Detailed Description

generate uniformly subdivided polylines from a set of input polyline using a vtkSpline

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.

◆ SetTextureLength()

virtual void vtkSplineFilter::SetTextureLength ( double  )
virtual

Control the conversion of units during the texture coordinates calculation.

The TextureLength indicates what length (whether calculated from scalars or length) is mapped to the [0,1) texture space.

◆ RequestData()

int vtkSplineFilter::RequestData ( vtkInformation request,
vtkInformationVector **  inputVector,
vtkInformationVector outputVector 
)
overrideprotectedvirtual

This is called by the superclass.

This is the method you should override.

Reimplemented from vtkPolyDataAlgorithm.
