Hello,

I have built a simple flight simulator, but there is a problem with the horizon - it change its position when  
I resize the browser’s window or I change the altitude or the roll of the airplane. How can I fix this?

Greetings!

I’m curious about how you implemented the horizon line in your project. Could you share some details on the approach you used?
