 The given example import a XYZ file, which only contains Points. So the graph created is of the structure:

-If you import a PLY file that include both Vertexes and Faces (and/or Lines), GroIMP will create two (or three) point cloud nodes, one per type of object to import from the PLY file.

 Similarly to the point cloud as array, the cloud nodes can be accessed with RGG commands:
 <code java>
-import de.grogra.pointcloud.groimp.PointCloud;
 [pc:PointCloud ::> println(pc.getCloud()); ] // print the CloudGraph node for each point cloud (2 here)
 [pc:PointCloud ::> println(pc.getCloud().pointsToFloat()); ] // print the float array representation of all nodes (in this example it print two float array that contains the same values

 There are three possible export commands:
-  * Export all in one: All the point clouds in the scene are exported into one file. The user needs to select one file in the GUI prompt.
