| override void | AddDataSet (vtkDataSet dataset) |
| Add a dataset coupled with a cell locator (of type vtkAbstractCellLocator) for vector function evaluation. Note the use of a vtkAbstractCellLocator enables robust cell location. If more than one dataset is added, the evaluation point is searched in all until a match is found. THIS FUNCTION DOES NOT CHANGE THE REFERENCE COUNT OF dataset FOR THREAD SAFETY REASONS. | |

| vtkAbstractInterpolatedVelocityField (IntPtr rawCppThis, bool callDisposalMethod, bool strong) | |
| Automatically generated constructor - called from generated code. DO NOT call directly. | |
| void | ClearLastCellId () |
| Set the last cell id to -1 to incur a global cell search for the next point. | |
| virtual int | GetCacheHit () |
| Get the caching statistics. CacheHit refers to the number of level #0 cache hits while CacheMiss is the number of level #0 cache misses. | |
| virtual int | GetCacheMiss () |
| Get the caching statistics. CacheHit refers to the number of level #0 cache hits while CacheMiss is the number of level #0 cache misses. | |
| virtual bool | GetCaching () |
| Set/Get the caching flag. If this flag is turned ON, there are two levels of caching for derived concrete class vtkInterpolatedVelocityField and one level of caching for derived concrete class vtkCellLocatorInterpolatedVelocityField. Otherwise a global cell location is always invoked for evaluating the function values at any point. | |
| virtual int | GetLastCellId () |
| Get/Set the id of the cell cached from last evaluation. | |
| virtual vtkDataSet | GetLastDataSet () |
| Get the most recently visited dataset and it id. The dataset is used for a guess regarding where the next point will be, without searching through all datasets. When setting the last dataset, care is needed as no reference counting or checks are performed. This feature is intended for custom interpolators only that cache datasets independently. | |
| virtual int | GetLastDataSetIndex () |
| Get the most recently visited dataset and it id. The dataset is used for a guess regarding where the next point will be, without searching through all datasets. When setting the last dataset, care is needed as no reference counting or checks are performed. This feature is intended for custom interpolators only that cache datasets independently. | |
| int | GetLastLocalCoordinates (IntPtr pcoords) |
| Get the interpolation weights cached from last evaluation. Return 1 if the cached cell is valid and 0 otherwise. | |
| int | GetLastWeights (IntPtr w) |
| Get the interpolation weights cached from last evaluation. Return 1 if the cached cell is valid and 0 otherwise. | |
| virtual bool | GetNormalizeVector () |
| Set/Get the flag indicating vector post-normalization (following vector interpolation). Vector post-normalization is required to avoid the 'curve-overshooting' problem (caused by high velocity magnitude) that occurs when Cell-Length is used as the step size unit (particularly the Minimum step size unit). Furthermore, it is required by RK45 to achieve, as expected, high numerical accuracy (or high smoothness of flow lines) through adaptive step sizing. Note this operation is performed (when NormalizeVector TRUE) right after vector interpolation such that the differing amount of contribution of each node (of a cell) to the resulting direction of the interpolated vector, due to the possibly significantly-differing velocity magnitude values at the nodes (which is the case with large cells), can be reflected as is. Also note that this flag needs to be turned to FALSE after vtkInitialValueProblemSolver:: ComputeNextStep() as subsequent operations, e.g., vorticity computation, may need non-normalized vectors. | |

| Get/Set the name of a spcified vector array. By default it is NULL, with the active vector array for use. | |
| void | SelectVectors (string fieldName) |
| Get/Set the name of a spcified vector array. By default it is NULL, with the active vector array for use. | |
| virtual void | SetCaching (bool _arg) |
| Set/Get the caching flag. If this flag is turned ON, there are two levels of caching for derived concrete class vtkInterpolatedVelocityField and one level of caching for derived concrete class vtkCellLocatorInterpolatedVelocityField. Otherwise a global cell location is always invoked for evaluating the function values at any point. | |

Detailed Description
vtkCellLocatorInterpolatedVelocityField - A concrete class for obtaining the interpolated velocity values at a point.
Description vtkCellLocatorInterpolatedVelocityField acts as a continuous velocity field via cell interpolation on a vtkDataSet, NumberOfIndependentVariables = 4 (x,y,z,t) and NumberOfFunctions = 3 (u,v,w). As a concrete sub-class of vtkAbstractInterpolatedVelocityField, it adopts vtkAbstractCellLocator's sub-classes, e.g., vtkCellLocator and vtkModifiedBSPTree, without the use of vtkPointLocator ( employed by vtkDataSet/vtkPointSet::FindCell() in vtkInterpolatedVelocityField ). vtkCellLocatorInterpolatedVelocityField adopts one level of cell caching. Specifically, if the next point is still within the previous cell, cell location is then simply skipped and vtkCell:: EvaluatePosition() is called to obtain the new parametric coordinates and weights that are used to interpolate the velocity function values across the vertices of this cell. Otherwise a global cell (the target containing the next point) location is instead directly invoked, without exploiting the clue that vtkInterpolatedVelocityField makes use of from the previous cell (an immediate neighbor). Although ignoring the neighbor cell may incur a relatively high computational cost, vtkCellLocatorInterpolatedVelocityField is more robust in locating the target cell than its sibling class vtkInterpolatedVelocityField.
