Converting Latitude and Longitude into a 3D point using three.js

Is there a function available in three.js that can determine the inverse of azimuth and inclination for PolyhedronGeometry calculations? Essentially, I am looking to find the 3D point at a specific angle from the origin based on azimuth and inclination values.

If such a function exists in three.js already, please let me know. Thank you.

Answer №1

In addition to considering the angles of azimuth and elevation, it is crucial to also factor in the distance in order to accurately pinpoint a 3D point; otherwise, you would merely have a line or direction.

If you are aware of the distance from the origin denoted as R, along with the values of θ (azimuth) and ϕ (elevation), you can determine the 3D coordinates through the following equations:

x = R*cos(ϕ)*sin(θ)
y = R*cos(ϕ)*cos(θ)
z = R*sin(ϕ)

This explanation should provide some clarity on the process.
