Mouse pointer position in latitude and longitude

[shujaatak]

Can you please tell me how to print the mouse pointer position in latitude and longitude in the console when I move mouse over the globe? Actually I can't work out the inverse transformation properly and you might help in this regard please.

It's an abandoned project that I haven't touch for almost a year now and it's really difficult to quickly give you an exact answer. I've had a look at this and can provide only the following guidance:

• inverse transformation is done in Projector: https://github.com/green-anger/GlobeViewer/blob/e95ece3158bc8ffd02782b7bc7ce65814eb83697/lib/src/Projector.cpp#L107
• there's no API method to get lon/lat at the current cursor position, you'll have to use this: https://github.com/green-anger/GlobeViewer/blob/e95ece3158bc8ffd02782b7bc7ce65814eb83697/lib/src/GlobeViewer.cpp#L63 Since it's in GlobeViewer.cpp you can add an API method sending {x, y} and getting {lon, lat} pair in return using projector. Just don't forget to check return value for projectInv, false means you're out of the Globe (check the docs).

Hope that helps.

Thank you so much for these pointers, I am going to try these pointers and hopefully will achieve what I want. You are the best!
