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).

Examples:

Member Function Documentation

void vtkGaussianSplatter::ComputeModelBounds (    )

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

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.

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.

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.

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::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::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.

virtual void vtkGaussianSplatter::SetAccumulationMode (  int    )  [virtual]

Specify the scalar accumulation mode. This mode expresses how scalar values are combined when splats are overlapped.

virtual void vtkGaussianSplatter::SetCapping (  int    )  [virtual]

Turn on/off the capping of the outside parts of the structured point set by setting to a specified cap value.

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

Specify the cap value to use.

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.

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

Set / get the sharpness of decay of the splats

virtual void vtkGaussianSplatter::SetModelBounds (  float   , float   , float   , float   , float   , float    )  [virtual]

Set / get the (xmin,xmax, ymin,ymax, zmin,zmax) bounding box in which the sampling is performed.

virtual void vtkGaussianSplatter::SetNormalWarping (  int    )  [virtual]

Turn on/off the generation of elliptical splats.

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

Set / get the radius of propagation of the splat. This value is expressed as a percentage of the sampling structured point set. Smaller numbers greatly reduce execution time.

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

Set / get the dimensions of the sampling structured point set.

virtual void vtkGaussianSplatter::SetScalarWarping (  int    )  [virtual]

Turn on/off the scaling of splats by scalar value.

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

Multiply Gaussian splat distribution by this value.
