| + | * Streetlevel Planar View | ||

| - | ==== Input Parameters ==== | + | Hover over the eye-icon on top of the view to open the 'View Mode Fly-out' |
| - | 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' | ||
| - | * 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' | ||
| - | * isStreetlevel : We are searching on streetlevel? | ||
| - | * If true the 'is focus visible?' | ||
| - | * 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' | ||
| - | * 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 " |
| + | 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 | + | ==== Get Candidates ==== |
| - | * StreetlevelDistances | + | |
| - | 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. | ||

| + | 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. | ||
