obtained any success on that. I dont know what function does the WMS or how to overwrite it.
I try to after cesium set the selectedEntity on viewer, get the ID, but the entity comes with a ID very large and different from the database.
I try to set infobox to false and get the object with scene.pick(click.positon), but always return undefined.
Sorry if the question was confusing. I have no clue how to do that.
Thanks for the help
