Hi Sebastien, I've implemented and tested a fix to the problem you discovered with your interpolation testing - sorry for the delay. Herein you'll find two attachments: Irregular3DSet.jar, dataFit.jar. Apply jar xvf to the first of these in your visad directory. Jar xvf the second in the top level of your classpath; note that this jar file contains my modifications of the source you were kind enough to provide. It will display the dataset, as well as, any NaN points which will be blue. You should see the blue (NaN interpolants) outside the hull of your dataset. Let me know if have any problems, TomR
