The plugin enables import & export of point cloud from XYZ and PLY file formats. These point clouds can be added in the simulation as graph, where each point is added as terminal vertices to a balanced tree in the project graph. Adding the objects only as terminal vertices enables to keep the concept of local transformation of GroIMP, which enables to manipulate the points individually using turtle geometry and XL commands.
If the imported file also includes meshes or lines, these objects are added as separate trees. The meshes and lines are then linked to their corresponding points using refinement edges. This structure of separated trees with only specific relationships allows to easily manipulate only one scale of the structure while keeping the included knowledge and relationships.
A more in depth description of the point cloud objects in GroIMP is available on the software wiki. The current version 1.8 requires groImp 2.1.5 or higher
