Getting started : upload a panorama
22
-----------------------------------
23

    
24
1. Go to the index and click "Ajouter un panorama", let upload process
25
2. Just click on the image in the subsequent list, and wait for it to be
26
   processed (split into tiles) ;
27
3. Choose "accéder directement au panorama" to view it and use the red up-right box to enter
28
   coordinates and altitudes from where the photos have beenn taken. *bouclage*
29
   means that left and right borders are matching exactly (360° panorama).
30
4. Reference some known points by right clicking (see relevant section), the
31
   others will get interpolated and presented to you on the view.
32

Viewing reference points
35
------------------------
36

    
37
You'll see big colored bubbles :
38

    
39
* *Blue points* : reference points you referenced and pointed by hand
40
* *Red points*  : other panorama (click and fly to it !)
41
* *Green points* : reference points automatically placed (estimated according to
42
   the blue ones)
43

    
44

    
45
Adding reference points
46
----------------------------
47

    
48
Reference points are known points you are likely to see from your panoramas,
49
they are a visual reference and a way to orientate your panoramas.
50

    
51
By default, there are no *ref_points*, you can create your own *ref_points* list
52
or use one of the provided lists.
53

    
54
To get started, copy one of the files from `ref_points` folder in the root
55
folder, remane it to `ref_points.local.php` and customize it.
56

    
57
*Hint: prefer to register the altitudes of the topmost point of a building: they
58
 are the easier parts to aim from other panoramas.*
