Click and find Latitudes & Longitudes
This code was inspired by and heavily based on @prisoner849 ´s special work "Sphere of separate quads … Sphere of separate quads.
There I found a way to click on a point on the Earth, get the coordinates of the point, and transform them into latitude and longitude.
In the code You will find some interesting URL´s to find references.
Three.js Forever !!!
Here is a challenge for you:
Try to do the same without any trigonometry and without quads.
Hi @PavelBoytchev …
Thanks for the ear tugging…
I just discovered the ‘.point’ property of raycasting !!!
So, I do not need quads…
Now I will try to find how to not use trigonometry to convert x y and z to latitude and longitude.
Thank You very much for the attention!
PS1: My first thought was to use RFIDs, but I found it too expensive!
PS2: Maybe I need an Educator for the next step!
PS3: Please see the link:
Please observe the differences between latitudes in p and in pp.
pp is done with

Of course I had to do some adjusts in the equations to calculate trigonometric functions.
PS4: IMPORTANT… made corrections in North and South Signs (+ and -) according the errors obsevations made by @PavelBoytchev … and Thanks for that!
