8.1. Navigation in the 3D model
There are currently two navigation methods implemented in TWINSPECT®.
SHIFT: In all modes, the movement and zooming speed is faster when pressing SHIFT.
This is the standard navigation mode. In this mode the point of view will be orbiting around the Pivot Point which is defined by the middle of the screen. If the Annotation Panel is activated, it is possible to measure distances, set tags and mark areas in orbital mode.
- Left click and hold and move mouse → rotate around the Pivot Point
- Right click and hold and move mouse → move the Pivot Point
- Mousewheel → Zoom towards to or away from Pivot Point (maximum Zoom is the Pivot Point)
- Double left click → The perspective will zoom in and center the spot, if available and active, matching photos will be shown at the top in the Photo Panel
- Q: move down
- E: move up
- W, Arrow Up: moving forwards
- A, Arrow Left: moving left
- S, Arrow Down: moving backwards
- D, Arrow Right: moving right
8.2. First Person Mode
First Person Mode is an alternative navigation method. If activated via the button in the Toolbar, the mouse is no longer represented by a cursor but will reflect the users perspective directly. Therefore, it is not possible to annotate in first person mode, as there is no mouse cursor available.
Keyboard Navigation
- Q: move down
- E: move up
- W, Arrow Up: moving forwards
- A, Arrow Left: moving left
- S, Arrow Down: moving backwards
- D, Arrow Right: moving right
Press ESC to return to the default navigation mode (orbital navigation).
8.3. Annotation & Measurement
Annotations are made on photographs in the Photo Panel. Measurements and markings are made directly on the 3D model in the 3D panel. Both annotation forms are managed in the Annotation Panel and enriched e.g. with metadata. However, currently only (photo) annotations are output in reports, since reports do not
It is only possible to add measurements and markings to the 3D model in orbital mode.
8.4. Annotation & Measurement Toolbar
The tools for measuring and marking locations, distances and surfaces in the 3D model are organized in the floating toolbar, which can be placed freely in the browser window. If a tool is selected via left click, the mouse cursor will have a colored marker indicating whether the location is not part of the 3D model (red) or is valid for tagging or measuring (green).
When this button is selected, the next left-click in the 3D model marks the corresponding location with a tag. The tag is labeled with a question mark until the tag is described with a title in the Annotation Panel. Afterwards, the first letter of the title is the tag label. The label itself can be moved by drag and drop.
When this button is selected, the next left-click in the 3D model sets the first of two points for a line. The next left-click has to be on the 3D model as well, the distance between both points is shown below the model.
When this button is selected, the next left-click in the 3D model sets the first of several points for a path. The next left-click has to be on the 3D model as well, the distance between the last and the next point is shown in the footer below. In order to finish the path, perform a double left click.
When this button is selected, the next left-click in the 3D model sets the first of several points for an area. The next left-click has to be on the 3D model as well, the distance between the last and the next point is shown in the footer below. In order to finish the area, perform a double left click, the finishing line will be drawn between the first and the last point.
After you have created a Distance, Path or Area annotation the line/area can be running through the 3D model. By clicking on the icon “Bring to the front” the line/area will be recalibrated to be on top of the mesh model and reverse.
8.4. Project, model and configuration
Public or intern models can be opened by the open project dialog in the toolbar.
There are various ways to configure the 3D model and its visualization, e.g. hide and show of a skybox, a grid, a ground, axes, the visualization of the 3D model as point cloud or wireframe etc.
- The project tree dialog in the toolbar
- The menu
- The textures and resolutions dialog in the titlebar.
