Focus and Synchronize Views
Concepts
The Focus and Synchronize Views functions allow views to sync up to the focus position of other views.
- A focus position can be derived from a view, based on render mode and state.
- A focus position can also be applied to a view. How this happens, also differs per render mode.
Focus Action
The “Focus” View Action lets all other views focus on the data that is visible in the focused view. A focus position is derived from the focused view and then applied to all other view in the workspace.
The Focus action can be enabled in Viewer and View Settings.
Synchronize Views
Views can also be configured to automatically synchronize to the active view. In the Navigation Settings 3 synchronization types are available :
- Synchronize Views : Non-reference views sync with interactions on other non-reference views.
- Synchronize Views From Reference : Non-reference views sync with interactions on the reference view.
- Synchronize Reference From Views : The reference view syncs with interactions on non-reference views.
When any of these settings are enabled, synchronization occurs automatically. Some views may synchronize in real-time, while others may react with a small delay (500ms) because updating in real-time is not necessary or feasible.
Derive a Focus Position
| View Mode | Origin |
|---|---|
| 2D Reference | Get 2D center position. |
| 3D | Get 3D center intersection with visible data |
| Spherical Photo | Get 3D photo position |
| Planar Photo | - Ground footprint possible : Get 3D center intersection with visible data, DEM or plane at ground height. - No ground footprint : Get 3D photo position |
When possible, a view position is also retained, so the pan/tilt angle can be retained when applying the focus position.
Apply a Focus Position
If the focus position is 2D, the focus position is made into a 3D position by inserting with the workspace terrain model or the ground plane.
| View Mode | Technique |
|---|---|
| 2D Reference | Move to focus position (x,y) |
| 3D | Move to a position that looks at the focus position from a distance (max 100 meters). Copy the pan/tilt angles when possible. |
| Spherical Photo | Open the best photo for this position and focus - A 3D focus position will change pan/tilt. - A 2D position will only change pan |
| Planar Photo | Open the best photo for this position and focus. |
See Add, Move, Change View for more information on photo search.
Exceptions
There are some cases where view synchronization is not just deriving a focus position and applying it.
3D to 3D
In this case, the target 3D view will mimic the source view.
Spherical Photo to 3D
In this case, the 3D view will mimic the source view.
3D to Photo
In this case, the centre of the 3D view is used as a focus position for the photo view.
