VTK Documentation


FloatingPointType

vtkFloatingPointType has to be replaced with double

<syntaxhighlight lang="cpp"> - vtkFloatingPointType point[3]; + double point[3]; </syntaxhighlight>


versionMacros

When vtk version macros (like VTK_MAJOR_VERSION) are used, the following header has to be included:

<syntaxhighlight lang="cpp"> +#include <vtkVersionMacros.h> </syntaxhighlight>


Pipeline changes

VTk Docu


Example 1

<syntaxhighlight lang="cpp"> anotherFilter->SetInput(aFilter->GetOutput()); </syntaxhighlight>

should become

<syntaxhighlight lang="cpp"> anotherFilter->SetInputConnection(aFilter->GetOutputPort()); </syntaxhighlight>


Example 2

<syntaxhighlight lang="cpp"> vtkDataObject* output = aFilter->GetOutput(); anotherFilter->SetInput(output); </syntaxhighlight>

should become

<syntaxhighlight lang="cpp"> anotherFilter->SetInputConnection(aFilter->GetOutputPort()); </syntaxhighlight>


Example 3

<syntaxhighlight lang="cpp"> vtkPolyData *pd = vtkPolyData::New(); aFilter->SetInput(pd); </syntaxhighlight>

should become

<syntaxhighlight lang="cpp"> vtkPolyData *pd = vtkPolyData::New(); aFilter->SetInputData(pd); </syntaxhighlight>


Update on vtkData

Since vtkData Objects no longer have a source, the update method is not existing anymore. Instead, call the update method of the source directly.


CxxRevisionMacro

Deprecated Macro. Just remove it.

<syntaxhighlight lang="cpp"> -vtkCxxRevisionMacro(vtkPVAxesActor, "$Revision$"); </syntaxhighlight>


vtkTypeRevisionMacro

Renamed macro

<syntaxhighlight lang="cpp"> - vtkTypeRevisionMacro(vtkPVAxesActor,vtkProp3D); + vtkTypeMacro(vtkPVAxesActor,vtkProp3D); </syntaxhighlight>


allocateScalars

Example 1

Replace

<syntaxhighlight lang="cpp"> int vtkMyAlg::RequestInformation(vtkInformation*, vtkInformationVector**, 

      vtkInformationVector* outInfoVec)

{ 

  vtkImageData* output = this->GetOutput();
  output->GetScalarType();
  output->GetNumberOfScalarComponents();

</syntaxhighlight>

with

<syntaxhighlight lang="cpp"> int vtkMyAlg::RequestInformation(vtkInformation*, vtkInformationVector**, 

      vtkInformationVector* outInfoVec)

{ 

   vtkInformation* outInfo = outInfoVec->GetInformationObject(0);
   vtkImageData::GetScalarType(outInfo);
   vtkImageData::GetNumberOfScalarComponents(outInfo);

</syntaxhighlight>


Example 2

<syntaxhighlight lang="cpp"> int vtkMyAlg::RequestData(vtkInformation*, vtkInformationVector**, 

      vtkInformationVector* outInfoVec)

{ vtkImageData* output = vtkImageData::GetData(outInfoVec); // Allocate output scalars here output->GetScalarType(); output->GetNumberOfScalarComponents(); </syntaxhighlight>

This code does not need to be changed.
