[vtkusers] conversion from vtkImageData to vtkDataObject

[Martine Lefevre]

Thanks Sercani nd Francoi for your quiik relpy.
 
Including the header file "vtkImageData.h" resolve the problem.

 
This relationship is actually inheritance: vtkImageData is a subclass of vtkDataSet. The only way for the compiler to know this relationship is to include the header file of the subclass, that is: #include "vtkImageData.h"

Thanks a lot
Martine

Hi Martine;
Actually vtkImageData inherits from vtkDataSet and it inherits from vtkDataObject, so you may use vtkImageData as a vtkDataObject object. I am using vtkImageData as an input for vtkPolyDataAlgoritm and i get no error…There must be some other stuff that causes error…
Best Regards,
Sercani…

Hi,
I'd like to compute the curvature of an 3D object and I got the following error:
error C2664: 'void vtkPolyDataAlgorithm::SetInput(vtkDataObject *)' : cannot convert parameter 1 from 'vtkImageData *' to 'vtkDataObject *'.
So my question is how I can convert form vtkImageData to vtkDataObject.
Thanks 
Martine
