Hi All,

 

I am plotting a 3d plot using 42 points and now I want to do pick operation
on this curve. I use vtkPointPicker class. I say getPointId

Then getDataSet and using this point id I extract the data point I want. 

My problem is the getPointId method always returns the same number
(239306080) no matter where I pick in the curve and obviously this number is
wrong.

I assume the point id should be between 0-42?. 

 

Is there something I am missing in the set up?. Or Is what I am expecting
wrong?. 

How do I get the pointed correctly?.

 

Thank You in advance for your help

Regards

Gowri
