typedef vtkStreamTracer vtkPStreamTracer::Superclass

| Reimplemented from vtkStreamTracer. Definition at line 50 of file vtkPStreamTracer.h.

## Constructor & Destructor Documentation

vtkPStreamTracer::vtkPStreamTracer | ( |  | ) | `[protected]`

vtkPStreamTracer::~vtkPStreamTracer | ( |  | ) | `[protected]`

## Member Function Documentation

virtual const char* vtkPStreamTracer::GetClassName | ( |  | ) | `[virtual]`

| Reimplemented from vtkStreamTracer.

int vtkPStreamTracer::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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkStreamTracer.

virtual int vtkPStreamTracer::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 vtkTypeRevisionMacro found in vtkSetGet.h. Reimplemented from vtkStreamTracer.

vtkPStreamTracer* vtkPStreamTracer::SafeDownCast | ( | vtkObject * | o | ) | `[static]`

| Reimplemented from vtkStreamTracer.

void vtkPStreamTracer::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 vtkStreamTracer.

vtkPStreamTracer* vtkPStreamTracer::New | ( |  | ) | `[static]`

| Construct object to start from position (0,0,0), integrate forward, terminal speed 1.0E-12, vorticity computation on, integration step length 0.5 (unit cell length), maximum number of steps 2000, using 2nd order Runge Kutta and maximum propagation 1.0 (unit length). Reimplemented from vtkStreamTracer.

void vtkPStreamTracer::SetController | ( | vtkMultiProcessController * | controller | ) |

| Set/Get the controller use in compositing (set to the global controller by default) If not using the default, this must be called before any other methods.

virtual vtkMultiProcessController* vtkPStreamTracer::GetController | ( |  | ) | `[virtual]`

| Set/Get the controller use in compositing (set to the global controller by default) If not using the default, this must be called before any other methods.

virtual char* vtkPStreamTracer::GetInputVectorsSelection | ( |  | ) | `[virtual]`

| If you want to generate traces using an arbitrary vector array, then set its name here. By default this in NULL and the filter will use the active vector array.

void vtkPStreamTracer::SelectInputVectors | ( | const char * | fieldName | ) | `[inline]`

| If you want to generate traces using an arbitrary vector array, then set its name here. By default this in NULL and the filter will use the active vector array. Definition at line 68 of file vtkPStreamTracer.h. References vtkStreamTracer::SetInputVectorsSelection().

void vtkPStreamTracer::Execute | ( |  | ) | `[protected, virtual]`

| This method is the old style execute method Reimplemented from vtkStreamTracer.

void vtkPStreamTracer::ExecuteInformation | ( |  | ) | `[protected, virtual]`

| Reimplemented from vtkSource.

void vtkPStreamTracer::ComputeInputUpdateExtents | ( | vtkDataObject * | output | ) | `[protected, virtual]`

| Do not let images return more than requested. Reimplemented from vtkDataSetToPolyDataFilter.

void vtkPStreamTracer::SetInterpolator | ( | vtkInterpolatedVelocityField * |  | ) | `[protected]`

void vtkPStreamTracer::ForwardTask | ( | float | seed[3],
|  | int | direction,
|  | int | isNewSeed,
|  | int | lastid,
|  | int | currentLine
| ) | `[protected]`

int vtkPStreamTracer::ProcessTask | ( | float | seed[3],
|  | int | direction,
|  | int | isNewSeed,
|  | int | lastid,
|  | int | currentLine
| ) | `[protected]`

int vtkPStreamTracer::ReceiveAndProcessTask | ( |  | ) | `[protected]`
