You will now see a reconstruction of the site.

Navigation
----------

The mouse can be used to navigate in the 3d view. By default, the following controls are enabled:

* **left mouse button**: rotate around a point
* **right mouse button**: pan (move) the scenery
* **center button**: approach and step back

You can reset the point around which rotation and approach is performed by double clicking with the left mouse button on a scenario point.

See :ref:`user_interface_navigation_buttons` for other navigation possibilities. 

-------------------------
Controlling Visualization
-------------------------

You can set visual parameters in the settings box.

By clicking button 1 in the figure below, you can then click a point in the scenery and see a high resolution 2D photograph of the area.

These images can be zoomed using the mouse wheel.

-----------------------------------
Reconstruction comparison
-----------------------------------

You can compare the reconstruction conditions and, for example, quickly measure volume changes. 

#. select the first building state (on the left pane).
#. click on "Pin" (bottom right).
#. Select the second building state (in this example after completion of the excavation). The two point clouds will appear superimposed.
#. Define an area (for example, landfill hills or the excavation pit) with the area definition button on the right pane (marked "4" in the figure)
#. Compute the volume (figures in the picture in :math:`\text{m}^3`, green is the landfill, red is the excavation).

Also, by choosing the "Color" dropdown menu in the "Pointcloud" settings box you can force a fixed color for a particular reconstruction to aid visual inspection.
