Hello,  
I’m writing a program in C# that shows the stress and strain from aircraft on a slab of concrete and would like to label the contours I generate based on those values. I have the contours being drawn correctly but don’t know how to get them labeled. I’m sorry if this is a dumb question, I’ve VERY new to programming using VTK. I found an example on [VTK for Climate Science - Kitware Blog](https://blog.kitware.com/vtk-for-climate-science/) under the heading Labeled Contours and it says to use vtkLabeledContourMapper and vtkLabeledContourPolyDataItem but I haven’t been able to find any examples on how to implement these. I also found an example of how to do what I want but it’s in C++ and the C# vtk ([ActiViz.Net](http://ActiViz.Net)) doesn’t seem to have the same methods. Any help would be appreciated.
