vtkSpline

1.5
vtkSplineFilter is a filter that generates an output polylines from an input set of polylines. The polylines are uniformly subdivided and produced with the help of a vtkSpline class that the user can specify (by default a vtkCardinalSpline is used). The number of subdivisions of the line can be controlled in several ways. The user can either specify the number of subdivisions or a length of each subdivision can be provided (and the class will figure out how many subdivisions is required over the whole polyline). The maximum number of subdivisions can also be set.
The output of this filter is a polyline per input polyline (or line). New points and texture coordinates are created. Point data is interpolated and cell data passed on. Any polylines with less than two points, or who have coincident points, are ignored.
