Hi Fred, My name is Tim Hutton, apologies for the lack of identification in the previous post (it was my first message to this list). My email and details are below this time.
In VTK (the visualization toolkit) there is the option of using the r2logr kernel or the r kernel, since the class does both 2D and 3D TPS. I presume this is what you are referring to. In 3D the r kernel should be used, in 2D the r2logr kernel, right? (This comes directly from your work, and from what you've said when I asked a question at one of your talks at UCL.) Thus I don't think there is an error - if there is really a problem with the code then please let us know! The code was developed by David Gobbi and myself and others. I think other people are experimenting with other kernels, so VTK also has the option of defining your own. I should point out to everyone that the $10 million is only a rough estimate of what VTK would cost to commercially re-develop. It is an open-source system, and so available for free. http://www.visualizationtoolkit.org Tim.
