I have a project and I want it to run on a PC or a mobile terminal, but different devices have different initial visible areas of the camera. How can I get this angle? For example, camera.fov defaults to 80, but it may actually only be 50 on the mobile terminal. How can I accurately obtain my current visual range?

It's hard to know without a link to code, but here's a simple way to get FOV from an A-Frame scene.

For example, on this scene: https://aframe.glitch.me/

You can open the console and type:

> AFRAME.scenes[0].camera.fov

And you'll get an answer such as:

> 80

  • Take your example, the viewing angle is 80, but my screen width becomes smaller, my actual viewing angle is not 80 – blueblueskyhua Nov 24 '20 at 07:57
