Detailed Description

abstract filter class.

2/17/94 1.8

vtkDataSetToDataSetFilter is an abstract filter class. Subclasses of vtkDataSetToDataSetFilter take a dataset as input and create a dataset as output. The form of the input geometry is not changed in these filters, only the point attributes (e.g. scalars, vectors, etc.).

This is an abstract filter type. What that means is that the output of the filter is an abstract type (i.e., vtkDataSet), no matter what the input of the filter is. This can cause problems connecting together filters due to the change in dataset type. (For example, in a series of filters processing vtkPolyData, when a vtkDataSetToDataSetFilter or subclass is introduced into the pipeline, if the filter downstream of it takes vtkPolyData as input, the pipeline connection cannot be made.) To get around this problem, use one of the convenience methods to return a concrete type (e.g., vtkGetPolyDataOutput(), GetStructuredPointsOutput(), etc.).

Reimplemented from vtkDataSetSource. Reimplemented in vtkAsynchronousBuffer, vtkCellDerivatives, vtkProjectedTexture, vtkTextureMapToBox, vtkAttributeDataToFieldDataFilter, vtkBrownianPoints, vtkCastToConcrete, vtkCellDataToPointData, vtkDicer, vtkElevationFilter, vtkExtractTensorComponents, vtkFieldDataToAttributeDataFilter, vtkGhostLevelToScalarFilter, vtkIdFilter, vtkImplicitTextureCoords, vtkInterpolateDataSetAttributes, vtkMergeDataObjectFilter, vtkMergeFilter, vtkOBBDicer, vtkPointDataToCellData, vtkProbeFilter, vtkProgrammableAttributeDataFilter, vtkProgrammableFilter, vtkSimpleElevationFilter, vtkTextureMapToCylinder, vtkTextureMapToPlane, vtkTextureMapToSphere, vtkThresholdTextureCoords, vtkTransformTextureCoords, vtkVectorDot, and vtkVectorNorm.

vtkDataSetToDataSetFilter* vtkDataSetToDataSetFilter::SafeDownCast (  vtkObject *    o )  [static]

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned.
