Another panorama viewer? Well, yes, I think some of you might be interested in this one. It began as an exercise for learning Qt and OpenGL, which I hoped might produce a useful viewer for Linux. But it works so well (on the right hardware) that I've decided to release it to the world (https://sourceforge.net/projects/pvqt/).
pvQt uses the advanced texture mapping capabilities of OpenGL version 2.0 or better, to generate true 3D views: the panorama is projected on a cylinder or sphere, whose interior is seen in perspective from a movable point of view. That makes it possible to rotate the view in all 3 dimensions (yaw, pitch, and roll) and to change the perspective continuously from rectilinear (when the eye is at the center) through increasingly "fisheye-like" views, out to a "super fisheye" that can show almost 288 degrees of the panosphere. At present pvQt only knows how to display spherical panoramas, in equirectangular or cubic formats (including cubic QTVRs). But it is designed to handle all the common pano formats and show "flat" photos too. It has a few glitches, the worst of which is that it can't tell whether it is running on an OpenGL implementation that actually supports it -- if not, it just shows all white images. Building pvQt requires the Qt development framework, which is huge but reliable and easy to use, and zlib, which is tiny and ubiquitous. There is a prebuilt win32 (MinGW) executable on SF, along with the needed MinGW and Qt DLLs. It is in a self extractor that only runs on Windows, but soon there will be a source tar too. And you can check out the source tree with "svn co https://pvqt.svn.sourceforge.net/svnroot/pvqt pvqt ".
