[vtkusers] C++ to Java mapping guide?

[Gerrick Bivins]

Hi Graham,
Did you take a look at this example:
http://vtk.org/gitweb?p=VTK.git;a=blob;f=Examples/Statistics/ExampleKMeansStatistics.cxx

At first glance, it seems more complete than the one on the wiki. I haven't used that filter but
it's at least another reference for you.

I've done quite a bit with VTK in native and wrapped languages and found that most of it is 1-to-1.
The limitations I've found are usually due to wrapping restrictions based on incompatibility in the languages.
And even in those cases, there is usually a way around it (I'm looking at you vtkAlgorithm::SetInputArrayToProcess :) )

Lots of people are using VTK in Java and other wrapped languages as well so if you have questions just post to the list and
someone will be glad to point you in the right direction.

Hi

Working through the KMeansClustering C++ example, it is difficult to convert the code from C++ to Java.

Another problem I found is the line:


vtkVariant v = kMeansStatistics->GetOutput()->GetValue(r,kMeansStatistics->GetOutput()->GetNumberOfColumns() - 1);





In Java the GetOutput() method returns an object of type vtkTable, which does not support the GetValue() method?



It does support the GetRow() method which returns an object of type vtkVariantArray but can't see an easy way to get values out of the variant array.



I must say that trying to get these simple examples is proving very difficult, and can only imagine how difficult it must be for real life examples.



Thanks.
