I need to get the following behavior.
I have a list of points with x,y, and z coordinates and radius. I want to use a vtkKochanekSpline and vtkTubeFilter with the SetVaryRadiusToVaryRadiusByAbsoluteScalar option.
I checked this example https://kitware.github.io/vtk-examples/site/Cxx/VisualizationAlgorithms/TubesFromSplines/, but it uses just two values. My issue is to calculate the t value.
Any help on this @LucasGandel ?
