Detailed Description

A splatter optimized for splatting single kernels.

vtkFastSplatter takes any vtkPointSet as input (of which vtkPolyData and vtkUnstructuredGrid inherit). Each point in the data set is considered to be an impulse. These impulses are convolved with a given splat image. In other words, the splat image is added to the final image at every place where there is an input point.

Note that point and cell data are thrown away. If you want a sampling of unstructured points consider vtkGaussianSplatter or vtkShepardMethod.

Use input port 0 for the impulse data (vtkPointSet), and input port 1 for the splat image (vtkImageData)

Bug:
Any point outside of the extents of the image is thrown away, even if it is close enough such that it's convolution with the splat image would overlap the extents.
Tests:

virtual const char* vtkFastSplatter::GetClassName (  )  [virtual]

Reimplemented from vtkImageAlgorithm.

static int vtkFastSplatter::IsTypeOf ( const char *  name  )  [static]

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

Reimplemented from vtkImageAlgorithm.

virtual int vtkFastSplatter::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 vtkTypeRevisionMacro found in vtkSetGet.h.

Reimplemented from vtkImageAlgorithm.

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

Reimplemented from vtkImageAlgorithm.

static vtkFastSplatter* vtkFastSplatter::New (  )  [static]

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkAlgorithm.

virtual void vtkFastSplatter::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.

virtual void vtkFastSplatter::SetModelBounds ( double  ,
double  ,

double   
) [virtual]

Set / get the (xmin,xmax, ymin,ymax, zmin,zmax) bounding box in which the sampling is performed. If any of the (min,max) bounds values are min >= max, then the bounds will be computed automatically from the input data. Otherwise, the user-specified bounds will be used.

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

Set / get the (xmin,xmax, ymin,ymax, zmin,zmax) bounding box in which the sampling is performed. If any of the (min,max) bounds values are min >= max, then the bounds will be computed automatically from the input data. Otherwise, the user-specified bounds will be used.

Set / get the (xmin,xmax, ymin,ymax, zmin,zmax) bounding box in which the sampling is performed. If any of the (min,max) bounds values are min >= max, then the bounds will be computed automatically from the input data. Otherwise, the user-specified bounds will be used.

Set / get the (xmin,xmax, ymin,ymax, zmin,zmax) bounding box in which the sampling is performed. If any of the (min,max) bounds values are min >= max, then the bounds will be computed automatically from the input data. Otherwise, the user-specified bounds will be used.
