how to make a curved plane in threejs

Question

I am projected a video into 3d geometry using threejs. The footage is from a gopro, so it's got a field of view of maybe 120degrees, so what I want is to be looking as if the footage were wrapped such that it bent a little at the sides, top and bottom (like looking from the inside of a sphere and the video were wrapped around only a portion of that sphere.

I've tried using a torus and sphere, but since the video doesn't completely wrap, it doesn't do quite what I want. Any ideas?

Answer 1

You probably should try to look for the right equation but, by the time being, you should be able to get something working with something like this:

new THREE.SphereGeometry(75, 16, 8, 0, 2, 1, 1.2);
