    I am undertaking a virtual tour of a small museum with several very large rooms. To get better resolution of the panorama I am thinking of using a 15mm lens instead of an 8mm fisheye.The tricky part will be shooting the nadir shots to eliminate the tripod. I have not done this before. I use 3DVISTA for the tour and PTGui for the panoramas.
    Will using a wide angle lens in lieu of a fisheye produce a tour which can let users get closer to objects in a very large room?
    Thanks for your help

    Yes, that will definitely work and is common practice.
    The question is, what is a very large room? And will the 15mm deliver sufficient resolution. You then even can get longer wiring your lenses. Is this a fullframe fisheye or a 15mm lens with rectilinear projection?

    Patching nadir is not a problem, you shoot as in the tutorials for ptgui and use viewpoint correction.

    I use Pano2VR to build my tours where nadir patching works like a charm. But you also can use any other image editor of your choice. I think there even is a tutorial for patching with the help of ptgui.

    Thank you Jürgen. I am opt for a longer lens. The museum is an old fort that houses a very large cannon, a 16 inch gun from a WWII battleship.
