What kind of a 3D rendering do you want? MPR, MIP, MINIP, SSD, VRT? <br>
For example for SSD rendering you can try this:<br>
<br>
vtkMarchingContourFilter *contour=vtkMarchingContourFilter::New();<br>
contour->SetInput(reader->GetOutput());<br>
contour->SetValue(0,-500);<br>
contour->Update();<br>
<br>
vtkStripper *stripper=vtkStripper::New();<br>
stripper->SetInput(contour->GetOutput());<br>
<br>
vtkPolyDataMapper *polyDataMapper=vtkPolyDataMapper::New();<br>
polyDataMapper->SetInput(stripper->GetOutput());<br>
polyDataMapper->ScalarVisibilityOff();<br>
<br>
vtkProperty *prop=vtkProperty::New();<br>
prop->SetColor(1,1,0.940);<br>
prop->ShadingOn();<br>
prop->BackfaceCullingOff();<br>
<br>
vtkActor *actor=vtkActor::New();<br>
actor->SetMapper(polyDataMapper);<br>
actor->SetProperty(prop);<br>
actor->RotateX(90.0);<br>
actor->VisibilityOn();<br>
<br>
qvtk->GetRenderer()->AddActor(actor);<br>
qvtk->GetRenderer()->ResetCameraClippingRange();<br>
<br>
contour->Delete();<br>
stripper->Delete();<br>
polyDataMapper->Delete();<br>
prop->Delete();<br>

attempting to use vtkDICOMImageReader to read a directory of DICOM
images and display them to a qt QVTKWidget in 3D. I’m able to display
a 2D image (that’s not scrollable), but not render in 3D. Does anyone
have any example code out there for rendering this sort of thing in 3D?<o:p></o:p></span></p>
