The other reviews show a distinct lack of undertanding regarding projection and vision. While it is true that human vision is not purely rectilinear, rectilinear projection is the closest approximation of reality; especially when the field of view is not too extreme.

Most architecture involves straight lines, and most virtual tours are of architecture... preservingt these straight lines is the primary task of a panorama viewer. PMVR dispenses with this. It is the least capable panorama viewer. Showing straight lines as curves destroys the proper presentation of architecture. A better approach is to use a true spherical/cylindrical viewer, but limit the maximum FOV to 100 degrees or less. PMVR is an unimpressive and highly limiting way to view panoramas. Rectilinear projection is much better.

Most pano viewers suffer from the same strange behaveour:
-measure an object at the center of the view window
-now shift your viewpoint till the object is near the edge of the view window
-measure the same object
-it's been stretched to 2x or even 3x its size in the center of the view window.

Now rotate your head, one eye closed, keep looking straight forward but pay attention to an object that shifts through your field of view. The size remains the same, doesn't it?

PMVR tries to reach this effect by showing pano's as endless linear film strips, pulled left and right behind the view window. This does eliminate the sea-sickness effect of other pano viewers but does have another ugly effect: actual straight lines appear bent.

By FAR, this viewer (PMVR 4.5a) outperforms all others. It's hard to believe why you would use anything else. Instead of distorted, sickening views, you get crisp, clean views of your panorama as intended. It's a no-brainer.
