Addon sub-menu consists of commands that call custom functions in TerraScan. New commands and functions can be added to TerraScan using a custom DLL.
An example is provided by the View histogram function which opens the Laser intensity histogram window. It displays the distribution of intensity values of all loaded points or of selected classes or scanners. The window also shows the average, median, and spread values of the points that are in the selected class and captured by the selected scanner.
See Chapter DLL Interface for more information about custom DLLs in TerraScan.
