Creating Partial Panoramas (Pano2VR)
Partial panorama images have a field of view of less than 360º. They are also called cylindrical panoramas. This article will outline the basic steps in outputting a partial panorama.
The First Steps
- Import your partial panorama.
- If you haven't already done so, choose Select Input from the input section and select Cylinder as the Input Type.
- Enter the angle of the image into the Field of View text box. Choose OK when you are done.
- In the Viewing Parameters section, you can set a default view and the Zoom limits.
- If you like, you can add hotspots and sound to your project.
- Go to the Output section and choose one or more of the following output formats.
Outputting to QuickTime
- Choose QuickTime from the format list and then click Add to open the settings.
- Adjust the QuickTime settings just as with a full panorama.
Just a few things to note:
- Subtiles separate Cylindrical panoramas in vertical pieces for progressive download. For example, if your image is 240º, the default setting would be 24. This means that there are 24 slices that are 10 degrees wide. If you do not need your image to progressively download, set this to 1 to have just one slice and to download all at once.
- Under the Display Settings, there is something called Correction. This gives you the option to disable or enable 3D distortion.
When 3D distortion is disabled, you'll get a flat panoramic image and the 3D effect is lost. If you wish to not have the 3D effect, it may be best to use the Flat image input type instead.
Outputting to Flash
- Choose Flash from the format list in the Output section and click Add to open the settings.
- Adjust the Flash settings like you would for a full panorama.
Something to note:
- If you enable Auto Rotation, the movie will pan to the left or right and once it reaches the edge of the image, it will stop and reverse its rotation.
Outputting a Thumbnail
- Choose Transformation from the format list in the Output section and click Add to open the settings.
- Adjust the Transformation settings as you would for a full panorama.
A few things to note:
- A partial panorama covers only a small portion of a sphere. If you want to extract a part of your image and keep the straight lines, the best option is to choose Rectilinear as the image Type.
- Images that show the empty areas and are saved as PNG or TIFF, will have this area saved as transparent. You can then further modify the image in your editor of choice.
