3D Viewer
The 3D viewer allows the inspection the coarse point cloud (Coarse Reconstruction) and the finally generated 3D model (Dense Reconstruction). In addition, the viewer serves for outlining the ROI and for the localization of GCP positions required for Standard as well as for Constrained Referencing.
By pressing F1 on the keyboard tooltips for navigation as well as for editing annotations are available in the 3D viewer. The tooltips may differ in respect to the active item.
Toolbar of the 3D Viewer
3D View Options 
- Move to Home Position
- Sets the viewer to its initial position - View All
- Zooms out from the current view. Zooms to the previous view again - Top Down View
- Orientates the 3D model from the camera view (top down) - Auto Rotate (fixed or view)
- Rotates the 3D model from a fixed point (top down) or from the current point of view - Projection type
- Toggles between perspective and orthographic projection - Fullscreen
- Switches between the fullscreen display and the windowed display
Mesh Draw Mode 
- Draw as is - The 3D topography is completely overlaid by the digital photograph
- Wireframe
- A triangulated red coloured point cloud is forming the topography - Wireframe Overlay
- The 3D model and a red coloured overlay of the wireframe is forming the topography - Points
- The point cloud of the scene shown - Show Texture - Displays the 3D model with texture in the viewer (shortcut key “Ctrl” T)
Navigation
Mouse navigation
- Pan View
- The middle mouse button is used to pan the 3D model - Rotate View
- The right mouse button rotates the 3D model. Just keep the right button pressed and move the mouse around to see the 3D model rotating. - Zoom View
- When turning the wheel of a mouse the 3D model is zoomed - Center View on Position
- Centers to the current position - Center and Zoom
- Pressing “Alt” and turn the mouse wheel centers the and zoom to the current position
Keyboard navigation
- Straight motion is performed by pressing the corresponding arrow key “Left”, “Right”, “Up” or “Down”.
- Zooming is performed by pressing “Ctrl” simultaneously with the arrow key “Up” for zooming in and the arrow key “Down” for zooming out.
- Rotation of the 3D model in a desired direction is performed with the corresponding arrow key “Left”, “Right”, “Up” or “Down”.
It is preferred to have a mouse with 3 buttons, or a wheel mouse. Usually the wheel acts as the third mouse button.
