Detailed Description

Evenly spaced streamline generator for 2D.

vtkEvenlySpacedStreamlines2D is a filter that integrates a 2D vector field to generate evenly-spaced streamlines.

We implement the algorithm described in: Jobard, Bruno, and Wilfrid Lefer. "Creating evenly-spaced streamlines of arbitrary density." Visualization in Scientific Computing '97. Springer Vienna, 1997. 43-55. The loop detection is described in: Liu, Zhanping, Robert Moorhead, and Joe Groner. "An advanced evenly-spaced streamline placement algorithm." IEEE Transactions on Visualization and Computer Graphics 12.5 (2006): 965-972.

The integration is performed using a specified integrator, by default Runge-Kutta2.

vtkEvenlySpacedStreamlines2D produces polylines as the output, with each cell (i.e., polyline) representing a streamline. The attribute values associated with each streamline are stored in the cell data, whereas those associated with streamline-points are stored in the point data.

vtkEvenlySpacedStreamlines2D integrates streamlines both forward and backward. The integration for a streamline terminates upon exiting the flow field domain, or if the particle speed is reduced to a value less than a specified terminal speed, if the current streamline gets too close to other streamlines (vtkStreamTracer::FIXED_REASONS_FOR_TERMINATION_COUNT + 1) or if the streamline forms a loop (vtkStreamTracer::FIXED_REASONS_FOR_TERMINATION_COUNT). The specific reason for the termination is stored in a cell array named ReasonForTermination.

Note that normalized vectors are adopted in streamline integration, which achieves high numerical accuracy/smoothness of flow lines that is particularly guaranteed for Runge-Kutta45 with adaptive step size and error control). In support of this feature, the underlying step size is ALWAYS in arc length unit (LENGTH_UNIT) while the 'real' time interval (virtual for steady flows) that a particle actually takes to trave in a single step is obtained by dividing the arc length by the LOCAL speed. The overall elapsed time (i.e., the life span) of the particle is the sum of those individual step-wise time intervals.

The quality of streamline integration can be controlled by setting the initial integration step (InitialIntegrationStep), particularly for Runge-Kutta2 and Runge-Kutta4 (with a fixed step size). We do not support Runge-Kutta45 (with an adaptive step size and error control) because a requirement of the algorithm is that sample points along a streamline be evenly spaced. These steps are in either LENGTH_UNIT or CELL_LENGTH_UNIT.

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

vtkEvenlySpacedStreamlines2D supports integration through any type of 2D dataset.

The starting point, or the so-called 'seed', of the first streamline is set by setting StartPosition
