<br>
So here is what I have tried:<br>
<br>
      /  vtkSmartPointer<vtkPlanes> planes =<br>
vtkSmartPointer<vtkPlanes>::New();<br>
        vtkSmartPointer<vtkPoints> origins = vtkSmartPointer<vtkPoints>::New();<br>
        origins->SetNumberOfPoints(1);<br>
        origins->InsertNextPoint(plane->GetOrigin());<br>
        vtkSmartPointer<vtkDoubleArray> normalsArray =<br>
vtkSmartPointer<vtkDoubleArray>::New();<br>
        normalsArray->SetNumberOfComponents(3);<br>
        normalsArray->SetNumberOfTuples(1);<br>
        normalsArray->SetComponent(0,0,plane->GetNormal()[0]);<br>
        normalsArray->SetComponent(0,1,plane->GetNormal()[1]);<br>
        normalsArray->SetComponent(0,2,plane->GetNormal()[2]);<br>
        planes->SetPoints(origins);<br>
        planes->SetNormals(normalsArray);<br>
        mainMapper->SetClippingPlanes(planes);/<br>
<br>
But this gives me a memory access error when reaching the last line.<br>
According to the debuger, the error is located in the for loop of the<br>
SetClippingPlanes() method which is in turn in the call to:<br>
/void vtkAbstractMapper::RemoveAllClippingPlanes(){if ( this->ClippingPlanes<br>
) //.../<br>
<br>
Would you happen to know what's wrong with what I've done there. I can't<br>
really understand where the error comes from<br></blockquote></div></div></div>
