Photo Zoomer

[Peter Bogdanoff]

In the past I’ve used QuickTime VR for projects such as this.

You can zoom in and out, fly around a very large map or image, click on nodes to go to other maps. All very, very nice.

Except, now QT is now being put out to pasture, and the tools to create the VRs are hard to come by.
