FSPViewer is a Photo & Image software developed by Fulvio Senore. After our trial and test, the software is proved to be official, secure and free. Here is the official description for FSPViewer:
Edit By BS Editor: FSPViewer is a Free Viewer for spherical (equirectangular) panoramic images.
There already many viewers available, so let's start from what FSPViewer is not. It is not a program for viewing panoramas on the internet.
FSPViewer is designed for viewing local (hard-disk, network or CD) high resolution panoramic images at full screen and with very high image quality. It uses advanced interpolation algorithms to show you smooth images without losing sharpness.
Internet viewers are designed for displaying small images in small windows, since bandwidth is limited. Viewing a Panorama at full screen will give you a much more immersive feeling, but it will require much more resources from the computer. The whole image will be loaded in memory and the program will need to write a very high number of pixels, so a fast processor will be needed for smooth panning.
Today's (and tomorrow's) computers have fast processors and a lot of RAM, so it's Now possible to write a full screen viewer. FSPViewer can handle images limited only from the available RAM and is heavily optimized so it's fast enough on Modern computers. It can even use both processors of a dual core CPU like most modern ones.
FSPViewer does not require installation, just run it and look at the panorama. It supports hotspots so you can create virtual tours and distribute them on a CD. Every Windows computer will be able to run it immediately.
What's new in version 1.51? Fixed: hotspots very near to zenith or nadir did not show correctly. Added a command line switch to start the viewer in full screen. Now pressing the "F" key will show the panoramic image in full-screen mode. This is a Keyboard Shortcut for the command introduced in the previous version. you can free download FSPViewer 1.51 now.
