-====== 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.

 +===== 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.
 +
 +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.
 +
 +===== Focus other Views =====
 +
 +
 +===== Search & Open best photo =====
  
-===== Find Best Photo ======+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
  
-FIXME Add find photo algorithm information+==== Get Candidates ====
  
-Parameters :  +Find relevant photos around the requested Focus Coordinate. \\ 
-  * viewPosition : The position of the viewer (optional). +Any photo becomes a candidate if  
-  * returnSphericals : Return spherical photo positions? +  * Focus Coordinate is nearby the Photo Coordinate (Search Radius)  
-  * returnPlanars : Return planar photo positions? +  * Focus Coordinate is in the field of View of the Photo.
-  * 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 use to 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). +
-  * directionFilter : Only return photo's in a specific direction? (null to disable) +
-  * tagFilter : Only return photo's from resources that match the given tag filter? (null to disable) +
-  * timeFilter : Only return photo's from resources that match the given time filter? (null to disable) +
-  * 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). +
-  * tagFilterApplyOnResourceGroupChildren : If tagFilter is specified, this parameter determines whether in case of a resource group, it applies to the children only. false means it applies to the parent resource only. +
-  * timeFilterApplyOnResourceGroupChildren : If timeFilter is specified, this parameter determines whether in case of a resource group, it applies to the children only. false means it applies to the parent resource only. +
-  * 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.+
  
-  * AerialDistances = ''25,50,100,200,400,800,1600,3200,6400,12800'' +Searching for candidates is done by incrementally increasing the search radius and ends when 
-  * StreetlevelDistances = ''3,9,27,81,243,729''+  * 10 or more candidates are found, or 
 +  * the maximum search radius is reached.
  
 +==== Sort Photos ====
  
 +Sort candidates by relevance, to get the best image and order alternative images. \\
 +The best image has the smallest value for the selected option
