The following are the list of provided Filters along with a brief description.
This wraps the vtkExtractTensorComponents filter and allows one to select any of the nine components or the effective stress or the determinant from an input tensor data set. This will work for any dataset.
This wraps the vtkExtractUnstructuredGrid filter. From the VTK docs: vtkExtractUnstructuredGrid is a general-purpose filter to extract geometry (and associated data) from an unstructured grid dataset. The extraction process is controlled by specifying a range of point ids, cell ids, or a bounding box (referred to as 'Extent'). Those cells lying within these regions are sent to the output. The user has the choice of merging coincident points (Merging is on) or using the original point set (Merging is off).
This wraps the vtkExtractVectorComponents filter and allows one to select any of the three components of an input vector data attribute.
This wraps the vtkVectorNorm filter and produces an output scalar data with the magnitude of the vector.
This wraps the vtkMaskPoints filter. The problem with this filter is that its output is Polygonal data. This means that if you add this filter to a ModuleManager with visualizations apart from HedgeHog or other velocity vector data you won't see anything! If that happens create another ModuleManager and show the other visualizations there. Also, this means that this filter should be typically inserted at the end of the list of filters.
This wraps the vtkPolyDataNormals filter. vtkPolyDataNormals is a filter that computes point normals for a polygonal mesh. This filter expects an input PolyData. Computing the normals is very useful when one wants a smoother looking surface.
This wraps the vtkThreshold filter. The problem with this filter is that its output is an Unstructured Grid. This means that if you add this filter to a ModuleManager of a gridded dataset and you have a few grid planes, then your grid planes won't show anymore. If that happens create another ModuleManager and show the grid planes there acting on unfiltered data.
This wraps the vtkWarpScalar filter. vtkWarpScalar is a filter that modifies point coordinates by moving points along point normals by the scalar amount times the scale factor. Useful for creating carpet or x-y-z plots.
Warps the geometry using the vtkWarpVector filter. vtkWarpVector is a filter that modifies point coordinates by moving points along vector times the scale factor. Useful for showing flow profiles or mechanical deformation.
