hi,
For interior scenes , the objects are around a point, so one interactive panorama can show an interior of a room. But in the case of exterior you need to have panorama at different points(showing one at a time) to completely show the exterior of a house or something.You can use pano2vr program for such.

Or the next solution is realtime interactive using 3d engines like unity.See the example from me.
