Member Function Documentation

static vtkGridSynchronizedTemplates3D* vtkGridSynchronizedTemplates3D::New ( ) [static]

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

Reimplemented from vtkPolyDataAlgorithm.

static int vtkGridSynchronizedTemplates3D::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 vtkPolyDataAlgorithm.

virtual int vtkGridSynchronizedTemplates3D::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 vtkPolyDataAlgorithm.

static vtkGridSynchronizedTemplates3D* vtkGridSynchronizedTemplates3D::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkPolyDataAlgorithm.

virtual vtkObjectBase* vtkGridSynchronizedTemplates3D::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkPolyDataAlgorithm.

Reimplemented from vtkPolyDataAlgorithm.

void vtkGridSynchronizedTemplates3D::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 vtkPolyDataAlgorithm.

unsigned long int vtkGridSynchronizedTemplates3D::GetMTime ( ) [virtual]

Because we delegate to vtkContourValues

Reimplemented from vtkObject.

virtual void vtkGridSynchronizedTemplates3D::SetComputeNormals ( int ) [virtual]

Set/Get the computation of normals. Normal computation is fairly expensive in both time and storage. If the output data will be processed by filters that modify topology or geometry, it may be wise to turn Normals and Gradients off.

virtual int vtkGridSynchronizedTemplates3D::GetComputeNormals ( ) [virtual]

Set/Get the computation of normals. Normal computation is fairly expensive in both time and storage. If the output data will be processed by filters that modify topology or geometry, it may be wise to turn Normals and Gradients off.
