Hi,
Hi,
I want to use the application of example (
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Images/ImageSliceMapper) in
example (
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/CurvedReformation)
but when i trying to modifying this, i am getting certain errors. I am
writing my modifying code(in curved reformation example), could you please
tell me the mistakes which i am doing in that. this code is the modified
code of curved reformation example using the code of image slice mapper.
* // Probe the volume with the extruded surface*
* vtkSmartPointer<vtkProbeFilter> sampleVolume =*
* vtkSmartPointer<vtkProbeFilter>::New();*
* // sampleVolume->SetInputConnection(1, imageReader->GetOutputPort());*
*
*
*#if VTK_MAJOR_VERSION <= 5*
* sampleVolume->SetInput(0, surface);*
* #else*
* sampleVolume->SetInputData(0, surface);*
*#endif*
*
*
*/**
* // Compute a simple window/level based on scalar range*
* vtkSmartPointer<vtkWindowLevelLookupTable> wlLut =*
* vtkSmartPointer<vtkWindowLevelLookupTable>::New();*
* double range = imageReader->GetOutput()->GetScalarRange()[1] -*
* imageReader->GetOutput()->GetScalarRange()[0];*
* double level = (imageReader->GetOutput()->GetScalarRange()[1] +*
* imageReader->GetOutput()->GetScalarRange()[0]) / 2.0;*
* wlLut->SetWindow(range);*
* wlLut->SetLevel(level);*
* */*
*
*
* //Reslicing *
* vtkSmartPointer<vtkImageResliceMapper> imageResliceMapper =
vtkSmartPointer<vtkImageResliceMapper>::New();*
*#if VTK_MAJOR_VERSION <= 5*

*
*#else*
* imageResliceMapper->SetInputData(sampleVolume->GetOutputPort());*
*#endif*
* *

* vtkSmartPointer<vtkDataSetMapper>::New();*
* mapper->SetInputConnection(sampleVolume->GetOutputPort());*
* mapper->SetLookupTable(wlLut);*
* mapper->SetScalarRange(0, 255);*
* *
* // Create An Actor*
* vtkSmartPointer<vtkActor> actor =*
* vtkSmartPointer<vtkActor>::New();*
* actor->SetMapper(mapper);*
**/*
*
*
* // Create a renderer,*
* vtkSmartPointer<vtkRenderer> renderer =*
* vtkSmartPointer<vtkRenderer>::New();*
*
*
* // Create render window*
* vtkSmartPointer<vtkRenderWindow> renderWindow =*
* vtkSmartPointer<vtkRenderWindow>::New();*
* renderWindow->AddRenderer(renderer);*
*
*
*
*
* //Create an interactor*
* vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =*
* vtkSmartPointer<vtkRenderWindowInteractor>::New();*
* renderWindowInteractor->SetRenderWindow(renderWindow);*
* *
* // Add the actors to the scene*
* renderer->AddActor(imageSlice);*
* renderer->SetBackground(.2, .3, .4);*
* *
* // Set the camera for viewing medical images*
* renderer->GetActiveCamera()->SetViewUp(0,0,1);*
* renderer->GetActiveCamera()->SetPosition(0,0,0);*
* renderer->GetActiveCamera()->SetFocalPoint(0,1,0);*
* renderer->ResetCamera();*
* *
* // Render and interact*
* renderWindow->Render();*
* renderWindowInteractor->Start();*
* *
* imageReader->Delete();*

Looking forward your reply soon.
