<p class="MsoNormal">Dear mailing list,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am updating a colleague’s code to compile with vtk6. It contains the following lines from vtk4/5, where the programmer is creating a vtkStructuredPoints. The code is not embedded in a vtk filter. I have indicated the lines which do
not compile.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">std::cout << "Generating seg volume\n";<o:p></o:p></p>
<p class="MsoNormal">vtkStructuredPoints * vol = vtkStructuredPoints::New();<o:p></o:p></p>
<p class="MsoNormal">vol->SetDimensions(dim3d);<o:p></o:p></p>
<p class="MsoNormal">vol->SetExtent(0, dim3d[0] - 1, 0, dim3d[1] - 1, 0, dim3d[2] - 1);<o:p></o:p></p>
<p class="MsoNormal">vol->SetSpacing(spacing[0], spacing[1], spacing[2]);<o:p></o:p></p>
<p class="MsoNormal">vol->SetOrigin(0, 0, 0);<o:p></o:p></p>
<p class="MsoNormal">vol->SetNumberOfScalarComponents(1); // ERROR<o:p></o:p></p>
<p class="MsoNormal">vol->SetScalarTypeToUnsignedChar(); // ERROR<o:p></o:p></p>
<p class="MsoNormal">vol->AllocateScalars(); // ERROR<o:p></o:p></p>
<p class="MsoNormal">vol->GetPointData()->GetScalars()->FillComponent(0,DrEyeLabels::LABEL_NONE);<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I know that SetNumberOfScalarComponents() and SetScalarTypeToUnsignedChar() have been replaced in vtk6 with SetPointDataActiveScalarInfo(), but this method requires a vtkInformation object, and is static, so I can’t see any way to use this
outside of a RequestInformation() method in a filter. Is it possible any longer to create a standalone vtkImage, or is this class now just a shell which can only be configured by a pipeline request?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you<o:p></o:p></p>
