Panels

There are 4 main panels which give specific information depending on the type of layer viewed:

  • Layers Panel - the panel where the steps of reconstruction are displayed in a list, i.e. photos, point clouds, DEMs, etc.

  • Console Panel - displays the sequence of the Pixpro performed actions in detail.

  • Properties Panel - displays the related information of the step. The type of information depends on the selected option, i.e. if the DEM is selected, the panel gives detailed information on the DEM parameters and definite values, etc.

  • Tools Panel - allows viewing and adjusting Scale and Profile settings. For scaling, it allows setting the scale manually and displays the scaling parameters. For Profile, it displays calculations on surface, slope angle, elevation and distance as well as allows exporting the profile data. It is placed behind the Properties panel and is active only when the Set scaling or Profile options are enabled.

Additionally two more panels can be enabled for different functionality - timeline and profile.

  • Timeline Panel - panel used for timeline calculations to compare volumes in time. Below software interface with the timeline panel enabled.

  • Profile Panel - panel used for displaying the profile. Below software interface with the profile panel enabled.
