Detailed Description

reconstructs a surface from unorganized points

vtkSurfaceReconstructionFilter takes a list of points assumed to lie on the surface of a solid 3D object. A signed measure of the distance to the surface is computed and sampled on a regular grid. The grid can then be contoured at zero to extract the surface. The default values for neighborhood size and sample spacing should give reasonable results for most uses but can be set if desired. This procedure is based on the PhD work of Hugues Hoppe: http://www.research.microsoft.com/~hoppe

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

Reimplemented from vtkImageAlgorithm.

static int vtkSurfaceReconstructionFilter::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 vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkImageAlgorithm.

virtual int vtkSurfaceReconstructionFilter::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.

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

Reimplemented from vtkImageAlgorithm.

void vtkSurfaceReconstructionFilter::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 vtkSurfaceReconstructionFilter* vtkSurfaceReconstructionFilter::New ( ) [static]

Construct with NeighborhoodSize=20.

Reimplemented from vtkAlgorithm.

virtual int vtkSurfaceReconstructionFilter::GetNeighborhoodSize ( ) [virtual]

Specify the number of neighbors each point has, used for estimating the local surface orientation. The default value of 20 should be OK for most applications, higher values can be specified if the spread of points is uneven. Values as low as 10 may yield adequate results for some surfaces. Higher values cause the algorithm to take longer. Higher values will cause errors on sharp boundaries.

virtual void vtkSurfaceReconstructionFilter::SetNeighborhoodSize ( int ) [virtual]

Specify the number of neighbors each point has, used for estimating the local surface orientation. The default value of 20 should be OK for most applications, higher values can be specified if the spread of points is uneven. Values as low as 10 may yield adequate results for some surfaces. Higher values cause the algorithm to take longer. Higher values will cause errors on sharp boundaries.

virtual double vtkSurfaceReconstructionFilter::GetSampleSpacing ( ) [virtual]

Specify the spacing of the 3D sampling grid. If not set, a reasonable guess will be made.

virtual void vtkSurfaceReconstructionFilter::SetSampleSpacing ( double ) [virtual]

Specify the spacing of the 3D sampling grid. If not set, a reasonable guess will be made.

virtual int vtkSurfaceReconstructionFilter::RequestInformation	(	vtkInformation *	,
		vtkInformationVector **	,
		vtkInformationVector *
	)			`[protected, virtual]`

Reimplemented from vtkImageAlgorithm.

virtual int vtkSurfaceReconstructionFilter::RequestData	(	vtkInformation *	request,
		vtkInformationVector **	inputVector,
		vtkInformationVector *	outputVector
	)			`[protected, virtual]`

This is called by the superclass. This is the method you should override.

Reimplemented from vtkImageAlgorithm.

virtual int vtkSurfaceReconstructionFilter::FillInputPortInformation	(	int	port,
		vtkInformation *	info
	)			`[protected, virtual]`

Fill the input port information objects for this algorithm. This is invoked by the first call to GetInputPortInformation for each port so subclasses can specify what they can handle.

Reimplemented from vtkImageAlgorithm.
