Detailed Description

sample unstructured points onto structured points using the method of Shepard

vtkShepardMethod is a filter used to visualize unstructured point data using Shepard's method. The method works by resampling the unstructured points onto a structured points set. The influence functions are described as "inverse distance weighted". Once the structured points are computed, the usual visualization techniques (e.g., iso-contouring or volume rendering) can be used visualize the structured points.

Warning

The input to this filter is any dataset type. This filter can be used to resample any form of data, i.e., the input data need not be unstructured.

The bounds of the data (i.e., the sample space) is automatically computed if not set by the user.

If you use a maximum distance less than 1.0, some output points may never receive a contribution. The final value of these points can be specified with the "NullValue" instance variable.

virtual int vtkShepardMethod::IsA ( const char *  name )

virtual

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageAlgorithm.

const

void vtkShepardMethod::PrintSelf ( ostream &  os, vtkIndent  indent  )

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkImageAlgorithm.

static vtkShepardMethod* vtkShepardMethod::New ( )

static

Construct with sample dimensions=(50,50,50) and so that model bounds are automatically computed from input. Null value for each unvisited output point is 0.0. Maximum distance is 0.25.

double vtkShepardMethod::ComputeModelBounds	(	double	origin[3],
		double	ar[3]
	)

Compute ModelBounds from input geometry.

virtual int* vtkShepardMethod::GetSampleDimensions ( )

virtual

Specify i-j-k dimensions on which to sample input points.

virtual void vtkShepardMethod::GetSampleDimensions ( int  data[3] )

virtual

Specify i-j-k dimensions on which to sample input points.

void vtkShepardMethod::SetSampleDimensions	(	int	i,
		int	j,
		int	k
	)

Set the i-j-k dimensions on which to sample the distance function.

void vtkShepardMethod::SetSampleDimensions

(

int

dim[3]

)

Set the i-j-k dimensions on which to sample the distance function.

virtual void vtkShepardMethod::SetMaximumDistance ( double  )

virtual

Specify influence distance of each input point. This distance is a fraction of the length of the diagonal of the sample space. Thus, values of 1.0 will cause each input point to influence all points in the structured point dataset. Values less than 1.0 can improve performance significantly.

virtual double vtkShepardMethod::GetMaximumDistance ( )

virtual

Specify influence distance of each input point. This distance is a fraction of the length of the diagonal of the sample space. Thus, values of 1.0 will cause each input point to influence all points in the structured point dataset. Values less than 1.0 can improve performance significantly.

virtual void vtkShepardMethod::SetModelBounds ( double  , double  , double  , double  , double  , double    )

virtual

Specify the position in space to perform the sampling.

virtual void vtkShepardMethod::SetModelBounds ( double  [6] )

virtual

Specify the position in space to perform the sampling.

virtual double* vtkShepardMethod::GetModelBounds ( )

virtual

Specify the position in space to perform the sampling.

virtual void vtkShepardMethod::GetModelBounds ( double  data[6] )

virtual

Specify the position in space to perform the sampling.

virtual void vtkShepardMethod::SetNullValue ( double  )

virtual

Set the Null value for output points not receiving a contribution from the input points.

virtual double vtkShepardMethod::GetNullValue ( )

virtual

Set the Null value for output points not receiving a contribution from the input points.

virtual int vtkShepardMethod::RequestInformation ( vtkInformation *  request, vtkInformationVector **  inputVector, vtkInformationVector *  outputVector  )

protectedvirtual

Subclasses can reimplement this method to collect information from their inputs and set information for their outputs.

Reimplemented from vtkImageAlgorithm.

virtual int vtkShepardMethod::RequestData ( vtkInformation *  request, vtkInformationVector **  inputVector, vtkInformationVector *  outputVector  )

protectedvirtual

This is called in response to a REQUEST_DATA request from the executive. Subclasses should override either this method or the ExecuteDataWithInformation method in order to generate data for their outputs. For images, the output arrays will already be allocated, so all that is necessary is to fill in the voxel values.

Reimplemented from vtkImageAlgorithm.

virtual int vtkShepardMethod::FillInputPortInformation ( int  port, vtkInformation *  info  )

protectedvirtual

These method should be reimplemented by subclasses that have more than a single input or single output. See vtkAlgorithm for more information.

Reimplemented from vtkImageAlgorithm.
