There are two API
tools to help client applications interact with the user: |
|
The
SetSelectionFilter method and FilterAction property of PointCloudInstance
allows API users to specify volumetric filter to a cloud. The parts of the
cloud that pass this filter will be rendered differently from the rest of the
cloud, with highlighting done with blue highlight color. |
|
Selection.PickBox()
invokes a two click selection that lets users specify a rectangular area on
the screen. This returned box generates a filter and either highlights or
isolates the selected points in the cloud. |
