FoV stands for ''Field Of View''. This parameter basically indicates how much a panorama can be zoomed in and out.FoV will have maximum and minimum limits. It is often important to set the limits correctly as the panoramic image looks distorted when viewed at extreme FoV.
Tilt is the vertical angle of the viewer relative to the center of panorama. This parameter can also be set to have two limits: top and bottom. If I want to cover the top part of the panorama, a sealing for instance, I will set the top limit to lower than 90'.
Pan is the horizontal angle of the viewer relative to the center of panorama. This parameter can also be set to have two limits: right and left. It works very similar to the Tilt parameter except this one controls panorama''s horizontal movements whereas the tilt controls vertical movements of the panorama.
GUI stands for Graphical User Interface. This usually is represented as a system of buttons and other such elements by pressing which the viewer can control the panorama. Common features that can be controlled by GUI include: zooming in & out, going full screen mode and back to frame, jumping between different viewers, playing embedded sounds, movies, images, etc. GUI can be quite complex. It's design should also nicely suit the overall design of the web-page the panorama is played on.
Hot Spot is a small mark that appears inside the panorama. It usually has a shape of an arrow that points out in the direction where the next viewer is located. Left-click on the hot spot switches the viewer to the next one. The 1st sample virtual tour has got only one viewer (individual panorama). So, it does not need any hot spots. However, the 2nd one has got two viewers that are connected with each other with the hot spots in the form of small reddish arrows. |
