Cubic Projection A spherical panorama can be converted to 6 cubefaces which can be displayed as a Cubic QTVR or in other viewers which support cubic projection like Macromedia Shockwave. The cube faces are actually 90x90 degrees rectilinear images like the ones you get from a normal lens.
I got this from this website: http://www.panoramas.dk/quicktime
Does anyone have any idea if that is true, if you can have a cubic image display in flash?

The SPi-V Shockwave Player from Aldo Hoeben is great for ADR and HDR panos. Running this panos from CD works very good, but for the web the user needs quite always to install the Shockwave plugin.
Bernhard Vogl has some nice demos:
This is really good compromise that supports 360 - ok its not QT, but so what. You can view it as a standard 360 cylindrical image, or use keypoints, or use a mouse controled view which gives a spherical feel; so it isn't perfect but it is flexible, best i've come across anyway. Download the demo and have a play.
