At the moment, we offer creating spherical panoramas in several sizes ‒ 32, 128, 365 megapixels and 1 gigapixel (8000x4000, 16000x8000, 27000x13500 and 45000x22500 pixels accordingly). Panoramas with all of the specified dimensions are guaranteed high quality for viewing on the FullHD monitors with full screen mode. At that, panoramas with maximum size (1 gigapixel) is provided with the highest image sharpness, even if high zoom is used.
Thanks to multiresolution viewing technology, even panoramas with such a big sizes can be easily viewed on any PC or mobile devices.
For illustration of the point, just below there are some pictures where the difference between panorama resolutions is shown. On the first image one can see a comparison between the sizes of spherical panoramas in equirectangular projection.
On the next image a visual quality of different panoramas with equal zooming is demonstrated (zoomed area is marked with red rectangle on spherical panorama).
