QTVR

QuickTime Virtual Reality or QTVR is what a large section of people seem to class as VR. Whilst QTVR does bear a similarity to a static shot from a CAVE, or a static skybox, this display method is not truly virtual reality in any meaningful form.

QTVR can be best described as a series of still shot montages, six photos comprising six views of a scene - four walls surrounding you, a ceiling and a floor, all taken from the precise point they are trying to recreate, to give you a feeling of immersion within that space.

QTVR works fairly well excepting that the reality it creates is totally static - you can neither move away from the point you are standing in, nor can you modify the environment in any way. You may simply zoom in, or zoom out of any part of the cube, or rotate to look at it from any angle. That is the limit of the interaction.

Walkthroughs of a sort are made in QTVR by stringing together a series of cube images and allowing the viewer to flip between them. You can for example move from the front room to the hall, by unloading the images of a set point in the front room from the cube, and loading the images of a set point in the hall. This results in little more than a picture tour of a place, from single, isolated points of view.
