Dicom to stl Conversion #issue

[Sachingit1389]

Thank you so much for making dicom2stl.py
but i got some issues guys please help me solve this error
How to solve this error ? Not getting whats going wrong?Why this AttributeError is coming?

AttributeError: 'module' object has no attribute 'VTK_UNSIGNED_CHAR'

Why this AttributeError is coming?

[dave3d]

It doesn't look like it's finding the type vtk.VTK_UNSIGNED_CHAR from the vtk package. What version of vtkpython are you using?

[Sachingit1389]

Have solved the problem. Actually i was not able to get proper vtk . Then i installed anaconda python . and used pip install vtk as it has its own vtk.

[Sachingit1389]

But now i have issue with the bone ,tissues , etc. extraction
Not able to use: vtkpython dicom2stl.py -t bone -o bone.stl dicom.zip
in place of vtkpython i am using vtk.
But again and again : 'vtk' is not recognized as an internal or external command,
operable program or batch file. i have also set the vtk in environmental variables.

To extract the bone from a zip of dicom images:

vtkpython dicom2stl.py -t bone -o bone.stl dicom.zip

To extract the skin from a NRRD volume:

vtkpython dicom2stl.py -t skin -o skin.stl volume.nrrd

To extract a specific iso-value from a VTK volume:

vtkpython dicom2stl.py -t 128 -o iso.stl volume.vtk

To extract soft tissue from a dicom series in directory and
apply a 180 degree Y axis rotation:

vtkpython dicom2stl.py --enable rotation -t soft_tissue -o soft.stl dicom_dir

and is bone.stl , skin.stl, iso.stl, soft.stl gone be created in the file?

and how to solve this :'vtk' is not recognized as an internal or external command,
operable program or batch file. i have also set the vtk in environmental variables.

[Sachingit1389]

I am using vtk 8.1 which is available through anaconda3

[Sachingit1389]

Sir thank you so much for such a brilliant file. Solved the problem related to vtkpython by installing through conda install -c anaconda vtk then doing pip install vtk.
But sir how can we change the smoothness through command line?

[Sachingit1389]

Now i am able to get bone, skin, iso, softtsissues. But sir how can we change the smoothness through command line?

[dave3d]

I can add a smoothness parameter to the command line.

Update: I've added a '--smooth' command line options to allow you to set the number of iterations of the Laplacian smoothing filter applied to the extracted mesh.
