You can now “fly through” your virtual tour with animated transitions on Kuula.
There are a variety of transitions available. Here is a video showing the different transitions.
You can try out the transitions for free on Kuula, which has both free accounts and pro accounts (But please note that the hotspot alignment option works only for pro accounts). To use the transitions, go to the virtual tour’s settings page with the thumbnails of the photos. Below the description field is a dropdown box where you can select the transition you want.
