vtkContour, to add to my final report.

Asunto: Re: [vtkusers] 3D Rendering of an sliced object
Hi OnezerO,
What is wrong with showing part of a cube during your final examination?
Alternatively you could try this:
double scalarRange[2];
importer->GetOutput()->GetScalarRange(scalarRange);
[snip]
imageConstantPad->SetConstant(scalarRange[0]);
Cheers,
Sylvain

like a part of a cube, didnt, work

Hi OnezerO,
Before your final examination, make these changes to your code:
// executing the filter
m_vtkImporter->Update();
// getting the extent of the input image m_vtkImporter->GetWholeExtent(
extent );
// creating the extent for an image that has one more 'slice'
// in the 6 directions around the input image
extent[0]--;
extent[1]++;
extent[2]--;
extent[3]++;
extent[4]--;
extent[5]++;
// creating the extended image, so the input image is padded with zeros
// i.e. black voxels vtkImageConstantPad *m_vtkConstant =
vtkImageConstantPad::New(); m_vtkConstant->SetInput(
m_vtkImporter->GetOutput() ); m_vtkConstant->SetOutputWholeExtent(
extent );
Cheers,
Sylvain

Because if this get to work i have to present this in a final
examination and i have to know how to works every part of the code
Thanks

Hi OnezerO,
Could you try the code I sent you in my previous email (see below)?
Cheers,
Sylvain
OnezerO wrote:

I did that:
ConnectPipelines(m_itkExporter , m_vtkImporter );
m_vtkImporter->Update();
vtkImageConstantPad *m_vtkConstant = vtkImageConstantPad::New();
m_vtkConstant->SetInput( m_vtkImporter->GetOutput() );
vtkContourFilter *m_vtkContour = vtkContourFilter::New();
m_vtkContour->SetInput( m_vtkConstant->GetOutput() );
The 3d image obtained its equals to the previous one
You say i should try this extent thing ?

Hi OnezerO,
The filter vtkImageConstantPad is in the Imaging directory:
<a class="moz-txt-link-freetext" href="http://www.vtk.org/doc/nightly/html/classvtkImageConstantPad.html">http://www.vtk.org/doc/nightly/html/classvtkImageConstantPad.html</a>
int extent[6];
image->GetWholeExtent( extent )
extent[0]--;
extent[1]++;
extent[2]--;
extent[3]++;
extent[4]--;
extent[5]++;
vtkImageConstantPad *constantPad = vtkImageConstantPad::New();
constantPad->SetInput(image);
constantPad->SetOutputWholeExtent(extent);
vtkContourFilter *contourFilter = vtkContourFilter::New();
contourFilter->SetInput(constantPad->GetOutput());
Cheers,
Sylvain

Hi OnezerO,
Did you use vtkConstantPadFilter before applying vtkContourFilter as
it was answered previously?
Cheers,

<pre wrap="">Hello, i'm send this post again because i think that i dont explain
my problem very well... I have a series of images that represents a
3d figure, this images was preprocesing with itk i'm receiving it
with a Importer from vtk, i pass the data throught a Contourfilter
and then by a SmoothFilter, the resulting 3d images has openings
upside and downside, i wanna close this holes... how i do it???
