Member Function Documentation

void vtkGridSynchronizedTemplates3D::ComputeInputUpdateExtents vtkDataObject   output [protected, virtual]
 

What is the input update extent that is required to produce the desired output? By default, the whole input is always required but this is overridden in many subclasses.

Reimplemented from vtkPolyDataSource.

void vtkGridSynchronizedTemplates3D::GenerateValues int    numContours,
float    rangeStart,
float    rangeEnd
[inline]
 

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.

void vtkGridSynchronizedTemplates3D::GenerateValues int    numContours,
float    range[2]
[inline]
 

Generate numContours equally spaced contour values between specified range. Contour values will include min/max range values.

virtual const char* vtkGridSynchronizedTemplates3D::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 vtkStructuredGridToPolyDataFilter.

int* vtkGridSynchronizedTemplates3D::GetExecuteExtent   [inline]
 

Needed by templated functions.

unsigned long int vtkGridSynchronizedTemplates3D::GetMTime   [virtual]
 

Because we delegate to vtkContourValues

Reimplemented from vtkObject.

int vtkGridSynchronizedTemplates3D::GetNumberOfContours   [inline]
 

Get the number of contours in the list of contour values.

float vtkGridSynchronizedTemplates3D::GetValue int    i [inline]
 

Get the ith contour value.

void vtkGridSynchronizedTemplates3D::GetValues float *    contourValues [inline]
 

Fill a supplied list with contour values. There will be GetNumberOfContours() values in the list. Make sure you allocate enough memory to hold the list.

float* vtkGridSynchronizedTemplates3D::GetValues   [inline]
 

Get a pointer to an array of contour values. There will be GetNumberOfContours() values in the list.

virtual int vtkGridSynchronizedTemplates3D::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 vtkStructuredGridToPolyDataFilter.

int vtkGridSynchronizedTemplates3D::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 vtkStructuredGridToPolyDataFilter.

vtkGridSynchronizedTemplates3D* vtkGridSynchronizedTemplates3D::New   [static]
 

Instantiate object with no start, end, or progress methods.

Reimplemented from vtkPolyDataSource.

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 vtkSource.

vtkGridSynchronizedTemplates3D* vtkGridSynchronizedTemplates3D::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 vtkStructuredGridToPolyDataFilter.

virtual void vtkGridSynchronizedTemplates3D::SetComputeGradients int    [virtual]
 

Set/Get the computation of gradients. Gradient computation is fairly expensive in both time and storage. Note that if ComputeNormals is on, gradients will have to be calculated, but will not be stored in the output dataset. 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 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 void vtkGridSynchronizedTemplates3D::SetComputeScalars int    [virtual]
 

Set/Get the computation of scalars.

void vtkGridSynchronizedTemplates3D::SetInputMemoryLimit long    limit
 

This filter will initiate streaming so that no piece requested from the input will be larger than this value (KiloBytes).

void vtkGridSynchronizedTemplates3D::SetNumberOfContours int    number [inline]
 

Set the number of contours to place into the list. You only really need to use this method to reduce list size. The method SetValue() will automatically increase list size as needed.

virtual void vtkGridSynchronizedTemplates3D::SetNumberOfThreads int    [virtual]
 

Get/Set the number of threads to create when rendering

void vtkGridSynchronizedTemplates3D::SetValue int    i,
float    value
[inline]
 

Set a particular contour value at contour number i. The index i ranges between 0<=i<NumberOfContours.
