How do you create a 360° virtual tour without a fisheye lens?

What you're missing is a lot of scene coverage. To get a 360ºx180º full spherical view, you have to cover the entire sphere. Without a fisheye lens, this is likely to mean multiple rows as well as a ...

How can I align two panoramic images?
