I think I understand how they’re recorded using a spherical camera, but how do people make 360 videos with 3D modeled environments and things like that?

One way is to use a [parabolic mirror](https://books.google.com/books?id=Vi-qCAAAQBAJ&pg=PA61&lpg=PA61&dq=parabolic+mirror+360). You photograph straight up into a curved mirror which gives you a distorted image with a 360° field of view. Software can then fairly simply undo the distortion. While the horizontal field of view is 360°, this approach can’t see straight up or down; the vertical field of view is only about 100°.
With 3D modeled environments it’s actually easier, because you don’t need to buy a special camera. 3D modeled means the video was computer generated. If your software supports it, you can simply tell the computer to render all the directions. Normally you’d set up a virtual camera and tell the computer to render what the camera can see.
it is typically recorded using either a special rig of multiple cameras, or using a dedicated camera that contains multiple camera lenses embedded into the device, and filming overlapping angles simultaneously. … Generally, the only area that cannot be viewed is the view toward the camera support.
