Although PTGui does not create QTVR panoramas directly, you can create a spherical panorama with PTGui and convert it to Quicktime VR format using third party QTVR software. On the Panorama Settings page in PTGui select equirectangular, 360 x 180 degree, JPEG and use a tool like PanoCube QTVR software to convert to QTVR format.
PTGui is a front end for Panorama Tools, the powerful panoramic imaging software written by dr. Helmut Dersch.
PTGui makes it easy to use the otherwise difficult to use Panorama Tools. Both the PTGui software
and Panorama Tools can be downloaded from this site, see the download page.
PTGui and Panorama Tools can correct lens distortion, use multiple rows of images and stitch tilted images.
