Heading defines which direction the panorama is pointing to, when it's initially loaded. You can set the heading to point in any direction for each of your posts.
The user can use the mouse or tap with his fingers to look around and change the orientation of course. But at any moment they can click on the 'radar' icon in the top/right and the panorama will go back to it's original heading.
When you are working in the virtual tour editor, you can adjust the Heading of your panorama in three ways, illustared above:
- Click & drag the heading icon within the image to reposition the heading.
- Manually enter the latitude and logitude values.
- Use one of the preset values as explained below.
- Current sets the heading in the direction the panorama is facing at the moment. Best way to use it is to rotate the panorama in the desired direction first, then click this button.
- Initial same effect as manually setting latitude and longitude to 0. This typically reflects the direction the cameras front lens was facing when the shot was taken. If you look at the flattened panorama before uploading it, the default heading will be pointing to the spot right in the center of the image.
- North sets the direction pointing north (in the geographical sense) based on GPS data found in EXIF. It the uploaded photo file did not contain this information, that option is greyed out. Please note that this value is not 100% reliable because of possible magnetic interference issues.
After you adjust the position of the heading, simply hit SAVE to apply the changes.
Heading can be changed at any time and multiple times over - it doesn't have any lasting consequences for the post or tour, so do not be afraid to experiment and move it around.
If you are building a tour and would like to make use of the backlinks feature, it's recommended to align all the photos in the same direction. More info can be found in this tutorial.
As soon as you save, you can refresh the page and you'll see that after loading, the photo points in the direction you selected.
Default heading in Preferences
In the Perferences section, you can choose how the system will set the heading for all new uploads:
If Set heading to GPS north is selected, the system will look for the heading information in the EXIF meta data in the file. If it is found, the heading will be set in this direction.
If this setting is not selected or the heading information is not present in EXIF, the heading will default to the direction in which the camera was facing during shoot. If you are stitching or rendering your panoramas, the default heading will point to the middle of the image.
The EXIF heading is supposed to point to the physical/geographical north, but it is not always precise. For various reasons like magnetic interference or compass calibration, this value can be off.
Heading & Walkthrough mode
Walkthrough mode can override your heading settings for individual posts. When moving between posts via hotspots, the initial orientation will be cdynamically calculated based from the hotspot position, regardless of where you set your heading to.
It is a very powerful feature and can be used to greatly improve user immersion, but if you want have complete control over the heading when moving from post to post, you'll need to turn off the Walkthrough mode. You can learn all about Walkthrough in this article.
