-====== Add View ======+====== Add, Move, Change View ====== 
 + 
 +===== View Modes ===== 
 + 
 +The available View Modes depend on the loaded Resources: 
 + 
 +  * 3D View 
 +  * Streetlevel Spherical View 
 +  * Streetlevel Planar View 
 +  * Aerial Planar View 
 +  * Aerial Oblique Planar View 
 + 
 +===== Add View ======
  
 Click on the '+' icon and view mode on the left sidebar to open a new view. Next, click on the [[dev:viewer:viewmodes:reference|Reference View]] or an existing View on the location where a new View should be opened. \\ Click on the '+' icon and view mode on the left sidebar to open a new view.

-===== Find Best Photo ======+===== Move View ===== 
 + 
 +Move an existing View to a new location 
 + 
 +Hover over the ID of the View on top, click 'move' and choose another location in one of the Views or Reference View. For image Views, it's possible to choose a specific image by clicking on the footprint of the photo position itself. 
 + 
 +To move all views at once, hold Shift in move mode and choose a new location. While holding Shift, 'move' in the View Action Fly-out will change to 'move all' to indicate this. 
 + 
 +===== Switch View Mode ===== 
 + 
 +Change the View Mode of a View.
  
-==== Input Parameters ====+Hover over the eye-icon on top of the view to open the 'View Mode Fly-out' and choose the desired View mode to change the type of the existing View.
  
-FIXME Add find photo algorithm information+===== Focus other Views =====
  
-Inputs:  
-  * focusPosition : The position we are finding a suitable photo for. 
-  * viewPosition : The position from where we are observing the focus position. 
-  * minPhotos : The minimum amount of photos to find after applying the requireFocusVisible filter. Ignored if not positive. 
-  * minDistance2D : The minimum 2D distance of photo's to the search position (metric). Used when searching for streetlevel photo's.  Ignored if not positive.  
-  * relevantPhotosMax : The maximum number of relevant photos to return. 
-  * searchDistances2D : The array of search distances to use when finding a closest photo. 
-  * findCloserPhotoAlgorithm : The algorithm to sort results and find a closest photo. 
-    * PIXEL_DISTANCE : Identifies the technique to find a closest photo by projecting the search coordinate on the photo and then sorting by distance to the photo center. 
-    * SPATIAL_DISTANCE : Identifies the technique to find a closest photo by taking the 3d distance to the view position (fall back on focus position). 
-  * requireFocusVisible : For planars, only return photo's that have the search position inside the photo? (false to disable) 
-  * isStreetlevel :  We are searching on streetlevel?  
-    * If true the 'is focus visible?' check (enabled by requireFocusVisible) will check whether the focus position is in view 
-    * for each photo by looking at the angular distance between the photo heading (pan) and the heading defined by the vector from photo position to focus position. 
-    * This yields a better result for streetlevel planars (sphericals don't have a 'focus visible' check). 
-  * searchCenter : Identifies searching around the view position. 
-    * FOCUS : Identifies searching around the focus position and selecting the photo closest to the focus position. 
-    * FOCUS_AND_VIEW :  Identifies searching around the focus position and selecting the photo closest to the view position if provided (focus position as fallback).  
-    * VIEW : Identifies searching around the view position and selecting the photo closest to the view position. 
  
-There are other input parameters, but they do not apply to how the algorithm functions.+===== Search & Open best photo =====
  
-Some constants : +Add, Move and Focus Views trigger the request to Search and Open the "best" image. \\ 
 +Depending on the use case and data-type other methods or configurations can be used.  \\ 
 +Anyway, the action consists of 2 consecutive steps 
 +  - Get Candidates 
 +  - Sort Photos
  
-  * AerialDistances ''25,50,100,200,400,800,1600,3200,6400,12800'' +==== Get Candidates ====
-  * StreetlevelDistances ''3,9,27,81,243,729''+
  
-Default parameter values : +Find relevant photos around the requested Focus Coordinate. \\ 
 +Any photo becomes a candidate if  
 +  * Focus Coordinate is nearby the Photo Coordinate (Search Radius)  
 +  * Focus Coordinate is in the field of View of the Photo.
  
-^ ^ Streetlevel Spherical ^ Streetlevel Planar ^ UAV Planar ^ Oblique Planar ^  +Searching for candidates is done by incrementally increasing the search radius and ends when 
-| focusPosition       | <required> | <required> | <required> | <required>+  10 or more candidates are found, or 
-| viewPosition        | <optional> | <optional> | <optional> | <optional>+  * the maximum search radius is reached.
-| minPhotos           | 0 | 0 | 3 | 0 | +
-| minDistance2D       | 0 | 0 | 0 | 0 | +

-<sup>1</sup> Configurable via ''Views -> (Type) Image View -> Open best planar photo by''\\  +==== Sort Photos ====
-<sup>2</sup> Configurable via ''Views -> Image Views -> Open image from 3D View''+
  
-==== Algorithm ====+Sort candidates by relevance, to get the best image and order alternative images. \\ 
 +The best image has the smallest value for the selected option
  
 +Options:
 +  * By Direction offset \\ Offset between the Candidate Direction (Candidate to Focus Coordinate) and Request Direction (3D View Position to Focus Coordinate).
 +  * By Pixel offset \\ Pixel offset of the Focus Coordinate projected on the Candidate Image to the Candidate Image Center.
 +  * By Spatial distance \\ Spatial distance of the Focus Coordinate to the Candidate Coordinate.
