Detailed Description

reconstructs a surface from unorganized points.

Revision:

Thanks:

Thanks to Tim Hutton (MINORI Project, Dental and Medical Informatics, Eastman Dental Institute, London, UK) who developed and contributed this class.

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

Member Function Documentation

virtual const char* vtkSurfaceReconstructionFilter::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 vtkSurfaceReconstructionFilter::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 vtkSurfaceReconstructionFilter::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.

vtkSurfaceReconstructionFilter* vtkSurfaceReconstructionFilter::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 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 vtkSource.

vtkSurfaceReconstructionFilter* vtkSurfaceReconstructionFilter::New (    )  [static]

Construct with NeighborhoodSize=20. Reimplemented from vtkStructuredPointsSource.

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 float vtkSurfaceReconstructionFilter::GetSampleSpacing (    )  [virtual]

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

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

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

void vtkSurfaceReconstructionFilter::Execute (    )  [protected, virtual]

This method is the old style execute method Reimplemented from vtkSource.
