Detailed Description

generate isosurface from rectilinear grid

vtkRectilinearSynchronizedTemplates is a 3D implementation (for rectilinear grids) of the synchronized template algorithm. Note that vtkContourFilter will automatically use this class when appropriate.

Warning:: This filter is specialized to rectilinear grids.

Member Function Documentation

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

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

Reimplemented from vtkPolyDataAlgorithm.

static int vtkRectilinearSynchronizedTemplates::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 vtkRectilinearSynchronizedTemplates::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 vtkRectilinearSynchronizedTemplates* vtkRectilinearSynchronizedTemplates::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkPolyDataAlgorithm.

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

void vtkRectilinearSynchronizedTemplates::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 vtkRectilinearSynchronizedTemplates::GetMTime ( ) [virtual]

Because we delegate to vtkContourValues

Reimplemented from vtkObject.

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

virtual int vtkRectilinearSynchronizedTemplates::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.

Note that if ComputeNormals is on, gradients will have to be calculated, but will not be stored in the output dataset.
