Hotspots are points or areas of interaction within the panorama. They can open other panoramas, open websites, and pop up information boxes, images, and videos.
After loading an image into Pano2VR or opening an existing project, you can then enable the point or polygon hotspot modes in the Viewer.
If you want custom hotspot images or just points of interaction, you would add point hotspots.
If you want to draw an area of interactivity, you would add polygon hotspots.
