Detailed Description

splat points with Gaussian distribution.

Date:: 2000/12/10 20:08:38

Revision:: 1.36

vtkGaussianSplatter is a filter that injects input points into a structured points dataset. As each point is injected, it "splats" or distributes values to neighboring voxels in the structured points dataset. Data is distributed using a Gaussian distribution function. The distribution function is modified using scalar values (expands distribution) or normals/vectors (creates ellipsoidal distribution rather than spherical).

Member Function Documentation

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

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkDataSetToStructuredPointsFilter.

int vtkGaussianSplatter::IsTypeOf ( const char * type ) [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 vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkDataSetToStructuredPointsFilter.

virtual int vtkGaussianSplatter::IsA ( const char * type ) [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 vtkDataSetToStructuredPointsFilter.

vtkGaussianSplatter* vtkGaussianSplatter::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. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkDataSetToStructuredPointsFilter.

void vtkGaussianSplatter::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 vtkSource.

vtkGaussianSplatter* vtkGaussianSplatter::New ( ) [static]

Construct object with dimensions=(50,50,50); automatic computation of bounds; a splat radius of 0.1; an exponent factor of -5; and normal and scalar warping turned on.
Reimplemented from vtkStructuredPointsSource.

void vtkGaussianSplatter::ComputeModelBounds ( )

Compute the size of the sample bounding box automatically from the input data.

void vtkGaussianSplatter::SetSampleDimensions ( int i,

int j,

int k

Set / get the sharpness of decay of the splats

virtual float vtkGaussianSplatter::GetExponentFactor ( ) [virtual]

virtual void vtkGaussianSplatter::SetEccentricity ( float ) [virtual]

Control the shape of elliptical splatting. Eccentricity is the ratio of the major axis (aligned along normal) to the minor (axes) aligned along other two axes.
