I would like to get something similar to this example (but it is not properly working yet):
http://www.360vista.eu/bittest/bittest.html
There is a number of hotspots in a bunch of panoramas.
Each hotspot opens a specific info-panel and also visualizes a static button next to this panel.
This button is supposed to open more detailed and as well specific info web page externally (in a new tab).
So I need each hotspot to be able to reset the button to load different web page, specific to only this triggering hotspot.
The next hotspot should reset the button to open another info web page.
The button has to get invisible/disabled together with the info-panel at any user interaction.
The hotspots are linked to the sphere of each pano they belong to while the button is statically linked to the screen, next to the info-panel.
All this turned to be way more complicated than what my very limited experience could help me to successfully resolve.
