Detailed Description

Streamline generator.

vtkGenericStreamTracer is a filter that integrates a vector field to generate streamlines. The integration is performed using the provided integrator. The default is second order Runge-Kutta.

vtkGenericStreamTracer generate polylines as output. Each cell (polyline) corresponds to one streamline. The values associated with each streamline are stored in the cell data whereas the values associated with points are stored in point data.

Note that vtkGenericStreamTracer can integrate both forward and backward. The length of the streamline is controlled by specifying either a maximum value in the units of length, cell length or elapsed time (the elapsed time is the time each particle would have traveled if flow were steady). Otherwise, the integration terminates after exiting the dataset or if the particle speed is reduced to a value less than the terminal speed or when a maximum number of steps is reached. The reason for the termination is stored in a cell array named ReasonForTermination.

The quality of integration can be controlled by setting integration step (InitialIntegrationStep) and in the case of adaptive solvers the maximum error, the minimum integration step and the maximum integration step. All of these can have units of length, cell length or elapsed time.

The integration time, vorticity, rotation and angular velocity are stored in point arrays named "IntegrationTime", "Vorticity", "Rotation" and "AngularVelocity" respectively (vorticity, rotation and angular velocity are computed only when ComputeVorticity is on). All point attributes in the source data set are interpolated on the new streamline points.

vtkGenericStreamTracer integrates through any type of dataset. As a result, if the dataset contains 2D cells such as polygons or triangles, the integration is constrained to lie on the surface defined by the 2D cells.

The starting point of traces may be defined in two different ways. Starting from global x-y-z "position" allows you to start a single trace at a specified x-y-z coordinate. If you specify a source object, a trace will be generated for each point in the source that is inside the dataset.
