Panotour - Panorama Properties - Projection 180

Projection tab

Input field of view
Specifies the selected panorama's angular view and to change it if needed. The 3D lets you see the changes to these values.

  • Horizontal: Sets the horizontal angular surface surrounded by the panorama. This value can be changed.
  • Vertical: Sets the vertical angular surface surrounded by the panorama. This value can be changed.
  • Vertical offset: Sets the panorama's horizon. Shifts the panorama up or down the sphere based on the respective positive and negative values.

An Autopano panorama (Pro or Giga) contains EXIF data in its assembly.
This data sets the angular fields and is reinterpreted by Panotour Pro.
So, the angular fields are kept (they are identical to those of the original panorama).

When a panorama does not contain EXIF data, the angular fields are calculated based on one of 2 values (horizontal or vertical, depending on the image's ratio).
This calculation is applied to the following cases:

  • If the panorama uses an assembly software that is different from Autopano.
  • If the panorama has been changed between when it was created with Autopano and imported into Panotour.
  • If the panorama was exported with Autopano in a format that does not issue EXIF data (i.e. .png).

In these cases, a [!] icon (beside the horizontal and vertical fields) indicates that no EXIF data was found.
The panorama viewed in the center window also has a Warning icon icon showing the same information.
This quickly lets us know what angular fields need to be verified and/or changed.
Changes to these fields will erase the indication icons.

Output projection
This lets us choose the type of projection used to display the panorama in the tour.

  • Display a spherical projection: (default) The panorama is shown in a sphere. This creates the feeling of 3D immersion.
  • Display a planar projection: The panorama is projected onto a plan. This type of projection is particularly suitable for panoramas with small fields of view.
