Hi Erik, thanks for your comment. In reality, the colors of the interpolations are the result of Alberto de Luca's work to have a good style system for rasters. I just added some LUTs with more colors to make the rasters more aesthetically beautiful, "Juicy" as you wrote ;-)
I am interested in your proposal regarding the TSP code. It could be a great integration to the interpolation plugin. Let me know where you will put your code. Of course I will extend the copyright to thank your cooperation. I will move all the stuff on GitHub later. This plugin was born as a test to recover useful code of projects destined to be abandoned. John Lindsey, the author of the excellent WhiteBox GAT GIS for raster in java, wrote to me days ago that he considers his project to be legacy and is not interested in renewing it. In fact Whitebox Gat no longer works with the new javas. Kosmo and AdbToolbox, interesting clones of OpenJUMP, are practically abandoned. I have worked with these software for years and I feel I need to recover at least some of their functionality on OpenJUMP. Since the raster management material is large, I will probably have work for years.
