Quicktime VR Panorama Viewer for the SGI
Quicktime VR (QTVR) is a file format for panoramic imagery. Viewers for
QTVR are provided by Apple for the Macintosh and MSWindows platforms. [Apple
QTVR Site] As far as I know, this page provides the only QTVR viewer
for SGI machines.
Simple QTVR Panorama Viewer
This application just reads a QTVR file and displays part of the panorama
in a window. Correct cylindrical to planar mapping is not performed. The
pixels are just pasted into the window. Use the mouse to look around. Use
the +/- keys to zoom in and out. This works great even on slow machines
like an Indy. [Implementation by James Davis]
Better QTVR Panorama Viewer
If you have a machine with texture mapping hardware, then this QTVR viewer
is preferable. It texture maps a cylider with the correct image and lets
you look around. You get better resampling and correct perspective as you
look around. An O2 seems to provide optimum viewing. [Implementation

Using the QTVR Panorama Viewer with a Web Browser
Unfortunately Quicktime Movie files and QuicktimeVR files are passed over
the net with the same MIME type, meaning that you have to set a single
helper application for both of these types. You probably want to use xanim
or movieplayer as your movie viewer, and qtvrmain for QTVR files. I use
the following shell script as a helper application to netscape. This script
determines which type of file we have and invokes the right helper application.
Note that since I'm just greping for a string, I could make the wrong choice,
but with typical file sizes this is about a 1:1000 chance, so I figure
its good enough. Files with QTVR Object Movies will go to your normal movie
player, which is actually what you want.
OUTPUT=`fgrep pano $1`
if [ "$OUTPUT" = '' ]
movieplayer -v -nofork $1
In order to test that you have your helpers configured properly here are
a few sample movies.
