## Introduction vtkImageStreamline - integrate streamlines in a vtkImageData vtkImageStreamline is a filter that generates streamlines from a vtkImageData input over which a vector field is defined. This filter will look for vectors (i.e. getVectors()) in the input. It will then integrate these vectors, using Runge-Kutta 2, from a starting set of seeds defined by the points of the 2nd input until a specified maximum number of steps is reached or until the streamline leaves the domain. The output will be a vtkPolyData which contains a polyline for each streamline. Currently, this filter does not interpolate any input fields to the points of the streamline. ## Public API ### integrationStep Set/Get the step length (delT) used during integration. ### maximumNumberOfSteps Set/Get the number of steps to be used in the integration. Integration can terminal earlier if the streamline leaves the domain.
