<DIV> </DIV>
<DIV>Including the header file "vtkImageData.h" resolve the problem.<BR></DIV>
<DIV> </DIV>
<DIV>This relationship is actually inheritance: <B><TT>vtkImageData</TT></B> is a subclass of <B><TT>vtkDataSet</TT></B>. The only way for the compiler to know this relationship is to include the header file of the subclass, that is: #include "vtkImageData.h"<BR></DIV>
<DIV>Thanks a lot</DIV>

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