PMVR 6.4a is a Panorama product from duckware.com, get 4 Stars SoftSea Rating, PMVR is a Java applet that displays 360 degree panoramic images in a web page and in full screen mode (great performance, even on 2560x1600 displays) - a outstanding alternative to QTVR (QuickTime VR) for creating large multi-node virtual tours.
PMVR was designed to be small, fast, and multi-platform. When used with the optional floor plan applet, you can create incredible walk-throughs of homes or other "mappable" environments.
When you move the panorama, you see a highlight change on the associated map/floorplan, visually showing you the field-of-view seen in the panorama). Full integration with JavaScript allows for outstanding customization by you or your web master.
The included VirtualTourEditor.exe (Windows only) makes authoring your virtual tour as simple as a couple of mouse clicks. Just import your panoramas, set titles, create hot spots, and publish.
Really large panoramas are fully supported. Use the mouse wheel to quick zoom in and out of the panorama. When panoramas larger than the viewer window are used, zooming in results in the end-user seeing more and more detail as they zoom in. Visit the top of PMVR manual web page (www.duckware.com/pmvr/index.html) for many example virtual tours. Several of the sample tours feature large (5600x1000) high-definition panoramas.
The resulting virtual tour is very crisp and clear and looks amazing in full-screen mode -- simply stunning when viewed full screen on a large 30" 2560x1600 display, such as Apples Cinema display. The trial download includes several sample panoramas, which allows you to immediately launch the VirtualTourEditor.exe and produce your first virtual tour in a matter of seconds.
