| Cylindrical
& Spherical Panoramas |
|
|
Cylinder
pans create an experience for the viewer like they are
inside a cylinder. The image is centered on the
horizontal
axis and captures 42 to 45 degrees above and below the horizontal
plane. |
|
|
Spherical
pans, on the other hand, appear to the viewer
to be taken from the perspective of the interior of a
sphere.
The user can look up and down as well as right and left. |

| How
the cursors work |
 |
When a cylindrical
pan displays this cursor, you can hold down the left mouse-button
and drag the image up & down, as well as right and left.
This type of cursor function is always available in the spherical
pans even though the cursor is not displayed. |
 |
Most of the
cylindrical pans have a floor plan or site plan associated with
them. When you place the cursor in the active area of the
floor plan (in 360° pans, the entire floor
plan is active. In pans less then 360°, the active area is
the sweep of the view cone.) the user can left click to instantly
re-orient the view to the direction indicated or hold down the
left mouse button and drag the image right or left. |
 |
If you place the
cursor in the scrolling image of a cylindrical pan , those
panoramas that have the zoom feature activated will see a white
bar with a green dot on the left side of the bar. Placing
the cursor on the bar brings up this pointing-finger cursor.
Hold down the left mouse button and you can zoom in or out of the
image as you drag the pointing finger along the bar. |
 |
This, of course,
means you should wait for the current operation to be completed
before you try to do anything else. |
