Detailed Description

Superclass for all sources, filters, and sinks in VTK.

vtkAlgorithm is the superclass for all sources, filters, and sinks in VTK. It defines a generalized interface for executing data processing algorithms. Pipeline connections are associated with input and output ports that are independent of the type of data passing through the connections.

Instances may be used independently or within pipelines with a variety of architectures and update mechanisms. Pipelines are controlled by instances of vtkExecutive. Every vtkAlgorithm instance has an associated vtkExecutive when it is used in a pipeline. The executive is responsible for data flow.

Member Typedef Documentation

typedef vtkObject vtkAlgorithm::Superclass

Definition at line 65 of file vtkAlgorithm.h.

Member Enumeration Documentation

enum vtkAlgorithm::DesiredOutputPrecision

Values used for setting the desired output precision for various algorithms. Currently, the following algorithms support changing their output precision: vtkAppendFilter, vtkAppendPoints, vtkContourFilter, vtkContourGrid, vtkCutter, vtkGridSynchronizedTemplates3D, vtkPolyDataNormals, vtkSynchronizedTemplatesCutter3D, vtkTableBasedClipDataSet, vtkThreshold, vtkTransformFilter, and vtkTransformPolyData. SINGLE_PRECISION - Output single-precision floating-point (i.e. float) DOUBLE_PRECISION - Output double-precision floating-point (i.e. double) DEFAULT_PRECISION - Output precision should match the input precision.

Upstream/Downstream requests form the generalized interface through which executives invoke a algorithm's functionality. Upstream requests correspond to information flow from the algorithm's outputs to its inputs. Downstream requests correspond to information flow from the algorithm's inputs to its outputs. A downstream request is defined by the contents of the request information object. The input to the request is stored in the input information vector passed to ProcessRequest. The results of an downstream request are stored in the output information vector passed to ProcessRequest. An upstream request is defined by the contents of the request information object. The input to the request is stored in the output information vector passed to ProcessRequest. The results of an upstream request are stored in the input information vector passed to ProcessRequest. It returns the boolean status of the pipeline (false means failure).
