 This code creates a 360 image panorama. The first panorama added to the viewer will be the entry point. To link panoramas, simply use `panorama.link( other_panorama )` to connect the two. See [examples](http://pchen66.github.io/Panolens/) and [documentation](http://pchen66.github.io/Panolens/docs/index.html) for more details.

 Move cursor on a specific point in a panorama and press `Ctrl` with mouse clicking or hovering, which will generate position (x, y, z) in the console. See [Panorama Infospot](http://pchen66.github.io/Panolens/examples/panorama_infospot.html) example for creating and attaching infospots.
