See here to see how install plugins in GroIMP.

All features in this overview are available when a 3D project or an RGG project is opened in GroIMP. The functions work independently from XL scripts and are only based on the objects that are currently available in the 3D view. text/html 2025-12-10T12:14:12+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=02_user_tutorials:pointclouds:03_point-cloud-tools-in-xl-and-headless-mode&rev=1765368852&do=diff Point Cloud Tools in XL and Headless Mode Note: This tutorial is based on the plugin “PointCloud” that you can get either through the Plugin manager (within Groimp) or by downloading the jar here. This overview contains the list of available java functions concerning point cloud import, clustering, splitting, merging, and export. They can be used in the java code (by future developers) and in XL code (by GroIMP users). They can also be used in headless mode.

In the following, the point cloud (shown in the figure below) has been artificially created and therefore fits the tree very well. text/html 2025-12-12T10:51:09+00:00 Anonymous (anonymous@undisclosed.example.com) https://dokuwiki.grogra.de/doku.php?id=02_user_tutorials:pointclouds:point-cloud-tools-algorithms-and-math&rev=1765536669&do=diff Point Cloud Tools: Algorithms and Math Note: This is based on the plugins “PointCloud” and “PointCloud-Shapefitting” you get them through the Plugin manager. Because formulas can not be displayed here efficiently, we would recommend to read the belonging practical reports for more information about the math behind the point cloud features.
