I am sending this email to make a modest offer to the OpenJUMP developer community.
I’ve written a Java library for processing Delaunay triangulations that may be useful for OpenJUMP. The Tinfour open-source software API is sufficiently fast to handle large unstructured data sets such as Lidar. I did a little testing this morning and was able to process a Lidar file containing 15 million samples in 12 seconds. I think that the API could be used as part of an OpenJUMP plugin. If you would like to learn more, you may visit the Tinfour project at https://github.com/gwlucastrig/Tinfour Due to my job commitments, I do not have the availability to write a plugin myself (thus the “modest” in this offer). But if someone were interested, I would be willing to support the effort by answering questions, assisting in design issues, and implementing Tinfour improvements or customizations required for the plugin. Finally, if you would like to explore the feasibility of using Tinfour to process Lidar, I have a couple of demonstration applications that are available as part of the Tinfour distribution. The Tinfour Viewer allows you to drag and drop a Lidar file onto a display area and review it interactively. The demonstrator should be enough to test the idea and reveal any issues I may not have thought of. Thank you for your time and attention. I wish the OpenJUMP community the best of success with your project. Gary
