Operating keys or a mouse, perhaps, according to the wish, to look round around or to turn back, bring closer or distance the interesting subject, to develop the picture under the necessary corner.
Such interactivity virtual 3D - panoramas creates effect of presence. This significant advantage which distinguishes virtual spherical panoramas from other visualization tools.
Several panoramic photos can be connected "active zones" on which it is possible to move from one 3D - panoramas in another. It is called virtual round (see examples: virtual rounds on the basis of 360-degree photopanoramas).
Virtual round, as well as separate 3D - panoramas, can include Flash-animation, a soundtrack and other multimedia elements. Creation of virtual rounds and 360-degree spherical 3D - panoramas - an effective way of drawing attention in various business - projects. This decision already found application in spheres: real estate, construction, restaurant and hotel business, interior design, show business and tourism, and many other spheres.
