QuickTime VR (also known as QTVR) is an image file format developed by Apple Inc. for QuickTime, and discontinued along with QuickTime 7. It allows the creation and viewing of VR photography, photographically-captured panoramas, and the exploration of objects through images taken at multiple viewing angles. Supported up to the discontinued QuickTime version 7, QuickTime VR functions as a plugin for the standalone QuickTime Player, as well as working as a plugin for the QuickTime Web browser plugin.


QuickTime VR was developed starting in 1991 by the Human Interface Group at Apple, utilizing a Cray supercomputer to process images into panoramas. It was soon made prominent within the company by Apple's board member and former astronaut Sally Ride, who was fascinated by the demonstrated possibilities of 3D computer imagery.[2]

The first way I did panoramic photography was a little bit of a cheat. So what you do is, you take a million pictures and you animate between them. I did all this with a single camera, because imagining the matrix of cameras we now use was just too expensive. It was extremely onerous, the stitching and all of that. It was quite a lot of work. The head-mounted VR did exist at that time. So it was a poor man's VR. Calling it VR was controversial and somewhat presumptuous.

-- Dan O'Sullivan, early QuickTime VR engineer[2]

The technology was publicly launched in 1995 and then deemphasized upon the return of Steve Jobs to Apple in 1997. In its lifespan, it was used as supporting technology in many digital publications such as the Star Trek: The Next Generation Interactive Technical Manual.[2] The first high-profile application of QuickTime VR was in the 1995 courtroom visualization of the crime scenes in the O. J. Simpson murder case.[3]

It's difficult not to read about Apple's experiments with panoramic images and not draw a connection to the recent rise of 360-degree videos on platforms like Facebook and YouTube -- or even the immersive aspects of services like Google Maps Street View. Much of what's called VR these days isn't a full interactive environment, but is instead a descendant of the panoramic images that Apple pioneered.

The discontinuation of QuickTime 7 in the late 2000s brought the end of development and support of QuickTime VR and other major technologies.



Panoramas are panoramic images which surround the viewer with an environment (inside, looking out), yielding a sense of place. They can be stitched together from several normal photographs or 2 images taken with a circular fisheye lens, or captured with specialized panoramic cameras, or rendered from 3D-modeled scenes. There are two types of panoramas:

  • Single row panoramas, with a single horizontal row of photographs.
  • Multi-row panoramas, with several rows of photographs taken at different tilt angles.

Panoramas are further divided into those that include the top and bottom, called cubic or spherical panoramas, and those that do not, usually called cylindrical.

Example of a cylindrical panorama. Taken with a Nikon Coolpix 5000 and stitched with Apple Inc.'s QuickTime Authoring Studio.

A single panorama, or node, is captured from a single point in space. Several nodes and object movies can be linked together to allow a viewer to move from one location to another. Such multinode QuickTime VR movies are called scenes.

Apple's QuickTime VR file format has two representations for panoramic nodes:

Each of these are typically subdivided or tiled into several smaller images, and stored in a special kind of QuickTime movie file, which requires the QuickTime plugin.

Hot spots can be embedded into the panorama, which when selected can invoke some action, for example moving to another panorama node.

Example of a cylindrical panorama. Taken with a Canon Digital Rebel XT


In contrast to panoramas, which are captured from one location looking out at various angles, objects are captured from many locations pointing in toward the same central object.

The simplest type of objects to capture are single row, typically captured around the equator of an object. This is normally facilitated by a rotating turntable. The object is placed on the turntable, and photographed at equal angular increments (usually 10°) from a camera mounted on a tripod.

Capturing a multi-row object movie requires a more elaborate setup for capturing images, because the camera must be tilted above and below the equator of the object at several tilt angles.

The image source does not have to be photographic. 3D renderings or drawings can be used.
