#Documentation # @brief Interactively add points # # As in Step4, load one or more data sets (many image, # surface and other formats) and create 3 views on the data. # Additionally, we want to interactively add points. A node containing # a PointSet as data is added to the data tree and a PointSetDataInteractor # is associated with the node, which handles the interaction. The # @em interaction @e

//## may be "empty point set") and associated @a actions (e.g., add a point
//## at the position where the mouse-click occurred).
